The plasma membrane is inside both prokaryotic and eukaryotic cells and it is made up of lipids and proteins and they create the phospholipid bilayer, it surrounds the cytoplasm of the cell, it is semipermeable to ions. Plasma membrane protects the cell from its external environment and transmits cellular signals. Plasma membranes have to be flexible so cells such as, red blood cells and white blood cells, can change shape as they move through capillaries.
Summary: The plasma membrane is important to cells because it protects them and allows cells to move throughout organisms. It is a phosphate bilayer that allows ions to enter a cell.

What shape is the plasma membrane usually?
ReplyDeleteIt doesn't necessarily have a specific shape.
