Key Stage 1
Meaning
Roots are the part of the plant found underground.
About Roots
- Roots collect water for the plant.
- Some roots also have a bulb.
- Some roots can be eaten, like carrots, ginger and parsnips.
Key Stage 2
Meaning
Roots are an organ in plants used to absorb water and minerals into the plant.
Adaptations
- Roots are specially adapted to absorb water and minerals.
- Some roots grow deep into the ground to collect water when there has not been much rain.
- Plants in the desert have roots that spread over a large area so that when it finally rains they can collect as much water as possible.
- Roots have root hairs to allow the roots to collect water easily from the soil.
Key Stage 3
Meaning
The roots are an organ in a plant.
About The Roots
- The roots have a large surface area to collect water and minerals.
- Water and minerals are absorbed by diffusion from the soil to the roots.
Adaptations of the Roots
- Roots have veins inside them to transport water and minerals to the leaves.
- The roots have root hairs to increase the surface area of the roots. This speeds up diffusion.
