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.
About 8,100 plant species use C 4 carbon fixation, which represents about 3% of all terrestrial species of plants. [ 27 ] [ 28 ] All these 8,100 species are angiosperms . C 4 carbon fixation is more common in monocots compared with dicots , with 40% of monocots using the C 4 pathway [ clarification needed ] , compared with only 4.5% of dicots.

The C4 grasses have a photosynthetic pathway, linked to specialized Kranz leaf anatomy, which allows for increased water use efficiency, rendering them better adapted to hot, arid environments. [13] The C3 grasses are referred to as "cool-season" grasses, while the C4 plants are considered "warm-season" grasses. [8]: 18–19
The simpler C3 cycle which operates in most plants is adapted to wetter darker environments, such as many northern latitudes. [citation needed] Maize, sugar cane, and sorghum are C4 plants. These plants are economically important in part because of their relatively high photosynthetic efficiencies compared to many other crops. Pineapple is a ...
Hims compiled a list of the top 25 U.S. counties for dating based on the number of single households, median age, restaurant volume per capita, and proximity to a major metropolitan area.
C4 plants have developed the C4 carbon fixation pathway to conserve water loss, thus are more prevalent in hot, sunny, and dry climates. [20] These plants differ from C3 plants because CO 2 is initially converted to a four-carbon molecule, malate, which is shuttled to bundle sheath cells, released back as CO 2 and
