Identify the correct statements in relation to C4 photosynthesis.
Kranz anatomy is an essential feature for C4 plants
C4 plants have higher water use efficiency than C3 plants
Photorespiration can be minimised when C3 pathway is in operation
Conversion of oxaloacetate to malate occurs in the bundle sheath cells
A.
Kranz anatomy is an essential feature for C4 plants
B.
C4 plants have higher water use efficiency than C3 plants
C.
Photorespiration can be minimised when C3 pathway is in operation
C4 photosynthesis is the type of biochemical mechanisms (along with C3 and CAM) of photosynthesis used in carbon fixation. The leaves of C4 plants contains two types of chloroplasts, i.e., mesophyll chloroplast and bundle sheath chloroplast. This is known as Kranz anatomy. C4 plants also have higher water use efficiency than C3 plants. Also, if the C4 pathway is in operation in plants, the photorespiratory pathway tend to get minimised.
