Give the location and the main function of plasma membrane
Answers
Answer:
Plasma membrane imparts shape to the cell.
Plasma membrane protects the cell from injury.
Plasma membrane regulates the cellular semi-permeability, reabsorption, excretion and secretion.
Various cell organelles can be formed within the cell, with the help of plasma membrane.
It regulates cellular interactions in the formation of tissues and the defence against foreign bodies.
The plasmalemma protects a cell from its surrounding environment.
Many membrane proteins serve as enzymes.
The cell membrane separates protoplasm from the external environment to maintain the individuality of the cell.
It also acts as a selectively permeable membrane to allow only specific substances in and out of the cell.
It helps in intake of molecules by active or passive absorption.
It acts as a receptor for various chemical stimuli such as amino acids, hormones and sugars.
In unicellular organisms like Amoeba, pseudopodia are formed by projection of plasma membrane.
Ingestion of food and water by endocytosis or pinocytosis takes place with the help of plasma membrane
provides protection for a cell. It also provides a fixed environment inside the cell. And that membrane has several different functions. One is to transport nutrients into the cell and also to transport toxic substances out of the cell.
