Which side of the leaf has more stomata?
Name the following:
A plant having sunken stomata.
Mark the most appropriate answer in the following:
In the mechanism of opening and closing of stomata, the important factor is
Assertion (A): The loss of excess water from the aerial parts of the plant in the form of water vapor is known as transpiration.
Reason (R): Stomata of the leaf perform transpiration.
Name the following:
The openings on the barks of trees through which transpiration occurs.
Give a reason/suitable explanation.
