GENERAL HISTOLOGY

Detailed explanation-1: -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-2: -The plasma membrane Both prokaryotic and eukaryotic cells have a plasma membrane, a double layer of lipids that separates the cell interior from the outside environment.

Detailed explanation-3: -The thin, flexible barrier around a cell that regulates what enters and leaves the cell is known as the cell membrane. Cell membranes regulate cell transport and provide homeostasis for the cell by keeping the intracellular environment separate from the extracellular environment.

Detailed explanation-4: -Cell membranes serve as barriers and gatekeepers. They are semi-permeable, which means that some molecules can diffuse across the lipid bilayer but others cannot. Small hydrophobic molecules and gases like oxygen and carbon dioxide cross membranes rapidly.
