Identify the incorrect statement(s) in relation to `C_4`- photosynthesis .

Options

A. Kranz anatomy is an essential feature for `C_4`-plants
B. `C_4`-plants have higer water use efficieny than `C_3`- plants
C. Photorespiration can be minimised when `C_4` - pathway is in operation
D. Conversion of oxaloacetate to malate occrus in the bundle sheath cells

Answer

D

Explanation

`C_4` cycle is a typ4e of biochemical mechansim of photosynthesis , used in carbon fixation. The leaves of `C_4` -plants show undifferentiated mesophyll , connected by plasmodesmata to bundle sheath cells (having two types of chlorophyll , i.e. , mesophyll grand small chloroplast and bundle sheath agranal and large chloroplast . this is known as Kranz anatomy (it is a characteristic feature of `C_4` -plants). `C_4`-plants also have higher water use efficiency than `C_3`-plants.
`C_4` -plants adapted to avoid photorespiration by using enzyme phosphoenolphruvate carboxylase , which is faster than RuBisCO and have more affinity for `CO_2`.
