Cacti do not have leaves. The leaves have been replaced by spines.
Cactus have a waxy layer on them to prevent water loss and reduce transpiration
Succulent plants such as cacti have adaptations such as thick, fleshy leaves with a waxy coating to prevent water loss. These adaptations help the plant store water and survive in arid environments with limited water availability.
cuticle is the thick layer outside the leaf to prevent loss of water.
Reduced leaf surface area to minimize water loss through transpiration. Stem modifications, such as succulence, to store water and perform photosynthesis. Waxy cuticle to prevent water loss and spines for defense against herbivores.

To prevent water loss
The two structures in plant leaves that prevent the loss of water are stomata (located in the bottom part of the leaf) and the epidermis (covers the top and bottom of the leaf).
A cactus would have a thicker cuticle compared to an onion leaf. This is because cacti are adapted to withstand harsh desert conditions and need a thicker cuticle to reduce water loss. Onion leaves, on the other hand, do not face the same level of water stress.
The two structures in plant leaves that help prevent the loss of water are the cuticle, a waxy layer on the outer surface of the leaf, and stomata, small openings on the underside of the leaf that can open and close to regulate water loss.

The roots grow deeper to gather more water, the stems are woody and the leaves are waxy to prevent water loss by transpiration, cacti have also evolved other mechanisms to prevent water loss by transpiration.
