- Active Transport
- Root Hairs
- Specialised for absorbing water and minerals
- Have lots of root hair cells
- Large surface area
- Concentration of minerals is usually higher in root hair cell than in soil
- Normal diffusion wouldn't work
- Would go the other way
- Due to ACTIVE TRANSPORT
- Works against a concentration gradient
- Needs energy released from respiration
- Normal diffusion wouldn't work
- Humans
- Is used when there is a low concentration of nutrients in the gut, but a high concentration in the blood
- Active transport allows nutrients to be taken into the blood
- Despite the fact the concentration gradient is the wrong way
- Active transport allows nutrients to be taken into the blood
- Is used when there is a low concentration of nutrients in the gut, but a high concentration in the blood
- Root Hairs
