$\large{\bf{\red{Role \:of \:Water\: in \:Plants }}}$

Explanation :

Water is the main constituent of protoplasm. The water plays an important role in plants also. It acts as a universal solvent for transporting materials from one part of the plant to the other parts. During photosynthesis, water helps to release oxygen. Turgidity of the growing cells is maintained with water. Various movements of plant organs are controlled by water. The growth of the cells during elongation phase mainly depends on absorption of water. Metabolic end product of respiration is water. The water acts as a temperature buffer as its specific heat is the highest among most liquids (only exception - liquid ammonia). The water shows the properties of cohesion and adhesion which account for the capillary action of water. Also, the availability of water decides not only the number of individuals of each species that are able to survive in a particular area, but it also decides the diversity of life there. Of course, the availability of water is not the only factor that decides the sustainability of life in a region. Other factors like the temperature and nature of soil also matter. But water is one of the major factors which determine life on land.

The importance of water to the life of plants can be emphasized best by enlisting its functions as follows:

1. Water is the main constituent of protoplasm.
2. It is the solvent through which mineral salts are transported from one part of the plant to the other.
3. Various metabolic reactions take place in a medium containing water.
4. It acts as a reactant in numerous metabolic reactions.
5. During photosynthesis, water releases oxygen.
6. Turgidity of the growing cells is maintained with water.
7. Various movements of plant organs like movements in sensitive plant (touch-me-not) are controlled by water.
8. The growth of the cells during elongation phase is mainly dependent on absorption of water.
9. Metabolic end product of respiration is water.
10. It acts as a temperature buffer as its specific heat is highest (only exception-liquid ammonia).
11. It shows the properties of cohesion and adhesion which account for the capillary action of water.
