Which statement best describes a cell membrane?
A
it is found only in animal cells
B
it controls reproduction in the cell
C
it is a cell
D
it controls passage of materials into the cell
Explanation: 

Detailed explanation-1: -Answer: the cell membrane allows the solute to enter the cell which causes the cell to shrink. Explanation: cell membrane is semipermeable membrane, it selectively allows the movement of solute, water, salts, etc.

Detailed explanation-2: -Specialized proteins in the cell membrane regulate the concentration of specific molecules inside the cell. Membrane transport proteins are specific and selective for the molecules they move, and they often use energy to catalyze passage.

Detailed explanation-3: -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-4: -The cell membrane is semipermeable (or selectively permeable). It is made of a phospholipid bilayer, along with other various lipids, proteins, and carbohydrates.
