Crassulacean acid metabolism, also known as CAM photosynthesis, is a carbon fixation pathway that evolved in some plants as an adaptation to arid conditions [1] that allows a plant to photosynthesize during the day, but only exchange gases at night.
It can live in up to 30 ppm Boron in solution, compared to most plants which can tolerate only about 1-5 ppm. [4] As with other desert climate members of the genus Atriplex, it uses water conserving C4 photosynthesis, and it removes salts by having bladders in the leaves that keep the salt from the plant cells.

Photosynthesis (/ ˌ f oʊ t ə ˈ s ɪ n θ ə s ɪ s / FOH-tə-SINTH-ə-sis) [1] is a system of biological processes by which photosynthetic organisms, such as most plants, algae, and cyanobacteria, convert light energy, typically from sunlight, into the chemical energy necessary to fuel their metabolism.
Maize (Zea mays, Poaceae) is the most widely cultivated C 4 plant.[1]In botany, C 4 carbon fixation is one of three known methods of photosynthesis used by plants. C 4 plants increase their photosynthetic efficiency by reducing or suppressing photorespiration, which mainly occurs under low atmospheric CO 2 concentration, high light, high temperature, drought, and salinity.
Xerophytes: Cardón cacti in the Baja California desert, Cataviña region, Mexico. Plants face severe challenges in arid environments. Problems they need to solve include how to obtain enough water, how to avoid being eaten and how to reproduce. Photosynthesis is the key to plant growth. It can only take place during the day as energy from the ...
The following is a breakdown of the energetics of the photosynthesis process from Photosynthesis by Hall and Rao: [6]. Starting with the solar spectrum falling on a leaf, 47% lost due to photons outside the 400–700 nm active range (chlorophyll uses photons between 400 and 700 nm, extracting the energy of one 700 nm photon from each one)
Increasingly frequent and severe heat waves in the Southwest are damaging some desert plants known for thriving in harsh conditions. Saguaro cacti and agave have both suffered in sweltering ...
The Sonoran Desert. The Sonoran Desert is a North American desert and ecoregion which covers large parts of the southwestern United States and of northwestern Mexico. With an area of 260,000 square kilometers (100,000 sq mi), it is the hottest desert in Mexico. The western portion of the Mexico–United States border passes through the Sonoran ...
