BOTANY

Detailed explanation-1: -The fluid mosaic model describes the structure of the plasma membrane as a mosaic of components-including phospholipids, cholesterol, proteins, and carbohydrates-that gives the membrane a fluid character.

Detailed explanation-2: -Biological membranes are mostly found organized into a lipid bilayer arrangement, in which the spontaneous shape is an intrinsically flat, planar morphology (in relation to the size of proteins).

Detailed explanation-3: -The cell membrane is a multifaceted membrane that envelopes a cell’s cytoplasm. It protects the integrity of the cell along with supporting the cell and helping to maintain the cell’s shape. Proteins and lipids are the major components of the cell membrane.

Detailed explanation-4: -It forms a physical barrier and as a barrier between the cell and the external environment as it allows only selected necessary molecules to pass through it and at the same time prevents entry of unwanted / unnecessary substances. It also regulates the entry and exit of molecules into and out of the cell.

Detailed explanation-5: -The principal components of the plasma membrane are lipids ( phospholipids and cholesterol), proteins, and carbohydrates. The plasma membrane protects intracellular components from the extracellular environment. The plasma membrane mediates cellular processes by regulating the materials that enter and exit the cell.
