All living cells have a cell membrane and it is probably the most important organelle of a cell. The cell membrane is composed of a phospholipid‚ proteins and carbohydrates. The phospholipids are arranged in a bilayer with the hydrophilic ends facing out and the hydrophobic ends facing the inside of bilayer. Membranes can contain phospholipids with different fatty acids which affects the strength and flexibility of the membrane. There are two different proteins in cell membranes. One is a protein

Transport Systems Essay In single celled organisms‚ nutrients‚ water and various substances that are need for basic cellular processes can easily be transported in and out through the cell membrane. This is an effective transport system for microscopic organisms‚ but multicellular organisms require a more complex transport system to sustain itself. Take humans for example; unlike a cell‚ only the outer layer of skin is in contact with the body’s outside environment. It’s not possible for substances
