PATHOLOGY

Detailed explanation-1: -Cell membranes define cells, and so are fundamental to our understanding of biology. Much more than just a barrier between inside and outside, the cell membrane controls what passes in and out of cells, provides structure and allows cells to communicate with one another.

Detailed explanation-2: -Why is the Cell Membrane Important? The cell membrane is an essential component of the cell’s overall function. The cell membrane provides an important barrier that protects the cell’s interior. The cell membrane also keeps molecules like proteins, carbohydrates, and nucleic acids inside the cell.

Detailed explanation-3: -The selectively-permeable cell membrane protects the cell. It maintains the balance in the internal environment of the cell by transporting the toxic substances outside the cell and bringing the nutrients inside the cell.

Detailed explanation-4: -The cell membrane is selectively permeable to ions and organic molecules and controls the movement of substances in and out of cells. The basic function of the cell membrane is to protect the cell from its surroundings. It consists of the phospholipid bilayer with embedded proteins.
