Cell membrane definition class 8. Define the function of plasma membrane. It is of two types, passive diffusion and facilitated diffusion. This organelle is also referred to as plasma membrane.

The cell membrane consists of a lipid bilayer, including cholesterols that sit between phospholipids to maintain their fluidity at various temperatures. The plasma membrane/cell membrane is porous and allows the movement of substances or materials in and out of the cell. This membrane provides shape to the cells of plants and animals.

Cell membrane, also called plasma membrane, thin membrane that surrounds every living cell, delimiting the cell from the environment around it. (ii) it is living part of the cell, thin, delicate and elastic. They are complex living structure.

Cell membrane is a semipermeable membrane that surrounds the cytoplasm of the cell. Cbse class 8 revision notes and key points. The revision notes covers all important formulas and concepts given in the chapter.

It is, however, absent in animal cells. (iv) it is selectively permeable. 2)nucleus is the largest organelle in a cell.

This additional layer which surrounds the cell membrane is necessary for offering the requisite protection to the plants. The cell membrane is the boundary between a cell and the outside world. A cell is always surrounded by a thin membrane called plasma membrane.
