Carbon dioxide is essential for Photosynthesis Practical Experiment

Dear viewer/subscriber, if my videos helped you a lot (maybe you aced your exams as a student, or you won the admiration and full attention of your students as a teacher, or you got your techniques right as a hobbyist), then its my humble request if you could take a moment to consider supporting me on anyone of the following platforms:
Patreon : / membership
KZbin channel membership: / @thesingtangpascienceguy
Patreon members and channel members will get exclusive access to members-only perks and added benefits such as free PDF notes, Q&A doubt clearing chat sessions, Experiment video requests, Member shoutouts, Behind the scenes and more.
Or if a monthly payment is not convenient for you right now, you may instead consider supporting me with a one-time thankyou gesture by clicking on the SuperThanks Icon below my videos next to the like dislike buttons. Pay the one-time-only amount that you feel is worth the help and benefit you got from my video. Apart from Subscribing to my channel and sharing it with friends, colleagues and students, you valuable one-time or monthly financial support will really help sustain this channel and make it possible to come up with even more engaging and educational content.
Creating experiment videos involve hundreds and thousands of dollars put into procuring the requisite chemicals, equipments and labware to make a single video. To say that i will be extremely grateful for your support would be an understatement.

Thank you so much !!!!!!!

Why did we used distilled water in control water? Please answer asap because I have exam on 4th

[@TheSingtangpaScienceGuy]

Water does not absorb CO2. Its used as negative control in order to confirm that it is not water but the KOH that ia absorbing CO2

[@Matthew-rv3wr]

What was the independent variable?

Thank you 😊 sir

[@elizabethleonnyefendi301]

Hi! It's a great video! But i wanna ask, can we use any plant to do this experiment?? Thanks

[@TheSingtangpaScienceGuy]

Yes i see no reason why any green plant should not show the same result.

[@elizabethleonnyefendi301]

Ok thank you sm! I have one more question, is that ok if we destarched the plant for 4 days?

[@TheSingtangpaScienceGuy]

​@@elizabethleonnyefendi301 no problem. But if you destarch small and fragile plants for that many days, they will become yellow and may disrupt the flow of the experiment causing inconvenience. For large, bulky and hardy plants, no problem.

[@elizabethleonnyefendi301]

@@TheSingtangpaScienceGuy Ok thank you so muchh

[@nzgamers7258]

Question here, is it compulsory to add distilled water in the control experiment? If so, why?

[@emilio-joaquinkoomson8394]

its been a year lol

[@rajeewaudaya8151]

Can we use NaOH instead of KOH

[@TheSingtangpaScienceGuy]

Yes u can. But KOH is a better CO2 absorber than NaOH

[@Matthew-rv3wr]

What was the dependent and controlled variables

[@TheSingtangpaScienceGuy]

Dependent variable would be the rate of photosynthesis. Independent variable is the amount of CO2 supplied. But experiments like these are not investigative in nature. Its just to demonstrate that CO2 is essential for photosynthesis. So one pot is exposed to free air. One is exposed to air devoid of co2. An investigative experiment would be one where you take many pots of identical plants and expose each one of them to different concentrations of CO2 to find out the effect of an increase or decrease in CO2 on the rate of photosynthesis. In such investigative experiments, knowing the dependent, independent and controlled variables would be crucial. But for mere demonstrative experiments where u only have to prove a point, i,e Light, CO2, Chlorophyll etc are essential for photosynthesis to happen, i dont think knowing the variable carry much weight. I've had this Variables question asked in the comments of almost all my photosynthesis expt videos from viewers. Did your teachers specifically ask you all to find out the variables?

Actually plants convert nitrogen into carbon, so CO2 isn't necessary at all.
