Do different species of plants growing in the same area show the same rate of transpiration at a particular time? Justify your answer.

No, different species of plants growing in the same area does not show the same rate of transpiration at a particular time because the rate of transpiration also depends on internal factors like the morphological characteristics of a plant. For eg: Leaf area, thickness of cuticle, number of stomata and whether it is sunken or not etc. So upon these difference, the rate of transpiration is also dependent.
