Water is a raw material used in photosynthesis.
It dissolves mineral salts in the soil, making them available for absorption by roots.
It serves as a medium for the translocation of mineral nutrients and manufactured food in the plant.
It maintains the turgidity of cells, thereby keeping leaves and stems firm.
It is required for seed germination.
It cools the plant during transpiration.

(c) Ways of conserving water in the soil

Mulching the soil surface to reduce evaporation.
Adding humus or organic manure to improve the water-holding capacity of the soil.
Growing cover crops to shade the soil and reduce evaporation and run-off.
Practising contour ridging or terracing to reduce surface run-off and increase infiltration.
