Answer:
Aquaporins acts as water channels that conduct water to and fro cell membrane during osmosis
Explanation:
Osmosis is a type of cellular transport in which water moves from a region of low solute concentration to a region of high solute concentration through a semipermeable membrane. The osmotic process occurs with the aid of selective protein channels called AQUAPORINS. They allow only the passage of water and prevent that of ions and solutes.
Aquaporins help in the osmotic process by creating a channel for the passage of water molecules across the membrane. In other words, aquaporins facilitate the speedy movement of water molecules across membranes via osmosis, which is normally slow due to the POLARITY OF WATER MOLECULES.
