What happens to a spineless cactus depends upon the kind of cactus and its environment. Going spineless may not be the worse thing that can happen to a cactus. In fact, not all cactus plants have spines. For example, the peyote cactus [Lophophora williamsii] is spineless. Its defense mechanism instead is the powerful hallucinogen mescaline that it contains.
The structural adaptations you would notice on a cactus are the spines on it. The spines are there so they don't loose water.
There is no cactus capable of shooting its spines.
Spines protect the plant from animals that would injure it. They also provide some shade for the stem of the plant.
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.
