Explanation:
Detailed explanation-1: -Osmosis is a passive transport process during which water moves from areas where solutes are less concentrated to areas where they are more concentrated. Illustration of osmosis. A beaker is divided in half by a semi-permeable membrane.
Detailed explanation-2: -There are two main modes of transport of molecules across any biological membrane. These are passive and active transport. Passive transport, most commonly by diffusion, occurs along a concentration gradient from high to low concentration. No energy is necessary for this mode of transport.
Detailed explanation-3: -Water crosses cell membranes by passive transport and by secondary active cotransport along with ions.
