State the significant role of Plasma membrane in endocytosis.
Answers
Answer:
The plasma membrane effectively separates the inside of the cell from the outside. Small molecules can be transported across the membrane in a controlled fashion, but the cell surface is impermeable to macromolecules.
Explanation:
Endocytosis is when a cell ingests relatively larger contents than the single ions or molecules that pass through channels. Through endocytosis, a cell can take in large quantities of molecules or even whole bacteria from the extracellular fluid.
The cell membrane plays an important role in this processes. The shape of the membrane itself changes to allow molecules to enter or exit the cell. It also forms vacuoles, small bubbles of membrane that can transport many molecules at once, in order to transport materials to different places in the cell. Also the plasma membrane of the cell forms a pocket around the target particle.
