Did you know the cell is the basic unit of life.

Diffusion is a physical process where molecules of a material move from an area of high concentration to an area of low concentration

parts of the cell The things that make up the cell are called organelles. They are things like the nucleus which controls the activities of the cell and the cell membrane which controls , what goes in and out of the cell and ribosomes make protein

Exocytosis is a process by which a cell transports secretory products through the cytoplasm to the cell membrane.

Diffusion is a physical process where molecules of a material move from an area of high concentration to an area of low concentration

endocytosis is the process by which material is transported into the cell by the folding of the membrane

The membrane is a fluid mosaic. This means that it is flexible and made up of many different types of molecules. Phospholipids form the basic structure of a cell membrane, called the lipid bilayer. Scattered in the lipid bilayer are cholesterol molecules, which help to keep the membrane fluid consistent.

osmosis is a process by which molecules of a solvent tend to pass through a semipermeable membrane from a less concentrated solution into a more concentrated one, there forth equalizing the concentrations on each side of the membrane
