1. Water Absorption: Through transpiration, water moves out of the plant body and causes water deficit. As a result water is absorbed by the roots.
2. Water Supply: Due to transpiration, water supply is possible throughout the leaves and stems.
3. Food transport: Food is transported to different parts of the plant body as a result of respiration.
4. Cell division: Perspiration indirectly helps in cell division.
5. Physical Growth: Transplantation plays an important role in the physical growth of plants.
6. Extraction of juice: Due to perfusion, circulation pressure deficit occurs. The juice rises upward to equalize this diffusion pressure deficit.
7. Temperature regulation: A lot of heat is generated in various biological processes in the plant body. This heat is released during respiration. Without respiration, the plant would have been scorched to death by the extreme heat.
8. Osmosis: Concentration of cells increases due to perspiration. As a result, the rate of osmosis increases.
9. Prevention of fungal attack: Salt accumulates on the leaf surface due to respiration. This salt prevents fungal attack.
10. Energy release: Most of the heat energy is released in the process of respiration.
11. Flowering and fruiting: Due to respiration, the cells are protected from rosin and flowering and fruiting.
12. Fruit Sweetness: Perspiration helps in fruit formation and increases fruit sweetness.
13. Precipitation: Water vapor released in the process of transpiration condenses and turns into clouds. Rainfall is more in areas where there is more tree cover.
14. Absorption of mineral salts: Due to transpiration, mineral salts are closer to plant roots and can be easily absorbed.
15. Photosynthesis: The water required for the process of photosynthesis is supplied through perspiration.
16. Maintaining water balance: Prasvedana maintains water balance in the plant body.
17. Gaseous exchange: During respiration, CO2 from the environment enters the plant through stomata and O2 leaves.
