Active Transport

- Substances are sometimes absorbed by cells against a concentration gradient (opposite to the way they would diffuse)

- This process requires enegry released from respiration <-- Osmosis doesnt need energy

- Active transport enables cells to absorb material from very dilute solutions


- Root hairs in plants are specialed for absorbing water and minerals by active transport

- The concentration level in the soil is higher…
