Plant Pigments

[@ericsbuds]

Im having a great time going back through all your series. So glad I found your channel 😁

[@maryamabdi7241]

How does this guy know that which topic I am going to study?! Thanks for teaching so good!

[@rodentnolastname6612]

"Flavonoids" may be one of my favorite words of all time.

[@bassyranasinghe7151]

I could not agree more young "Rodent Nolastame". By the way, I am quite fond of your last name, any chance you can make it mine xx

[@kneelbeforedean8189]

Why flavonoids?

[@rodentnolastname6612]

I think "Flavonoids" is whatever alien species Guy Fieri is 😃

[@karsonali241]

Sorry to be so off topic but does someone know a tool to get back into an Instagram account?? I somehow lost the account password. I love any assistance you can give me

[@aisyahmoktarroji167]

What a good explanation! I’ve been always confused about pigment. Thank your for the wonderful explanation!!!

[@jonnyblaze2692]

Just a small correction to submit. It has been found that green light wavelengths are absorbed, just not at the same levels. Dr Bruce Bugbee has some excellent research on absorption spectrum and PAR

Thanks Dave, looking forward to more on botany

I kinda need this now chemistry jesus thank you ❤️

[@isai1331]

Great video, thanks! Also betalains is an important one imo

[@RapidBlindfolds]

Nature has its own kind of synaesthesia, colours have tastes

[@islamlover6363]

Very important topic in botany

[@tomburns70]

I didn't see your first segment in the series I will eventually though: Still, this segment was not too difficult and I appreciate the clarity in which you present it.

Dave , plz explain kirchhoff's law...

[@pamelafrancis4476]

Thank you for explaining this so well. The autumn colours of leaves are used in Buddhists' robes by the way.

[@KendrixTermina]

So the orange stuff in leaves is the same as in what makes vegetables orange, & its job is to help absorb light, cool. ...now that I think about it, some leaves really are the exact same shades of reds, yellows & oranges as peppers, carrots and fruits.

[@physicslab5787]

Great explanation ❤️

Hi professor kindly clear my confussion why did we find agr z in tangnt inverse neither cot sin or any other trignometric.function in cmplex can u plzz reply.me i m.requesting u for.all reason about this concept

[@sandeepsahanicodes]

Because ,in trigonomentry the tangent or tan is only function which ratio gives (y/x)in complex numbers for representing cartesian coordinate into polar coordinate form.which is easy to find arg z or @.Otherwise you can use sine or cosine function to calculate agr z it will give same answer.we can write x=rcos@ and y=rsin@ where "r" is the length of line segment from origin to given point let say p(x,y). Let you have a given Cartesian coordinate p(5,12) and you have to convert it into polar form. so,we know that in the given example x=5 and y=12. we have to find "r" which is equal to sqrt(x^2+y^2).so, r=sqrt(5^2+12^2)=13 r=13. for finding @ we use @=arctan(y/x)=arctan(12/5)=67.3 degree we also know x=rcos@ and y=rsin@ cos@=x/r or @=arc(x/r)=arccos(5/13)=67.38degree sin@=y/r or @=arcsin(y/r)=arcsin(12/13)=67.38degree in all the cases the values of arg z or @ is same. in polar coordinate system p(5,12) is p(13,67.38). so,we can say that without finding the value of "r" which is sqrt(x^2+y^2) we can find the arg z in complex no. by applying @=arctan(y/x).Thank you :)

[@timetonic]

can you engineer "mutant red grass/moss"? end product - colored grass - is this possible?

[@ritris5165]

I'm so confused on what exactly a 'pigment' is. First you say Chlorophyll is a plant pigment Then immediately after say Chlorophylls are large molecules with a cyclic portion that binds to a metal ion. So is Chlorophyll a pigment or is the pigment a part of chlorophyll? Or do 'pigments' not exist in reality and are just an abstraction to describe the phenomena of light?

[@baseeraslam436]

Is the exciting of the electron by absorbing a photon in the chlorophyll molecule analogous to the photoelectric effect?

[@ProfessorDaveExplains]

Not really, check out my tutorial on photosynthesis to see exactly what's happening.

Wut abt betalain pigments??

[@flyingfox1679]

Hi, I’ve been watching this channel for a while, and I’ve learned a lot about science. I was wondering, are you going to make a debunking video of anti vaxxers? Feel like that’s needed especially during this time. (Sorry if my English isn’t that good)

[@ProfessorDaveExplains]

yep at some point definitely

[@flyingfox1679]

Professor Dave Explains thank you for the answer. I look forward to it.
