Why iower epidermis of leaf contains more stomata than upper epidermis?
Because the top of the leaf is covered by the cuticle of the leaf which prevents water loss and transpiration. If there were stomata in the top of the leaf, more water wold be lost and the plant would wilt. The stomata are located in the bottom of the leaf because There is no cuticle there to stop the proccess of transpiration and so doesn’t interfere with the proccess of photosythesis.
