प्रश्न
Why are the stomata in most plants more numerous on the lower surface of a leaf instead of being on the upper surface?
Advertisements
उत्तर
The lower surface of leaf is sheltered from direct sunlight. If more stomata are on the upper surface of a leaf, then excessive transpiration would occur, resulting in quick wilting of the plant. Hence most plants have more numerous stomata on the lower surface of a leaf to control the rate of transpiration.
