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.

Detailed explanation-2: -Cell membrane – Organelle in animal cells that is the barrier between the cell and the environment.

Detailed explanation-3: -Both animal and plant cells have mitochondria, but only plant cells have chloroplasts.

Detailed explanation-4: -The outer lining of a eukaryotic cell is called the plasma membrane. This membrane serves to separate and protect a cell from its surrounding environment and is made mostly from a double layer of proteins and lipids, fat-like molecules.

Detailed explanation-5: -The cell wall of the plant is made of cellulose. Animal cells do not have a cell wall. They have a cell membrane that is an essential barrier that separates the inner parts of the cell from the outside environment while also controlling the movement of substances inside and out of the cell.
