And the reason for this change is, once again, to minimize the loss of moisture through stomata. At night, when it is cooler, the cactus will open its stomata to take in carbon dioxide for photosynthesis. Cacti expel oxygen into the atmosphere and absorb carbon dioxide, which remains in the form of acid (usuallymalic acid) until the next morning when the plant, in the presence of sunlight, will perform thechlorophyllfunctionand extract the carbon dioxide from the acid to transform it intosugar.

A place that receives less than 10 inches (25 centimeters) of rain per year is considered a desert. The sphere shape reduces the plants surface area, which means that only a small part gets sunlight exposure, avoiding dehydration. The plant stores the carbon dioxide it takes up in the form of malic acid, so that during daylight hours, it can carry out photosynthesis with the stored carbon dioxide and the stomata can remain closed. Cactus plants store water in their stems, which helps keep the plant hydrated during periods of drought. Transpiration is the process by which water vapor escapes from the leaves of a plant. It has developed a feeding mechanism that allows it to eat the prickly pads of the cactus without getting harmed. These events act as "seed storms" carrying countless seeds of desert plants. The thick skin also protects the camel from extreme heat. To survive in the desert, Cactus has the following adaptations: (i) Modified flat green stem that prepares food by photosynthesis and conserves water.

These areas would be equivalent to the branches in the rest of the plants. Cacti have numerous anatomical and behavioral adaptations for absorbing and storing water, preventing water loss, protecting themselves from predators, limiting damage from the hot sun, saving their energy, requiring few resources, and attracting pollinators. All of these effects of climate change make it harder for desert plants to survive and thrive. Different types of cacti produce various types of flowers.
