The leaves of cacti are reduced to needles and spines primarily to minimize water loss in their arid environments. This adaptation reduces the surface area exposed to the sun and decreases transpiration, helping the plant conserve moisture. Additionally, the spines can provide some protection from herbivores and help to create shade, further supporting the cactus's survival in harsh conditions. Overall, these modifications are crucial for their adaptation to desert habitats.

Cacti have spines. Evolutionary theory is that the spines were originally leaves, but which reduced in size and form to carry out a new function, as spines, to protect the plant from predators. According to the same theory the stem of the plant became the gas exchange and the 'chlorophyll-containing' 'photosynthesis' part of the plant, thus replacing the functions formerly carried out by and through the leaves.
