Hello student here the question is given and the question is regarding this cam plant and we know these cam plant is a stand for the grass zoo lachian acid metabolism so in these type of plant there are several adaptation so they are going to adopt in the dry hot environment and in these dry hot environment they have very less water so water is very less so they have the characteristic to close the stomata closed during day and by closing these stomata they are going to prevent the water loss so here the water loss is prevented by closing of these stomata during the daytime.
01:06
So here the question is about this carbon dioxide fixation.
01:12
So these carbon dioxide temporarily fix at night.
01:24
So this is fixed by night by the enzyme pyruate in all, pyruid carbosphoenol pyruvate carboxylase.
01:36
So these pepcos enzyme is used and this is going to convert these four carbon compound.
01:46
So these four carbon compound is mainly oxaloacetate or malate.
01:56
So this has happened during the night and it is mainly takes place inside the mesophyllus.
02:03
Cell.
02:05
So these mesophyll cells having these four carbon compound, which is the oxaloacetate and malate, and this is going to stored in these mesophyll cells.
02:18
And during daytime, so after this, if they're the during day time, this stomata is closed and they are, this temporarily fixes carbon dioxide...
