Q.) Plants use completely different process for
excretion as compared to animals. Which
one of the following processes is NOT
followed by plants for excretion?

(a) They can get rid of excess water by transpiration.

(b) They selectively filter toxic substances through their leaves.

(c) Waste products are stored as resins and gums in old xylem.

(d) They excrete waste substances into the soil around them.

Ans. (b) They selectively filter toxic substances through their leaves.

Explanation: Plants get rid of oxygen and carbon dioxide through stomata in leaves and lenticels in stems. They get rid of excess water by transpiration. Cellular vacuoles store many plant waste products. Plants get rid of stored solid and liquid wastes by shedding of leaves, peeling of bark and peeling of fruits. Other waste products are stored as resins and gums, especially in old xylem. Plants also excrete some waste substances into the soil around them.
