How water absorbed by the roots is important for the plants?
उत्तर
The water absorbed by the roots is important for the plant in three main ways:
- Transportation: The water in the plant body transports substances in solution from one part to another.
- Food production: Water is used in producing food (photosynthesis) by combining it with carbon-dioxide from the air in the presence of sunlight.
- Cooling: Water is used to cool the plant by evaporation through leaves when it is hot outside.
