There is no cactus capable of shooting its spines.
Glochids. The spikes on a cactus are called Glochids.
They are green an have spikes on them.
Cactus plants are prickly and contain spikes.
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.
no
no it provides defense only
no there not because if they were they wouldn't sell them at the store.
No, of course not.
The Cactus' roots are extremely long so that they can suck water up from far away and search for the water. They also have a shallow root system to absorb surface water when there is some rain (or even dew). The trunk of the Cactus is also a part of this as it acts as a storing place for the water. The Cactus' spikes are specially there so that insects and animals don't eat it; the spikes are modified leaves, this reduces the amount of water lost through transpiration.
