GENERAL HISTOLOGY

Detailed explanation-1: -The cell membrane controls the movement of substances in and out of cells and organelles, being selectively permeable to ions and organic molecules.

Detailed explanation-2: -The cell membrane, also called the plasma membrane, is found in all cells and separates the interior of the cell from the outside environment. The cell membrane consists of a lipid bilayer that is semipermeable. The cell membrane regulates the transport of materials entering and exiting the cell.

Detailed explanation-3: -Structure of Plasma Membranes The primary function of the plasma membrane is to protect the cell from its surroundings. Composed of a phospholipid bilayer with embedded proteins, the plasma membrane is selectively permeable to ions and organic molecules and regulates the movement of substances in and out of cells.

Detailed explanation-4: -Summary. The plasma membrane is formed by a phospholipid bilayer. The plasma membrane controls what moves inside and outside the cell.

Detailed explanation-5: -When carbohydrate molecules are attached to a protein, the resulting molecule is called a glycoprotein. Glycolipids are important in cell-cell interaction, signal reception and cell differentiation. Glycoproteins are important for enzyme catalysis, immune recognition and structural stability.
