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.
ShelchavCactus spines are actually modified leaves. It helps if you think of cactus as a large stem with leaves (spines). One of the main functions of the spines is fairly obvious, which is to protect cacti from predators such as animals and people. Spines will turn away most animals, but there are a few that are not put off by prickly spines. These animals include javelina, pack rats, desert tortoises and even Desert Bighorn sheep.Saguaro (Carnegiea gigantea)A major function of cactus spines serve to provide protection for the cactus from the sun. At first, it is hard to believe that tiny cactus spines offer any real protection from the intense desert sun. But when you consider that a cactus can have thousands of spines and each spine provides a small amount of shade and multiply that by 1,000 - well it becomes easier to believe that spines really do offer some protection from the sun for the skin of the cactus.
In dry climate, the leaves will modify themselves to spines to minimize their water loss by transpiration.
Can be used for rainsticks. The spines are pushed to the inside of the hollow cactus and shells are put in making the sound of rain when inverted. Spines pushed in so the shells don't fall too fast.
