Question

Find the incorrect statement(s) about photosynthesis from the following:

A. The water splitting complex is associated with PS I.

B. $C_{4}$ plants use the $C_{3}$ pathway of ${CO}_{2}$ fixation as the main biosynthetic pathway.

C. In $C_{4}$ plants, photorespiration does not occur.

D.$\ C_{3}$ plants exhibit 'Kranz' anatomy.

E. ATP synthesis in chloroplast occurs through chemiosmosis.

Choose the answer from the options given below:

Options

A.B and C only
B.B only
C.B and E only
D.A and D only

Solution

Sol. [Key Concept: Photosynthesis — identifying the incorrect statement]

The water splitting complex is associated with PS-II. $C_{3}$ pathway is the main biosynthetic pathway for ${CO}_{2}$ fixation in both $C_{3}$ and $C_{4}$ plants.

$C_{3}$ plants do not exhibit 'kranz' anatomy.

ATP synthesis in chloroplast (Photophosphorylation) occurs by chemiosmosis.
