Detailed explanation-1: -Definition. 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 part of the cell that helps maintain homeostasis is the plasma membrane. The plasma membrane is the flexible barrier that surrounds the outside of the cell. The plasma membrane regulates what enters and leaves the cell and allows the cell to keep their internal conditions separate from the environment.

Detailed explanation-3: -Cell membranes enable organisms to maintain homeostasis by regulating the materials that may enter or leave a cell. Some materials easily cross the cell membrane without the input of energy; other materials require energy input in order to cross through the cell membrane.

Detailed explanation-4: -g) Cell Membrane: regulates what enters and leaves the cell.
