From Soil to Leaf
Part 2 — how roots absorb water and minerals, and how water climbs the stem.
In this lesson you will
- Draw and label a root hair and list the features of roots suited for absorbing water
- Trace the path of water across the root and distinguish active from passive uptake of minerals
- Explain root pressure, cohesion, adhesion and transpiration pull, and describe the coloured-water experiment
