Key Stage 3
Meaning
A root hair cell is a specialised cell found in roots of plants that is specially adapted to absorb water.
Adaptations of Root Hair Cells
- Root hair cells have a long root hair that gives them a large surface area for absorption of water and minerals.
- The vacuole of the root hair cell stretches into the root hair.
About Root Hair Cells
- Root hair cells are found in the roots of a plant.
Key Stage 4
Meaning
A root hair cell is a specialised cell found in roots of plants that is specially adapted to absorb water.
Adaptations of Root Hair Cells
- Root hair cells have a long root hair that gives them a large surface area for absorption of water and minerals.
- The vacuole of the root hair cell stretches into the root hair.
- There are many mitochondria in the root hair cell to provide the energy required for active transport of scarce minerals.
About Root Hair Cells
- Root hair cells are found in the roots of a plant.
