The organelle that allows substances to enter and leave the cell is the plasma membrane, also known as the cell membrane. It is a lipid bilayer that selectively permeates materials, controlling the movement of ions, nutrients, and waste products in and out of the cell. This selective permeability is essential for maintaining the cell's internal environment and overall homeostasis. Additionally, various proteins embedded in the membrane facilitate transport processes.
