Question

How do most minerals enter the root?

(a) Through guttation

(b) Through transpiration

(c) Through Active absorption

(d) Through passive absorption

This question was posed to me in my homework.

I would like to ask this question from Mechanism of Absorption of Nutrients in portion Mineral Nutrition of Biology – Class 11

Answer 1

Right option is (c) Through Active absorption

The explanation is: Most minerals enter the root by active absorption into the cytoplasm of epidermal cells. This needs energy in the form of ATP. Some ions also move into the epidermal cells passively.
