What are the 3 main components of the plasma membrane?

WebbThe plasma membrane is the outer covering of all the cells but in a plant cell, it is present below the cell wall. It is made up of a phospholipid bilayer. Phospholipids are lipids with a phosphate group attached to them. The phospholipids have one hydrophilic head and two hydrophobic tails. The lipid bilayers have embedded proteins. WebbKey points: Prokaryotes are single-celled organisms belonging to the domains Bacteria and Archaea. Prokaryotic cells are much smaller than eukaryotic cells, have no nucleus, and lack organelles. All prokaryotic cells are encased by a cell wall. Many also have a capsule or slime layer made of polysaccharide.
