State the importance of water

1. In the human body
2. To plants
3. In industry
4. In agriculture

Answer 1

In the human body

• It plays an important role in converting food to energy called metabolism.
• Since water diffuses easily through the cell, it is capable of transporting chemicals to and from the cell.
• It helps to maintain our body temperature by means of sweating.

To plants

• It helps in seed germination (since it hydrates and expands the cells of the seed, increasing its respiration and metabolic rate)
• It helps in the process of photosynthesis by providing essential hydrogen to plants, which is necessary for glucose formation.
• Water in soil (containing essential minerals for the growth of plants) enters through the root of plants and reaches to various parts of the plants.

In industry

• It is used in preparing chemicals.
• Water does not heat quickly as compared to other liquids, thus used as a coolant in various fields.
• It is also used in the production of hydroelectricity.

In agriculture

• Water plays an important role in the growth of crops in agriculture
• Around 70% freshwater goes to agriculture
• It is also used to dissolve fertilizers and pesticides so that it can easily transport to various parts of the plant
