Cactus flowers are big, and some of them bloom at night. Their flowerscome out at night because they are pollinated by insects or small animals that come out at night. Insects and small animals carry pollen from one cactus to another. Most cacti live in North and South America. Others live in Africa, Madagascar, and Sri Lanka. Cacti do not have very large leaves because large leaves would allow the water to evaporate. When water evaporates, it changes from a liquidto a gas. When it becomes a gas, it is light enough to move through the air. That would be bad for the cactus because the cactus needs the water to live. Some cacti have waxy coatings on their stems, so that water will run down the stem to the roots. Cacti can absorb water from fog in the air, since it does not rain very much in the desert. Most cacti have long roots which can spread out close to...
