To keep their water inside.
They have like this nectar or this water inside them to keep them hydrated
The vacuole stores water and nutrients that help keep the cactus alive.
Cactus don't grow where it is dry, but grow in areas where the periods between rains are long and cactus will store water in their stem to survive these periods. To get a get cactus flowering just keep it dry for 3 months and then give them a lot of water. This will give nature back to the cactus.
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.
some environmental pressures are lack of food, obviously,and also carnivores.
