surrounds the cell; controls what enters/leaves cell; maintains homeostasis
A
vacuole
B
cell wall
C
cell membrane
D
lysosome
Explanation: 

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 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: -The cell membrane helps the organism in its fight to maintain homeostasis. The cell membrane assists in the maintenance of homeostasis by: Maintaining a fluid phospholipid structure.

Detailed explanation-4: -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-5: -The cell membrane, regulates what enters and leaves the cell and also provides protection and support. The cell takes in food and water and eliminates wastes through the cell membrane. The core of nearly all cell membranes is a double-layered sheet called a phospholipid bilayer.
