GENERAL HISTOLOGY

Detailed explanation-1: -By acting as a gatekeeper, the plasma membrane protects the cell from its surroundings and keeps important molecules from leaving the cell, so that the correct balance of molecules is maintained.

Detailed explanation-2: -What Do Membranes Do? 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.

Detailed explanation-3: -Cell membrane The cell membrane encloses the cell. It acts like a gatekeeper-allowing some materials to pass through it, but not others.

Detailed explanation-4: -Cell Membrane: Your Body’s Gatekeeper The cell membrane is the boundary that separates the internal components of the cell from the outside environment.

Detailed explanation-5: -Everything that a plant needs to grow first needs to pass through its cells’ membranes, which are guarded by a sieve of microscopic pores called aquaporins. “Aquaporins (AQPs) are ancient channel proteins that are found in most organisms, from bacteria to humans.
