ANATOMY

Detailed explanation-1: -Answer and Explanation: The cellular plasma membrane, which encloses the cell, regulates the movement of substances in and out of the cell.

Detailed explanation-2: -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-3: -Carbon dioxide and oxygen cannot pass through the cuticle, but move in and out of leaves through openings called stomata (stoma = “hole"). Guard cells control the opening and closing of stomata. When stomata are open to allow gases to cross the leaf surface, the plant loses water vapor to the atmosphere.

Detailed explanation-4: -Just like the night club, the chemistry of the cell membrane serves as a bouncer that restricts the entry of some individuals but allows free passage of others.
