NEET BIOLOGY

Detailed explanation-1: -The cell membrane, also called the plasma membrane, is found in all cells and separates the interior of the cell from the outside environment. The cell membrane consists of a lipid bilayer that is semipermeable. The cell membrane regulates the transport of materials entering and exiting the cell.

Detailed explanation-2: -The plasma membrane is selectively permeable; it regulates what passes from one side to the other. A selectively permeable membrane will allow water to flow freely while limiting the passage of molecules, especially large molecules or those with a charge.

Detailed explanation-3: -Cell membrane regulates the entry and exit of molecules from inside to outside of the cell and outside to inside of the cell.

Detailed explanation-4: -Mitochondria-the powerhouse of the cell that plays a key role in aerobic cell respiration. Cytoskeleton-Important role in cell movement and cell division. Plasma membrane-controls what enters and leaves the cell.

Detailed explanation-5: -Like all other cellular membranes, the plasma membrane consists of both lipids and proteins. The fundamental structure of the membrane is the phospholipid bilayer, which forms a stable barrier between two aqueous compartments.
