The cell membrane, also known as the plasma membrane, is located on the outer surface of the cytoplasm in a plant cell. It surrounds the cell and acts as a barrier, controlling the movement of substances in and out of the cell. The cell membrane is a vital component that helps maintain the cell’s internal environment and protects it from external threats.
In plant cells, the cell membrane is situated just inside the cell wall. The cell wall provides additional support and protection, but it is the cell membrane that plays a crucial role in regulating the cell’s interactions with its environment. The membrane is made up of a phospholipid bilayer with embedded proteins that facilitate various cellular processes, including transport and signaling.
Understanding the location and function of the cell membrane is essential for grasping how plant cells maintain homeostasis and interact with their surroundings.
