Question

How much water does a mango tree can transpire during it’s growing season?
A. 350-750 liters/day
B. 350-1750 litres/day
C. 750-3500 litres/day
D. 1750-3500 litres/day

Answer 1

Transpiration is defined as a process of water movement via a plant and evaporation of water from aerial parts of a plant such as leaves, stems, and flowers. Water, as we know, is very important for plants for the process of photosynthesis. Although plants take up a very huge amount of water a very small amount is used by the plant for growth and metabolism. A very huge amount of it is lost by the process of transpiration.

Complete answer:
Transpiration is an important process occurring in plants as the process of transpiration is helpful for the stomatal aperture to open to allow diffusion of carbon dioxide for the process of photosynthesis in plants. The process of transpiration also cools down plants and changes the osmotic pressure of the cells. By this process of transpiration, a huge amount I.e. up to 97% of total water intake via absorption through roots is lost.
As we know the process of transpiration is closely related to the opening of the stomatal aperture I.e. with this the process of photosynthesis to take carbon dioxide in. This process of photosynthesis is known for the production of energy to induce flowering in mango plants. The most striking feature in mango plants is that mango trees are seemed to be well protected against the excessive loss of water through transpiration and it seems that loss of water in normal season is only just 100literss per day. The frequency of the opening of stomata is high but the stomatal pores are very small. In growing season to increase flowering and therefore with this to increase fruit-bearing in mango plants, there is a great loss of water in the growing season. This transpiration is a very important phenomenon in mango plants. The mango trees transpire a huge amount of water in it’s growing phase/season. The amount of transpiration of water in the growing season of mango plants is 350-750 liters/day
Option -A- 350-750 litres/day
Yes, it is the correct option as mentioned above.

Option -B-350-1750 litres/day
It is an incorrect option.

Option -C- 750-3500 litres/day
It is an incorrect option.

Option -D- 1750-3500 litres/day
It is an incorrect option as plants do not transpire this much amount of water.

So, the correct answer to this question is the option” A” 350-750 liters/day.

Note: Both transpiration and photosynthesis are the most important process of plants. Both phenomena are closely related to the opening of the stomatal aperture and these occur simultaneously. They both have separate importance in plants both during dry and wet conditions.
