Structure of cell Both prokaryotic and eukaryotic cells possess the basic features of a plasma membrane and cytoplasm. The plasma membrane is the outermost surface of the cell which separates the cell from the environment. The cytoplasm is the aqueous content within the plasma membrane . Plasma membrane : It is like any other membrane in the cell but it plays a very important function. It forms the border of a cell, so it is also called the cell membrane . It is primarily composed of proteins and phosphalipid. The phospholipids occur in two layers referred to as a bilayer . Protein is embedded within the lipid layer, or attached to the surface of it. The plasma membrane is elastic and very fluid because of protein and lipid. Normally the function of the plasma membrane is that of a gate-keeper. It allows certain important substances to enter and exit the cell. Cytoplasm and organelles : The cytoplasm is a semi-solid substance which is present in the cell and which gives structure, size, shape and foundation to the cell. It is enclosed by the plasma
