- ROOT HAIR CELLS AND TRANSPIRATION
- ROOT HAIR CELLS
- Covered in tiny ROOT HAIR CELLS
- Increase teh surface area for absorption
- Water enters by OSMOSIS
- Solution inside the cells are more concentrated (fewer water molecules) than the water in the soil
- Water continues to move between cells by osmosis
- Reaches the XYLEM vessels
- Carry it up the leaves
- Covered in tiny ROOT HAIR CELLS
- TRANSPIRATION
- Evapouration of water from the surface of a plant
- Water evapourates fromt he surface area inside the leaf
- Diffuse out throught he open stomata
- Causes more water to rise up the xylem to the leaves for the cells to use photosynthesis
- Diffuse out throught he open stomata
- ROOT HAIR CELLS
