Question

Identify the INCORRECT statement from the following.

पर्याय

• Some ions are absorbed passively.

• Endodermis allows bidirectional flow of ions by active transport.

• The transport proteins embedded in the cell membrane of the endodermal cells of root select the type and quantity of solutes taken up by roots.

• Active absorption is a physiological process that needs metabolic energy.

Answer 1

Endodermis allows bidirectional flow of ions by active transport.

Explanation:

Active transport permits ions to flow unidirectionally via the endodermis. It is due to the presence of the suberin layer.
