Answer 1

Answer: (D)

The statement in option (d) is incorrect about osmosis. It can be corrected as
Osmosis is the movement of water across cell membrane and it does not require ATP. It is a type of passive transport which occurs from the region of higher concentration to that of lower concentration. ATP is required in case of active transport.
Rest of the statements are correct.
