Question

Answer

The chlorophyll content of leaves will not directly affect transpiration, while temperature, light and wind speed directly affect the transpiration

Answer

Transpiration is process in which water relies from leaves.Temprature,wind speed, light speed directly effect the transpiration as its increase the transpiration
but chlorphyll contents from leaves does not effect directly in transpiration.

Answer

Correct option is bbecause transpiration is process of water moving in plants. And in the process when water receive in leaves then it is mixed with CO2 and chlorophyll which makes food in presence of sunlight by the process of photosynthesis. so we can say that chlorophyll does not directly affect transpiration.

Answer

External factors affecting the rate of transpiration are: atmospheric humidity, temperature, light, wind velocity, atmospheric pressure and available soil water. Some internal factors also affect rate of transpiration e.g., leaf area, leaf structure and age of plants. Chlorophyll content of leaves does not directly affect rate of transpiration.

Answer

Introduction:
Transpiration is the process by which water is lost from the surface of plants in the form of vapor. It plays a vital role in the movement of water and nutrients within the plant. Several factors can directly affect the rate of transpiration, including temperature, wind speed, light, and chlorophyll content of leaves. However, one of these factors does not directly affect transpiration, which is the chlorophyll content of leaves.

Explanation:

a) Temperature:
- Temperature directly affects the rate of transpiration.
- As temperature increases, the rate of transpiration also increases.
- This is because higher temperatures cause the stomata (pores on the leaf surface) to open wider, allowing more water to evaporate.

b) Chlorophyll content of leaves:
- Chlorophyll is responsible for capturing sunlight for photosynthesis.
- It does not directly affect transpiration.
- The presence or absence of chlorophyll does not impact the opening or closing of stomata, which are primarily responsible for transpiration.

c) Wind speed:
- Wind speed directly affects the rate of transpiration.
- When wind blows over the leaf surface, it removes the water vapor surrounding the leaves, creating a concentration gradient that promotes evaporation.
- Higher wind speeds increase the rate of transpiration.

d) Light:
- Light directly affects the rate of transpiration.
- In the presence of light, stomata open wider to allow carbon dioxide to enter the leaf for photosynthesis.
- Open stomata also lead to increased transpiration as water vapor is lost through the leaf surface.

Conclusion:
The chlorophyll content of leaves does not directly affect transpiration. Transpiration is primarily influenced by temperature, wind speed, and light. While chlorophyll is important for photosynthesis, it does not play a direct role in the regulation of transpiration.
