Question

what is cell membrane????????????​

Answer 1

Cell membranes is also known as plasma membranes.it is selectively permeable membranes.

Plasmalemma Or plasma membrane lies on the outside of protoplast and separates it from external environment. Tonoplast occurs around vacuoles.

Most of the eukaryotic cell organelles have their own membrane appears trilaminar Or tripartite with a middle electron transport layer and electron dense layer on either side.

Chemically , it has proteins(60-70%), lipids (20-40% ) and carbohydrates (1-5%).

Lipids are both structural and enzymatic.

Lipids are generally phospholipid with polar hydrophilic heads.

The cell membrane is a biological membrane that separates the interior of all cells from the outside environment which protects the cell from its environment. The cell membrane consists of a lipid bilayer, including cholesterols that sit between phospholipids to maintain their fluidity at various temperatures. Wikipedia
