The excess of water absorbed plants by their roots gets evaporated through the process ofa)Absorptionb)Eliminationc)Transpirationd)ExcretionCorrect answer is option 'C'. Can you explain this answer?

Question

Answer

It is done through the help of transpiration.
As the human beings sweat plants also sweat through the process of transpiration.
With the help of stomata plants evaporate the excessive water.

Answer

Transpiration is the correct answer as the evaporation of excessive amount of water from the leaves. whereas all others are wrong, let's see how?
first ,Absorption is the process of absorption of water by the plant by roots which is also known as osmosis.
Second, Elimination is another term which is not associated with this question. So, it is wrong.
Third, Excretion is the process of removal of waste materials produced by the body after the process of digestion and assimilation is completed.

Answer

Transpiration

Answer

Transpiration:
Transpiration is the process by which excess water absorbed by plants through their roots is evaporated from the leaves and other aerial parts of the plant. It is an important process in the water cycle as it helps in the circulation and distribution of water in the environment.

Process of Transpiration:
Transpiration occurs through the stomata, which are small openings on the surface of leaves, stems, and other aerial parts of the plant. The process of transpiration can be explained in the following steps:

1. Absorption of Water: Plants absorb water from the soil through their roots. The root hairs present on the surface of the roots help in the absorption of water.

2. Transportation of Water: Once water is absorbed by the roots, it is transported through the xylem vessels to the leaves and other parts of the plant. The xylem vessels act like a pipeline, carrying water and dissolved minerals from the roots to the rest of the plant.

3. Evaporation from Stomata: Water vapor is released into the atmosphere through tiny openings called stomata, which are present on the surface of leaves. Stomata are surrounded by guard cells that can open and close the stomatal pore. When the stomata are open, water vapor can escape from the plant.

4. Diffusion of Water Vapor: The water vapor released from the stomata diffuses into the surrounding air. This diffusion process is driven by the difference in water vapor concentration between the inside of the leaf and the outside air.

5. Water Loss: As water vapor is released through transpiration, it creates a negative pressure or tension in the xylem vessels. This tension helps in the upward movement of water from the roots to the leaves against gravity. However, transpiration also leads to water loss from the plant.

Importance of Transpiration:
Transpiration serves several important functions in plants:

1. Water Transport: Transpiration helps in the transport of water and minerals from the roots to the leaves. This upward movement of water is known as the ascent of sap.

2. Cooling Mechanism: Transpiration helps in cooling the plant by evaporating water from the leaf surface. This is similar to how sweating helps in cooling our bodies.

3. Nutrient Uptake: Transpiration creates a suction force that helps in the uptake of nutrients from the soil into the roots.

4. Photosynthesis: Transpiration provides the necessary water for photosynthesis, which is the process by which plants convert sunlight into energy.

In conclusion, transpiration is the process by which excess water absorbed by plants is evaporated through the stomata on the surface of leaves and other aerial parts of the plant. It plays a crucial role in the water cycle and various physiological processes in plants.
