- Membrane: Made up of phospholipids, which have a hydrophobic tail and hydrophilic head. It is bi-layered. - Active transport: Diffusion of particles assisted by enzymes, requiring energy. - Passive transport: Diffusion of particles not requiring chemical energy. - Facilitated diffusion - Exocytosis/ Endocytosis
