To protect it from predators in the desert.(: and to reduce the rate of transpiration. In many cases the thorn are formed by the modification of shoot , Thus eliminating the leaves hence the free surface to minimize the transpiration.)
Cactus' leaves are modified into short spikes so as to prevent the excess loss of water through the process of transpiration.....
cactus modifies it's leaves into spines to minimise transpiration
In cactus leaves are absent. Chlorophyll are found in trunk mainly.
A cactus has no leaves.
I think because in a desert, the cactus doesn't find much water. So, to save water it does not expel much water out of itself, and as stomata is responsible for expelling water of the plant, the cactus has less stomata
Cactus are desert plants.Their leaves have turned into thrones.
Leaves provide extra surface area for water to evaporate out of the plant. In the arid desert, plants need all the water they can get.
In cactus leaves are absent. Chlorophyll are found in trunk mainly.
Leaves have evolved into spines on the cactus.

the leaves of a cactus help get the suns nutrition foe the plant to grow None pretty much and formally proper cactus have no leaves only it's convergently evolved cousins do.
A cactus has no leaves.
A cactus draws nutrients and water through the roots. Water is stored in special cells that swell when filled with water. The skin is covered in a waxy film to prevent loss of water by evaporation.
A cactus has no leaves but does have a stem.

No. Some may be considered as leaves but not really. Christmas cactus for instance grows in thin segmented stalks reminiscent of leaves. Cactus flowers have petal that are leafy and green like leaves but not really leaves. barrel cactus and saquaros obviously have no leafy protrusions beyond their flowers.
A cactus leaves get sunlight and they make photosynthesis and they get water from that and they save the water
a cactus has spiny leaves for protection and so the water wont evaporate so easily.
