there is no effect on the rate of transpiration.

Detailed explanation-1: -Transpiration is closely related to stomata. Nearly 97 % of water from plants is lost through stomatal transpiration, so the more stomata, the higher the transpiration rate [3].
Detailed explanation-2: -Transpiration is water taken up from the soil and lost through the stomata in the leaves. This loss of water as vapor through stomata is directly related to the degree of stomatal opening, the supply of water to the leaves, and the evaporative demand of the atmosphere surrounding the leaf.
Detailed explanation-3: -Stomata is found in all vascular plants. The opening and closing of the stomata is affected by the environment of the plant, so there is a corresponding relationship between the number of stomata and the environment in which the plant species evolved.
Detailed explanation-4: -Excess water loss (transpiration) causes stomata closure and therefore decreases the photosynthetic rate. Transpiration from the leaves is made mainly through the stomata and partly through the cuticle.
