Solution

The correct option is C a, d
Correct statements are:

If solute concentration increases in any solution during osmosis, more pressure is required to prevent movement of water.

During exosmosis, water is first lost from cytoplasm and then the from vacuole.

In higher plants, long distance movement of substances can occur through transpiration.

Water, mineral, hormones and some organic nitrogen is mainly transported through xylem.

Q. Which of the following statements is/are not correct?
(i) Water and minerals, and food are generally moved by a mass or bulk flow system.
