The basic structure of cell membranes is a phospholipid bilayer.
Phospholipids have a phosphate group (the head) and a lipid tail.
Facilitated diffusion occurs when a membrane protein binds to a molecule on one side of the cell membrane and then releases it on the other side. This type of transport does not require energy and relies on the concentration gradient to move molecules across the membrane.
Uniport is a type of protein transporter found in cell membranes that facilitates the transport of a single type of molecule across the membrane. It is a passive transport process that relies on the concentration gradient of the molecule being transported.
Active transport requires energy to move a molecule.
The type of cleavage that forms at the beginning of cell division is called furrow or cytokinesis cleavage. This process involves the formation of a contractile ring made of actin and myosin filaments that pinches the cell membrane, resulting in the separation of the two daughter cells.
This membrane is called the fluid mosaic model as it is a mixture of phospholipids, cholesterol, proteins and carbohydrates. Most of the membrane is composed of phospholipid molecules. These allow the membrane to be rather fluid.Embedded in this membrane are proteins which give some structure to the membrane. The 3rd components are proteins or glycolipids. Cholesterol is also found in the membrane. It prevents lower temperatures from inhibiting the fluidity of the membrane and prevents higher temperatures from increasing fluidity.

Carrier proteins are a type of molecule that can be used as a tunnel to move compounds across the cell membrane. These proteins bind to specific molecules and undergo conformational changes to transport them across the membrane. This process is known as facilitated diffusion.
Proteins are often found embedded in the cell membrane. These proteins are called transmembrane or inter-membrane proteins.Cholesterol molecules are also found embedded in the hydrophobic interior of the cell membrane in many species
Aquaporin is a type of membrane protein that facilitates the transport of water molecules across cell membranes. It forms water channels that enable rapid movement of water in and out of cells, helping to regulate water balance and osmotic pressure within the cell.
