Question

Generally, from which of the following parts of the plants, the minerals are remobilised?

(a) Senescent parts

(b) Growing parts of the plant

(c) Younger leaves

(d) Dead tissues

This question was addressed to me during an online interview.

Question is taken from Mechanism of Absorption of Nutrients topic in division Mineral Nutrition of Biology – Class 11

Answer 1

Correct option is (a) Senescent parts

The explanation is: Generally, from the senescent parts of the plants mineral elements are remobilised because as those parts of the plants are going to die, there is no use of those mineral elements as no developmental processes are going to be carried out there.
