Question

Aquaporins are transport channels, which

(I) Are found in both plants and animals
(II) Allow for faster water movement between the cells than osmosis
(III) Allow water molecules to pass during transpiration
(IV) Do not open during drought stress

• A. III and IV
• B. Only II
• C. Only III
• D. I and II

Answer 1

The correct option is D I and II

Aquaporins are integral membrane proteins that form pores in the membrane of biological cells, mainly facilitating transport of water between cells. The cell membranes of a variety of different bacteria, fungi, animal and plant cells contain aquaporins through which water can flow more rapidly into and out of the cells than by diffusing through the phospholipid bilayer.

so the correct option is " I and II'.
