Find theincorrectstatement(s) about photosynthesis from the following :
A. The water splitting complex is associated with PS I.
B. plants use the pathway of fixation as the main biosynthetic pathway.
C. In plants, photorespiration does not occur.
D. plants exhibit 'Kranz' anatomy.
E. ATP synthesis in chloroplast occurs through chemiosmosis.
Choose the answer from the options given below :NEET 2026 (Cancelled)
Options:
Answer:
Solution:
Statement A is incorrect because the water splitting complex is associated with PS II, not PS I.
Statement B is correct because the Calvin cycle ( pathway) is the main biosynthetic pathway for all plants, including plants.
Statement C is correct because plants have a mechanism that increases the concentration of at the enzyme site, preventing RuBisCO from acting as an oxygenase, thus avoiding photorespiration.
Statement D is incorrect because Kranz anatomy is a characteristic feature of plants, not plants.
Statement E is correct because ATP synthesis in chloroplasts is explained by the chemiosmotic hypothesis.
Therefore, the incorrect statements are A and D.
Answer: A and D only
