Hello students, here the question is about the c3 c4 plants.
00:04
So, we have to identify the different ways the c4 and camp plants carry out photosynthesis when compared to c3 plants.
00:11
So, c4 plants, mainly c3 plants carry out standard kelvin cycle for carbon fixation, but c4 plants use two -step process for carbon fixation which involves mesophyll cells and bundled cells that first initially fix co2 in a four carbon compound which is occurring in the mesophyll cell that oxaloacetate.
00:56
Now, this compound is then transported to bundled cells where co2 is released and kelvin cycle occurs.
01:10
So, this is the process for c4.
01:15
C3 plants are adapted to moderate environment condition with ample water availability, but c4 plants are adapted to hot and dry environment with intense sunlight.
01:23
So, their two -step carbon fixation process minimizes the photorespiration that is c2 cycle which conserves water and enhances the efficiency even in condition of higher temperature.
01:32
Next is camp plants.
01:35
Camp plants open their stomata at night to take in co2 and fix it into organic acid...
