Question

Give two reasons why the minerals cannot be passively observed by the roots

Answer 1

Minerals are present in the soil as charged particles which cannot move across the cell membranes. The concentration of minerals in the soil is usually lower than the concentration of minerals in the root. Hence, all the minerals cannot be passively absorbed by the roots.

Answer 2

Hi friend______,

★ All the minerals cannot be passively absorbed by the roots as the concentration of minerals in the soil is usually low and they are present as charged particles.

★ So, they cannot move across cell membranes.

★ These move into the roots by using energy in the form of ATP.

★ Since energy is used it is active absorption.
