Question

1. Can you list some reasons why plants need water.

Answer 1

Plants need water due to the following reasons:

• Water is necessary for germinating the seeds of a plant.
• All the nutrients that plants need are soluble in water. The roots absorb the nutrients dissolved in water.
• Plants need water for photosynthesis.
• Photosynthesis is the process by which green plants make their food using Carbon dioxide $\left({\mathrm{CO}}_2\right)$, water $\left({\mathrm{H}}_2\mathrm{O}\right)$ and sunlight, thus producing carbohydrate (sugar) and releasing oxygen $\left({\mathrm{O}}_2\right)$ gas.
