Under which of the following conditions, transpiration pull will be maximum.
Under which of the following conditions, transpiration pull will be maximum.
The correct option is A Open stomata, dry atmosphere and moist soil.
The correct option is A.
Explanation for the correct answer
- Transpiration is the loss of water from the plant in the form of water vapors.
- Stomata is the opening present in the leaves of plants that are involved in the exchange of gases and transpiration.
- Less moisture in the atmospheric air(dry air), and humid soil, increase water loss from the plants.
- Opened stomata allow the water vapors to move out of the plant into the atmospheric air.
- Therefore, dry air, humid soil, and opened stomata increase the transpiration pull.
Explanation for incorrect options
Option B:
Humid conditions around the plant in the form of humid air and irrigated soil decrease the transpiration pull even during the opened stomata.
Opt ion C:
Dry soil will decrease the water uptake by the plants. Thus, transpiration pull will decrease during open stomata, dry and humid conditions. During such conditions, plants avoid losing water from their body.
Option D:
Water vapors cannot move out of the plant body through closed stomata. Therefore, transpiration pull will be absent during closed stomata, dry atmosphere, and dry soil.
Open stomata, dry atmosphere, and moist soil conditions promote the transpiration pull.
