Question

Answer

Transportation is example of evaporation as the simple defination of evaporation tells that it is nothing other than conversion of water to gas by the application of heat by sun . The same thing happens here also the water from the leaves get converted to gas by application of heat by sun.

Answer

it is already understood that in the transpiration the water in the trees is converted into vapour so if we go by the options one by one we find that : a) evaporation is the process of conversion of liquid to gas b) the process of conversion of solid into gas c)conversion of gas into liquid d) something entirely different..process that refers to the movement of molecules from a region of high concentration to one of lower concentration. So....as it goes ...(A) is the correct answer

Answer

Transpiration from the leaves of trees is an example of evaporation.

Transpiration is the process by which water is lost from the leaves of plants. It is similar to evaporation, but specifically refers to the loss of water vapor through the stomata (small openings) on the surface of leaves. This process is essential for plants as it helps in the absorption and transport of water and nutrients from the roots to the rest of the plant.

Explanation:
Transpiration occurs due to the following factors:

1. Stomatal Transpiration:
- Stomata are tiny openings on the surface of leaves that control the exchange of gases and water vapor.
- During transpiration, the stomata open to allow the passage of water vapor from the leaf to the surrounding air.
- This water vapor then diffuses from areas of higher concentration (inside the leaf) to areas of lower concentration (outside the leaf).

2. Cohesion-Tension Theory:
- Transpiration is also facilitated by the cohesion-tension theory, which explains the movement of water within plants.
- Water molecules are attracted to each other through cohesion, forming a continuous column of water within the plant's xylem (specialized tissue responsible for water transport).
- As water evaporates from the leaves, it creates a negative pressure (tension) that pulls more water up through the xylem, from the roots to the leaves.
- This continuous movement of water is known as the transpiration stream.

3. Environmental Factors:
- Several environmental factors can influence the rate of transpiration.
- Higher temperatures, lower humidity, and increased air movement can all lead to increased rates of transpiration.
- This is because higher temperatures and lower humidity create a steeper concentration gradient, promoting faster evaporation.
- Additionally, increased air movement helps to remove the water vapor from the leaf surface, maintaining a more favorable concentration gradient.

Conclusion:
In conclusion, transpiration from the leaves of trees is an example of evaporation. It is a crucial process for plants as it helps in the absorption of water and nutrients, as well as the regulation of temperature. Transpiration is influenced by factors such as stomatal opening, the cohesion-tension theory, and environmental conditions.

Answer

Transpiration from the leaves of trees is an example of evaporation. When trees take up more than more water substance,than through the leaves realise the water by the process of Transpiration with the heating of the sun so that water is covered into gas and its is evaporate to the day time.
