NEET 2026 — Biology solution

NEET2026Biology

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:

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

Solution

The water-splitting complex is associated with PS II, not PS I, so statement A is incorrect. Kranz anatomy is a feature of C $_{4}$ plants, not C $_{3}$ plants, so statement D is also incorrect.

C $_{3}$ pathway is indeed the main biosynthetic pathway in both C $_{3}$ and C $_{4}$ plants, C $_{4}$ plants avoid photorespiration, and ATP synthesis in the chloroplast occurs by chemiosmosis. The incorrect set is therefore A and D.
