Water flows through a selectively permeable membrane in a process called , but water molecules cross the membrane more easily through channels of transmembrane proteins called .

Osmosis

Aquaporins

Explanation:

This is because osmosis is the movement of solutes from a region of lower concentration to a region of higher concentration through a permeable membrane.

Aquaporins are lipid bilayer and water pores that serve as channels of transmembrane proteins that allow water to cross the membrane very fast, and they play vital roles red blood cells, plant cells and kidney which help to reduce water lose.
