Hey mate, your answer is here :
Even though cacti get the carbon dioxide they need at night, photosynthesis still needs the sunlight. Cacti store the carbon dioxide they take in during the night in their cells in the form a chemical called malic acid.
During the day, the malic acid is converted back to carbon dioxide. With the sun shining, the light reactions can create energy for the Calvin cycle and the carbon dioxide can be converted into sugars. This type of photosynthesis is known as Crassulacean Acid Metabolism because of the storage of carbon dioxide at night as an acid.
As biologists continue to study photosynthesis in plants, they are learning that more plants than just cacti use CAM. For instance, some plants can switch CAM on and off. A few aquatic plants even use CAM photosynthesis. CAM plants are found across the world and demonstrate an important adaptation of plants to their environment when either water or carbon dioxide is in short supply.

Breathing at Night. Even though cacti get the carbon dioxide they need at night, photosynthesis still needs the sunlight. Cacti store the carbon dioxide they take in during the night in their cells in the form a chemical called malic acid. In CAM plants, carbon dioxide is only gathered at night, when the stomata open.
