Biology Unit 2 Vocabulary - Homeostasis

movement of particles across a membrane from an area of lower concentration to an area of higher concentration; requires energy

• Active Transport  

• Passive Transport

• Osmosis

• Diffusion

movement of particles from an area of higher concentration to an area of lower concentration; does not require energy
