Unlike many other plants, cacti have evolved unique mechanisms to carry out photosynthesis efficiently in their dry and hot habitats.
Sunken Stomata: Guarding Every Drop
Cacti have developed a clever adaptation to minimize water loss through transpiration. They have sunken stomata, which are tiny pores on the surface of the plant that allow for gas exchange. These sunken stomata help to reduce water loss by creating a barrier against the outside environment, thereby conserving precious water within the cactus.
The Role Of Cam Photosynthesis
In addition to sunken stomata, cacti utilize a specialized form of photosynthesis known as CAM (Crassulacean Acid Metabolism) photosynthesis. This unique process allows cacti to open their stomata at night to take in carbon dioxide, which is then stored in the form of organic acids. During the day, when the sun is intense and the temperatures are high, the cacti close their stomata to prevent water loss while utilizing the stored carbon dioxide to perform photosynthesis. This efficient adaptation enables cacti to thrive in water-scarce environments.
Cactus Care At Home
