The spikes protect the stem of the cactus plant. The reason is the stem's responsibility for moving, processing and storing water and watery products and solutions. The stem also is responsible for carrying out the photosynthetic interaction with sunlight to make energizing, life sustaining starches and sugars.
The spikes protect the overall stem, and specific stem parts. For example, the stem is the location of the breathing pores, or stomata. The stomata are the points at which gases within the cactus are exchanged for atmospheric gases. The stem also is the location of the growth buds from which flowers, fruits and seeds form.

Cacti have spikes to use as their defense mechanism to animals that may try to eat them. The spikes deter the animals by pricking them in the nose and mouth putting them off trying to eat it. The spikes also help collect water vapor by increasing the plant's surface area and the spikes also help stop transpiration loss of water through pores.
