Cell membrane helps in the <u>recognition of certain chemicals.

Further Explanation:
Plasma membrane is an outer boundary of the cell. <u>It is composed of phospholipids and proteins.</u> It is also called selectively permeable membrane because it allows only selective substances to cross. The <u>transportation of these molecules from extracellular fluid to intracellular fluid is called cellular transport.</u> It can be active and passive transport. Active transport required energy for the movement of substances, whereas in passive transport the molecules move across the membrane without using energy.
<u>There are three common cellular substances that can pass through cell membrane are water, carbon di-oxide and oxygen.</u> These substances are transported through passive transport. The <u>carbon di-oxide and oxygen move through the area of higher concentration to lower concentration</u>. The oxygen diffuses into the cell through lipid bilayer because it is more concentrated outside the cell, whereas carbon dioxide diffuses out of the cell because it is more concentrated inside the cell.
<u>Water moves through the membrane by the process called </u><u>osmosis</u>. It moves freely either through protein channels or by slipping between the lipid tails of the membrane. The water comes from higher concentration to lower concentration.
