Cacti typically store water in their stems and can hold anywhere from 80 to 90 of their total weight in water.
Cacti have hairs to not remove too much water .
Cacti can live in the tropics, but they will probably die from too much water. Cacti retain water so if there is too much water, they basically drown. Tropics tend to have clay soil, and cacti need sand because of the way their roots grow and how the sand in the deserts retain the water, and clay might affect the cacti.
they do if they rot (if you water them too much)
Cacti grow in deserts because they don't need as much water as other plants. They retains water and juice inside the plant for a long time. That's why in the desert you always see birds inside cacti. They use it as shelter and food and water.
cacti can hold large amounts of water for long periods of time, so it doesn't need as much rain and when it is hot it can replenish itself just as much as it needs to survive.
Whenever the soil dries out completely it is safe to water your cacti. If you water them to much then they can develop root rot which will kill them.
Cacti and succulents store water in special cells in the plants' body for later use. The skin of the cacti has a waxy coating to prevent water loss.
Cacti are known to not require much water and some are quite edible.
the main plants in a desert are "succulents" (cacti and other) which hold their water in their leaves
no, it is not true. Cacti are full of water.
Water, very little, but it still needs water like any other living thing on this planet. When it rains in the desert, the cacti soaks up as much water as it can possibly hold, it uses very little of it, as it may not rain for centuries in the desert!
