Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
moves water into and out of a cell
A
concentration
B
diffusion
C
osmosis
D
selectively permeable membrane
Explanation: 

Detailed explanation-1: -Water moves by osmosis, which is a type of diffusion, into and out of the cell. Through the cell membrane, water molecules flow through osmosis from a lower solute concentration to a higher solute concentration. Water can therefore travel because of a concentration gradient without using any energy.
