Answer Details
The excessive loss of water from the leaf is prevented by the cuticle. The cuticle is a waxy layer found on the outermost layer of the leaf that reduces the rate of transpiration by preventing the loss of water through the leaf surface. It helps to retain water within the leaf and prevents desiccation of the plant. The cuticle also provides a barrier to pathogen attack and reduces the loss of nutrients from the leaf surface.
