Detailed explanation-1: -Cuticle – It is an epidermal layer seen in vascular plants, cells of this layer release cutin which is a waxy substance, preventing water loss from the stomata.

Detailed explanation-2: -A waxy layer known as the cuticle covers the leaves of all plant species. The cuticle reduces the rate of water loss from the leaf surface.

Detailed explanation-3: -Stomata consist of microscopic pores, each flanked by a pair of guard cells. Guard cells can increase or decrease the size of the pore via changes in their turgor status, hence regulating both CO2 entry into the leaf and transpiration, or the loss of water from the leaf.

Detailed explanation-4: -Guard cells are adapted to their function by allowing gas exchange and controlling water loss within the leaf. The size of the stomatal opening is used by the plant to control the rate of transpiration and therefore limit the levels of water loss from the leaf. This helps to stop the plant from wilting .
