Cell membrane definition and function pdf. The main function of the plasma membrane is to protect the cell from its surrounding environment. Undulation and pseudopodia are cell membrane phenomenon involved in cell movement.amoeba, macrophages and wbcs move with the helps of temporary organelles like pseudopodia. Plasma membrane assisted cell movements:

Plasma membrane of a cell definition function structure video share this post. This is the currently selected item. The plasma membrane of a cell is a network of lipids and proteins that forms the boundary between a cell’s contents and the outside of the cell.

It regulates the movement of materials into and out of the cell and facilitates electrical signaling between them. The cell membrane is a fluid mosaic of proteins floating in a phospholipid bilayer. The cell membrane consists of a lipid bilayer, including cholesterols that sit between phospholipids to maintain their fluidity at various temperatures.

Animal cells are contained in just a membrane. The cell membrane separates the cell from the surrounding interstitial fluid, the main component of the extracellular fluid. Glycoproteins function in the structure, reproduction, immune system, hormones, and protection of cells and organisms.
