The plasma membrane

Question

The plasma membrane

Quizplus · Accepted Answer

The plasma membrane is selectively permeable, meaning it regulates and controls the movement of materials into and out of the cell. This is a critical function in maintaining homeostasis and allowing the cell to interact with its environment. The plasma membrane is composed of a double layer of phospholipids, which form a fluid and flexible barrier. While proteins are also a part of the plasma membrane, they are not the main structural component. The plasma membrane does not separate the nucleus from the rest of the cell - this is the function of the nuclear envelope.
