Question: Describe the structure and chemical composition of plasma membrane?
The plasma membrane is a thin layer that surrounds the cell and separates it from its environment. It is composed of two layers of phospholipids, which are molecules that have a hydrophilic (water-loving) head and a hydrophobic (water-hating) tail. The phospholipids are arranged in such a way that the hydrophilic heads face the water on both sides of the membrane, while the hydrophobic tails face each other in the middle. The plasma membrane also contains proteins, which can act as channels, receptors, enzymes, or markers for the cell. Some proteins span across the entire membrane, while others are attached to only one side. The plasma membrane is selectively permeable, which means that it allows some substances to pass through, but not others. This helps the cell maintain its homeostasis and communicate with other cells.
