Human body composed of trillion of cells. Each cell have cell membrane which are also known as plasma membrane. cell membrane separates the interior from surroundings. fluid mosaic model composed of phospholipids, protein, carbohydrates and cholesterol. Protein helps in transport of materials in and out of the cell. diffusion, facilitated diffusion and active transport occur between cell and external environment.
