PLANT NUTRITION: WATER AND MINERAL SALTS

All plants need watering.
If you do not water a plant, first it withers, then it dies.


Plants take in water through very fine root hairs on their roots.

Plants also need to take in mineral salts from the soil.
Mineral salts dissolve in water, so plants take them in through their roots with the water.
Farmers add fertilisers to the soil because fertilisers contain mineral salts.
