Why is the plasma membrane called a selectively permeable membrane?
Answers
Explanation:
PLASMA MEMBRANE:
•The plasma membrane,better known as a cell membrane regulates the entry and exit of the foreign particles.
•This depends upon the concentration of the substances inside and outside of the cell
•Once a substance enters it can't leave until there is a difference between the concentration of the substances in the cell.
•Generally,the substances are oxygen and water which enter by the processes diffusion and osmosis respectively
•Transfer of substances also occurs by active transport
•Thus,the plasma membrane is known as a selectively permeable membrane
Answer:
Solution : The cell membrane is a very thin layer of protein and fat. It allows only selective substances to pasß through it, hence,it is called a selectively permeable membrane.
