UNIT 3 TEST: Cellular transport

Movement of particles through the cell membrane from high to low concentrations

• diffusion
• photosynthesis
• mitochondria
• active transport

Against the concentration gradient

(low to high) and uses energy/ATP

• facilitated diffusion

• osmosis

• active transport

• diffusion

Allows certain molecules or ions to pass through it by diffusion and doesn't allow others.

• protein
• semi-permeable membrane
• isotonic
• homeostasis

Equal percentage of solutes inside and out. 
Concentration of substances is the same. 

• hypotonic
• isotonic
• nucleus
• hypertonic
