Pls Pls Pls follow me

Answer 2

Answer:

4. They show C2 cycle in mesophyll cells.

is not a feature of C4 plants.

• C4 is a process  by which plants fix carbon during photosynthesis and the plants who followed C4 cycle are known as C4 plants.
• Such plants are called as C4 because the first product of carbon fixation is carboxylic acids which contain 4 carbon atom.
• C4 plants has special characteristics that their leave shows kranz anatomy which means that they can tolerate high temperature,they lack a process called photo respiration,have greater  biomass productivity and are very responsive towards high intensities of light.
