Diffusion, Osmosis, and Active Transport (Edexcel GCSE Biology Combined Science): Flashcards

Movement of particles from higher to lower concentration

Passive (requires no energy)

Water movement from less to more concentrated solution

Same concentration inside & out; no net water movement

Higher external concentration; water moves out

Lower external concentration; water moves in

Swell; develop turgor pressure

Movement from lower to higher concentration (against gradient)

ATP from respiration

Absorbs mineral ions from soil
