The plasma membrane is selectively permeable and regulates the movement of molecules from intracellular spaces to the extracellular spaces.
Further Explanation:
The plasma membrane is also referred to as the cell membrane. It is present in all the eukaryotes and prokaryotes. Some bacteria and plant cell membrane is attached to the cell wall. The plasma membrane is a semi-permeable lipid bilayer.
Plasma membrane plays several functions in the cell, for example:
• They protect the cell.
• Give a fixed environment in the cell
• Transport toxic substance outside the cell
• Help in cell signaling
• Give structural support to the cell
• Transport molecule inside to outside and vice versa.
The plasma membrane is mainly made up of lipids which help to transport molecule. This is because lipid makes cell membrane semi-permeable. They act as a barrier between the environment and the cell. The plasma membrane also made up of proteins and carbohydrates that help in cell signaling.
