Cacti act like water storage tanks by trapping the water inside their strong fibrous outside.

To keep their water inside.
They have like this nectar or this water inside them to keep them hydrated
The adaptation for an organ pipe cactus are its spines to keep away predators from eating it. The other adaptation is its long narrow arms which are used to keep in water.
Cactus have spongy tissue that absorb water. They are able to keep that water inside for long periods of time, because they do not perspire like other plants.
Because they already have liquid inside of them to keep them from dehydrating.
Cactuses have a waxy coating to help them retain water, and they have spines to keep others from taking their water.
The roots to a cactus are long thick and go very wide and deep. When it rains the roots absorb the water and store it in its leaves. The cactus doesnt need a lot of water. A couple drops a year will keep it alive. Its leaves are protected with spines.
some environmental pressures are lack of food, obviously,and also carnivores.
if it is losing it thru the overflow pipe you need a new radiator cap
