Web24 aug. 2024 · Here's Why: 1) The cell membrane, also known as the plasma membrane, is a thin layer that separates the inside of the cell from the outside. Lots of things happen in our cells, including functions that we need to survive, so it is important that the right things are inside the cell when they need to be. 2) In order for the cell membrane to do ... Web7 apr. 2024 · The plasma membrane is the outer membrane of the cell, it delimits the cell itself and a cell interior with specific conditions for the cellular function. Since it is selectively permeable, the plasma membrane has an important role for the passage of substances inwards or outwards. 5 5.
Cell membrane can form different types of "supramembrane" structures such as caveola, postsynaptic density, podosome, invadopodium, focal adhesion, and different types of cell junctions. These structures are usually responsible for cell adhesion, communication, endocytosis and exocytosis.
