Water Uptake
Bayani Gaba-gaba
All the water a plant uses, for photosynthesis, for support and for cooling, starts its journey in the soil and enters through the roots. The entry point is a special cell built for the job: the root hair cell, whose long thin extension reaches between soil particles to drink in water.
In this lesson you will learn how root hair cells are adapted, follow the exact pathway water takes from soil to leaf, and meet a simple staining experiment that lets you see that pathway for yourself. You will also use magnification to work out the real size of a root hair cell from an image.
Manufura
- Identify in diagrams and images root hair cells and state their functions
- State that the large surface area of root hairs increases the uptake of water and mineral ions
- Outline the pathway taken by water through the root, stem and leaf as: root hair cells, root cortex cells, xylem, mesophyll cells
- Investigate, using a suitable stain, the pathway of water through the above-ground parts of a plant
