Cell membranes are mainly made of phospholipids. There are two layers to the phospholipid: hydrophobic & hydrophilic. They bond together to create two layers of phospholipids: Phospholipid Bilayer

Integral Proteins: proteins that allow bigger molecules to bypass the cell membrane

Peripheral Proteins: proteins on the cell membrane's surface that function for signaling, communication, and as an enzyme.

Cholesterols are present in between the phospholipids. It has many functions including changing the fluidity, thickness, compressibility, water penetration and the shape of the bilayer

Carbohydrates are present on the surface of cell membrane. Their job is for cell signaling and communication as well as detection for harmful recognition of harmful cells

Diffusion: The movement of material from high concentration to low concentration

Hypotonic: a solution that has lower solute concentration than another solution. Usually the cell with more water

Hypertonic: a solution that has higher solute concentration than another solution. usually the cell that lack water.

Facilitated Diffusion: When molecules can't directly diffuse through the membrane, they use the protein channels on the cell membrane to facilitate them.

Endocytosis: movement of particles into a cell by enclosing the particle with the cell membrane

Pinocytosis: fluid and liquids outside of the cell membrane are taken into the cell via small vesicles

Exocytosis: the process of cell removing large amounts of material by surrounding and fusing the material with the cell membrane. It is a type of bulk transport

Phagocytosis: a type of endocytosis in which the cytoplasm engulfs the material and consumes it
