[@shinsoujuuzou8423]

I have an explanation for the co2 and o2 jars: for the CO2 jar :even though plants do produce more oxygen and absorb carvon dioxide to make glucose plants also NEED oxygen as like us they do cellular respiration. Since there was not enough oxygen for them to essentially breathe, the cells in the plant died. And I think that bcos the cells died, the chlorophyll in the cells which gives plants the green colour died and it got decoloured. For the oxgen container: even though there was no carbon dioxide for the plants to absorb and make glucose which is essentially their food, plants actually store their excess glucose in the stems and other parts of the plant in the form of starch(edit) so since it still had oxygen to breathe the cells did not die and the plant was living on its food storage from the glucose it had produced prior to the experiment TLDR: CO2 is for food and O2 is for breathing and like humans, plants can survive longer without food than without breath.

Not glycogen. Glucose is stored as either starch or cellulose, with the latter having mostly a structural role, while the former are the actual energy reserves. Glycogen composes animal reserves.

[@culthosmythos]

I have a thought/challenge for you guys. I remember being taught once that when a bean or seed sprouts and sends out it's first roots and shoots, gravity determines which direction they grow, ie the plant "knows" to send the root down towards gravity and the shoot up away from it. SO, that being said, what would happen to the emerging plant to be if its orientation to gravity kept changing, like if it was constantly being rotated slowly- how would THAT affect its growth at all?

My observations as a farmer: the open control obviously lost water to evaporation so that's why it wilted. The open bottle could "breathe" but had less evaporation and a higher humidity around the stem and in the bottle. Plants does well in a humid hot humidity, but so does fungus. In a cool and humid environment you can lose entire crops to funguses. The bottle with the higher oxygen content didn't surprise me either - plants breathe oxygen through the day and if you left the light on 24/7... Furthermore the fact that the CO2 plant smelled like "old grass" didn't surprise me either. Funguses can't grow in a environment with no oxygen so farmers are always using it as a trick to turn grass and corn into silage. The vacuum is also a no brainer - question is why didn't you test a plant in a pressurized environment?

[@benishborogove2692]

Close, but backwards. Plants take in CO2 through the day and use the light energy to turn it into carbohydrates. At night they give off CO2 and water.

[@cerberez]

Great question

[@drasc9058]

Actually plants do "breathe" O2 during the night when they can't do photosynthesis. That's why you can put a plant with the right amount of water into a jar/container and have it sealed with the plant still surviving. Also the reason why the nearly pure CO2 turned bad and the O2 one not might be that mold grows in anaerobic environments as seen in another TKOR video where they put different food items in a sealed vacuum to test if they would turn stale/moldy which to no surprise did happen to much of the food. Another reason could be that because of the high CO2 content some of the CO2 dissolved into the water and made it more acidic which is probably not the best growing condition for basil.

[@mu11668B]

@@Secr3tYT Idk where you got that piece of information from, but nothing produces oxygen for the roots (other than the plants themselves, if the process of photosynthesis contributes any). The oxygen diffuses into the soil from the atmosphere and get absorbed by plants and micro organisms. In fact, the soil is one of the major natural CO2 producer in the carbon cycle. Moreover, if you submerge soil samples under water, then they will quickly become an oxygen-poor environment, thus micro organisms have to harvest energy from less energetic oxidation reactions, eventually ending up with a reductive environment that produces gases like methane.

[@brandonogden3498]

The co2 around the plant can, in a way, “burn” it. The oxygen kind of acts as an air conditioner. That’s why the sealed co2 one didn’t do well.

[@cmawhz]

co2 is acidic after all

[@ram2504]

and plant ned more oxygen then co2

[@problemsolver3254]

There is only 400 in a million parts of co2 in the air so it was 200 time more co2

[@MathewZ788]

Yes after all co2 does trap alot of heat and is slightly acidic

[@Unmannedair]

No. And no to all the replies also. It's really quite simple. Plants breath just like you and me. They take in oxygen and consum it with sugar to grow and stay alive. The byproduct of this is co2 just like you. Plants only make more oxygen than they consume during the day when sunlight can power photosynthesis. That's why everyone saying that the Amazon creates most of the breathable air is demonstratively wrong. The Amazon is oxygen neutral. At night, the plants and animals consume all the extra oxygen produced during the day. Earth's primary oxygen supply comes from diatoms in the ocean.

[@niagargoyle]

Plants don’t breathe CO2; a closer analogy would be to say that they “eat” it. All complex life that we know of performs respiration by absorbing oxygen and expelling CO2, even plants.

[@Vmaster005]

Dont forget about algae, not so complex.

[@niagargoyle]

Vic 1 Yeah, but I needed some qualifier to exclude anaerobes.

[@niagargoyle]

Cyrus Antony It isn’t a perfect analogy, but it’s closer than breathing. The energy comes from the sun; the material comes from the carbon dioxide (CO2) and water (H2O). The plant combines the carbon and the hydrogen (and some of the oxygen) to form carbohydrates and then expel the remaining oxygen. Maybe a better comparison would be herbs, spices, and condiments. It’s not necessarily nourishing, but it makes the food edible.

[@Deez-Master]

I have a degree in plant science and I can shed some light on why the CO2 plant died and the Oxygen plant did just fine. Basically plants still need oxygen. Yes plants use CO2 + Sunlight to make sugars to store the energy of the sun for later and oxygen is a by product here. The important part is that in order to release and harness the energy stored in the sugar they need to use oxygen in the process, creating water and CO2 again. So it's theoretically a closed loop, but in actuality the plant needs both Water and Oxygen and CO2 to be supplied to it in order to thrive in the long run. Reason being that all the pieces need to come together at the right time, all of them need to be plentiful enough to randomly interact in the chaotic mess that is the life of a cell. It's a fine tuned process that has been evolved over millions or billions of years so it is especially adapted to deal with the concentrations similar to those found in nature. In nature O2 makes up ~20% of the atmosphere where as CO2 is 410 parts per million or 0.041% so the plant is going to be a lot more sensitive to the oxygen level going to 0 than the CO2. Another way to think about it is taking away the CO2 stops the plant from storing new energy while taking away all the O2 takes away its ability to release any of its stored energy so it doesn't matter how much more energy it can store with all that CO2 available. Final point here, the marginal amount of CO2 released in the process of the plant breaking down its sugars would be much more significant to the plant because it is used to such low levels. Comparatively the marginal amount of O2 released in photosynthesis is going to seem like nothing when the plant is used to a 20% O2 atmosphere.

[@truffles.xenpai5388]

Forgetting H2O for the photosynthesis

[@PJPEE]

It may have also undergone photorespiration from the excess oxygen causing rubisco to fixate oxygen and output CO2. So the oxygen plant was probably just slowly dying and while the root system was doing just fine.

5:50 What most likely happened is that the “control” was set inside a mason jar where humidity was able to concentrate creating a perfect environment for mold to grow. This is exactly why you did not get the same results with the plant that was left out in the the open or the ones that where closed and/or vacuumed. Most fungi and mold need air and humidity to grow. Of course the spores were already in the environment and/or in the plant before you started. You just gave it the perfect environment to thrive. Hope this was helpful.

[@joshuam5689]

Too much water, probably fungus gnats, and fungal spores from the air either in the lab or from where you got them could be contributing factors to the health of plants. The pure CO2 one suffocated the roots of the plant and the aerobic bacteria and fungi, acidified the soil, and decreased the ability of the plant to use water. The pure O2 allows the roots to breathe and gave the cells enough fuel for respiration (burning stored energy, like animal cells) which may temporarily make up for the lack of photosynthesis, plants are massive carbohydrate/sugar stores afterall. But the pure O2 is probably more reliably explained by creating an atmosphere that's great for the roots and the aerobic bacteria and fungi present in the soil, which then produce carbon dioxide and other nutrients for the plant to use to grow.

The mould on your open control is called botrytis. It's a greyish mould caused, normally by dampness. Basil is actually very prone to it. My family owned a garden centre in the Uk and overwinter or a particularly wet and cold summer we'd lose a lot of our basil plant to it. It's caused by damp air and cold or watering late in the day when it's cold overnight. The best way to prevent it is to water the plant's first thing in the morning so they have all day to dry off and keep them somewhere warmer overnight (if memory serves me correct above 10°C.)

As a landscaper I just thought of this: Infusing some piece of land with liquid nitrogen and seeing how well a plant in that area does

[@Cragified]

Temperature and pressure difference would just result in the nitrogen turning into a gas and returning to the atmosphere. Also plants use Nitrate NO3 not N2. N2 is very unreactive. This is why legume are called 'nitrogen fixing' they take N2 and through a complicated process convert it into NH3. Then bacteria can turn that into NH4, then other bacteria turn that into NO3 and other bacteria turn it into NO3 which plants can use. The other method of nitrogen getting into the soil is from animal urine and feces and decomposers of dead plants. So in effect, other then largely sterilizing the soil for a short term due to the thermal shock and lack of O2 nothing would happen.

Gardening has been big during the lockdown-so much so I saw my first ever Lowe’s billboard sign advertising its Garden Center. What about a test of different types of rooting methods/powders? Rooting being the trimming and replanting of plants to create more plants-give them away as gifts, make your garden bigger. Rooting can be done with simple vegetables-like onions and radish-by sticking the root or leafy portion into water for a few days. But with fruit trees or other plants, rooting can be more difficult, and so they have powders that you can use to sterilize the soil (prevent rotting) and promote root growth on the cut branches. You can use purchased rooting powder, as well as a variety of other methods like honey, cinnamon, aspirins tablets, etc.

For those pondering the one in the vacuum. Plants utilize water to do the job our blood does. At the leaves there are very small openings just large enough for water molecules to evaporate from. This causes a negative pressure (possible in liquids) that pulls water up the plant bringing sugars and minerals up to the leaves. When you put it into a vacuum the water in the soil undergo a phase change into a gas. So the jar was actually filled with water vapor (Hence the water droplets on the inside of the jar) because of this and the conditions it was then impossible for water to evaporate from the leaves and 'pump' up sugars and nutrients since the water vapor atmosphere within was already at its maximum pressure.

No science here. There was no hypothesis being tested and the “control” plants couldn’t be kept alive and healthy.

@@NuttyCuts_ looked to me both a mix of under water and not enough sun, plants like that need a lot.

[@NuttyCuts_]

@@MoonFlux so it wasnt anything to do with the jar? it just needed more sun and water?

@@NuttyCuts_ maybe there could have been. I am just saying how it appears to be. The mold one was because of being to warm and wet, not able to easily dry its leaves.

[@guncrafta8848]

Little correction: Plants need both, CO2 and Oxygen but more CO2 than Oxygen. At day they consume CO2 and at night they consume O2. That has to do with missing sunlight at night so they can not do photosynthesis but when they do "breath" they can live without it. That's what I learned in school

[@truffles.xenpai5388]

Plants take in O2 all the time for aerobic respiration but they only take in CO2 in the day as it is needed in photosynthesis along with water and sunlight

[@Deez-Master]

I have a degree in plant science, hard to say about the mold in the control jar. Completely possible that it(the mold) just enjoyed the elevated humidity from the moist soil + less airflow into the jar compared to a natural setting. No soil is gonna be sterile and plant are constantly fighting fungi so it could just be random chance the fungi in the soil or spores landing on it just happened to be something it couldn't face, or it could be that something about the experimental condition tilted the battle in favor of the fungus

Having researched a bit of hydroponics and aeroponics, 1) Plants definitely need oxygen and that’s one of the reasons aeroponics and hydroponics with aeration into the nutrient solution works as effectively as it does: oxygen availability to the roots. 2) Earth’s base atmosphere is ~20% oxygen whereas CO2 exists in very small amounts relatively. 3) When you’re smelling the sealed jars, you’re not smelling only your test basil plant but any and all soil bacteria that was also trapped into the environment with the plant during your test period. Aerobic bacteria growth vs anaerobic bacteria growth (or suppression/absence) are affected by the sealed environments as well. (Also, sealing and temp affects things like humidity, which definitely affects plant growth and would be much more difficult to control for.)

Or a CO2 only environment. But first, we are going to need bigger jars and vacuum....

[@kalebdye4378]

Ironically, a completely oxygen environment would actually suffocate you.

[@drdrums1]

It depends on the pressure. If the O2 partial pressure is too high, O2 becomes toxic - it will cause seizures and retinopathy, among other bad things. I don't remember the charts (you study this stuff when learning about O2-enriched mixtures for diving, called a "nitrox" blend), but I think 100% pure O2 at sea level pressure is pretty close to, if not above, the oxygen toxicity level. It's also a function of time as well as pressure, so the longer you spend in a hyperoxic environment, the closer you get to oxygen poisoning. Fun fact - diving below 184 feet on regular air will result in oxygen toxicity, because at that depth the gas pressure is enough to increase the O2 partial pressure past the toxicity limit. At that depth, you have to use a hypoxic mixture (less than 21% O2), such as a trimix (air + Helium).

[@LordBlee]

@@drdrums1 02 actually isn't toxic until much deeper, but for recreational diving, there isn't any reason to put yourself at risk. On 32% nitrox you don't usually want to go below ~110 feet.

[@SavageGreywolf]

Here's a factor you may not have thought about, Nate: There are other living things in the soil besides just the plant, like microorganisms. Some of those things may have a symbiotic relationship with the plants. They may also rely on oxygen to survive. It's possible strongly oxygenating the atmosphere of the O2 jar made those creatures thrive, which in turn made the plant thrive. Conversely, filling the sealed CO2 jar may have made those do badly, which led to the plant doing poorly. The open jar still had access to atmosphere so likely despite the CO2 doses such organisms might still be able to survive. It's even possible that the factors of O2, water, etc formed the right mix to allow the jar to serve as a complete closed ecosystem. It's even possible the other jars are as well, but such might not necessarily include the plant: We wouldn't be able to tell unless you let them sit for some time though.

[@oliverstotts4302]

The reason that the oxygen one grew so much was because of the mitochondria being able to make more energy therefore making it grow more. Even though CO2 is also important I guess oxygen is too.

[@raikupwns243]

If you guys plan on doing experiments like this again, I suggest using something like duckweed since it’s small and has fewer requirements, eliminating some of the factors that effected your Basil

[@alx_slav4068]

Cool that you do the old fashion tkr i realy appriciate

[@nyx7860]

So about the plant sealed in the oxygen jar: plants can do cellular respiration as well, so is that why it's still relatively functional?

[@leahbone589]

think of carbon dioxide as food and oxygen as just air, thats why the oxygen one did slightly better than the co2 one

[@adamwheeler1391]

exactly right it probasbly just had food stored up in the form of starch and was able to convert it into energy using the oxygen. The plant in the CO2 could make more food but it couldn't use the food that it made.

[@rafaelgcpp]

The "open control" got too much water. The glass mason jars hold the water for much longer than the planter, and allows fungi to develop...

Plants also respire at night in absense of sunlight . So the plant with oxygen it respired at night produced energy from the stored starch.

For the CO2 jar Nate commented that it looked pickled. When lacto fermenting vegetables you put them in a sealed oxygenless environment and try avoiding air contact and the bacteria generate a lot of co2 in the process, so it may have kinda fermented in a way.

[@adamart8719]

My hypothesis for the success of the oxygen jar is, the oxygen was able to sustain the basil's roots and tissues in a high humidity stagnant environment. the overall issue with this test is plants do regular cellular respiration as in, Burning carbon to produce atp and sustain life (primarily plants use photosynthesis but are not limited to this mechanism). From what I understand plants do this primarily in their roots. Therefore when in a small sealed space plants will 'drown' beacuse without oxygen at the roots plants struggle to maintain their roots health and often are prone to root rot mold and other natural decomposing processes. In order to properly test the effects of atmosphere changes plants will require a suitable Sealed environment were the is enough room for a water cycle. This is usually accomplished by creating a drainage layer where the water in the ecosystem can collect without contacting the main root mass and especially the rhyzome.

[@fathomisticfantasy2681]

I grew a lot of basil one year. It turns out they are really easy to grow. That is if you don't get mold. Basil enjoys a lot of heat during the summer and prefer to be dry enough that bacteria does not grow. I actually love to put fresh cut basil in my morning eggs. If anyone wants to grow basil be mindful not to buy more than two plants unless you really enjoy basil. These things can go crazy in the middle of the summer and you do not want to let them get too big. The stems get extremely hard and keeping them pruned ensures that you can chop them up easily. I recommend growing basil and tomatoes together. They both are very forgiving when it comes to growing them in pots. Use a 5 gallon bucket for the tomatoes and paint the buckets black. Otherwise the sun will scorch them. I personally want to master growing oregano. Its a little more difficult, but totally worth it for canning your own spaghetti sauce.

[@TreeDragon]

You could do a soil pH time lapse! Not as thrilling as the vaccum, but very easy to set up. Pick a plant that prefers a relatively neutral soil pH (most houseplants), then mix different stuff in the soil to different extremes at either end of the pH spectrum?
