GENERAL HISTOLOGY

Detailed explanation-1: -A membrane is the cell’s interface with the rest of the world-it’s gatekeeper, if you will. This phospholipid bilayer determines what molecules can move into or out of the cell, and so is in large part responsible for maintaining the delicate homeostasis of each cell.

Detailed explanation-2: -The cell membrane and some of its embedded proteins. By acting as a gatekeeper, the plasma membrane protects the cell from its surroundings and keeps important molecules from leaving the cell, so that the correct balance of molecules is maintained.

Detailed explanation-3: -The cell membrane, also called the plasma membrane, is found in all cells and separates the interior of the cell from the outside environment. The cell membrane consists of a lipid bilayer that is semipermeable. The cell membrane regulates the transport of materials entering and exiting the cell.

Detailed explanation-4: -The cell membrane surrounds the cell and controls the substances that go into and out of the cell. The nucleus is a structure inside the cell that contains the nucleolus and most of the cell’s DNA. It is also where most RNA is made. The cytoplasm is the fluid inside the cell.

Detailed explanation-5: -The cell membrane can be described as a gatekeeper as its structure determines which materials are allowed to pass in and out of the cell. The cell membrane is described as semipermeable as it allows certain substances to pass through while preventing passage of other materials.
