Detailed explanation-1: -The cell membrane regulates the transport of materials entering and exiting the cell.
Detailed explanation-2: -Mitochondria Structure Mitochondria are shaped perfectly to maximize their productivity. They are made of two membranes. The outer membrane covers the organelle and contains it like a skin.
Detailed explanation-3: -The outer lining of a eukaryotic cell is called the plasma membrane. This membrane serves to separate and protect a cell from its surrounding environment and is made mostly from a double layer of proteins and lipids, fat-like molecules.
Detailed explanation-4: -Nuclear pores, small channels that span the nuclear envelope, let substances enter and exit the nucleus. Each pore is lined by a set of proteins, called the nuclear pore complex, that control what molecules can go in or out.
Detailed explanation-5: -The membrane is a delicate, two-layered structure of lipids and proteins, and it controls what can enter and exit the cell.
