Question

explain briefly about plasma membrane?​

Answer 1

Answer:

⭐The plasma membrane, also called the cell membrane, is the membrane found in all cells that separates the interior of the cell from the outside environment. ... The plasma membrane consists of a lipid bilayer that is semipermeable. The plasma membrane regulates the transport of materials entering and exiting the cell.

⭐Plasma membrane is the outermost layer in cells. It separates the content of cell from their external environment. ... It also allows the materials from cell to exit outside. It controls the entry and exit of materials in nd out of cell and hence it is called selectively permeable membrane.

⭐The plasma membrane, or the cell membrane, provides protection for a cell. It also provides a fixed environment inside the cell. And that membrane has several different functions. One is to transport nutrients into the cell and also to transport toxic substances out of the cell.

Answer 2

Explanation:

=》Plasma Membrane Definition:

☯️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 is also simply called the cell membrane. The main function of the plasma membrane is to protect the cell from its surrounding environment. It is semi-permeable and regulates the materials that enter and exit the cell. The cells of all living things have plasma membranes.

☯️Functions of the Plasma Membrane:

⭐A : Physical Barrier

The plasma membrane surrounds all cells and physically separates the cytoplasm, which is the material that makes up the cell, from the extracellular fluid outside the cell. This protects all the components of the cell from the outside environment and allows separate activities to occur inside and outside the cell.

The plasma membrane provides structural support to the cell. It tethers the cytoskeleton, which is a network of protein filaments inside the cell that hold all the parts of the cell in place. This gives the cell its shape. Certain organisms such as plants and fungi have a cell wall in addition to the membrane. The cell wall is composed of molecules such as cellulose. It provides additional support to the cell, and it is why plant cells do not burst like animal cells do if too much water diffuses into them.
