WebCAM plants demonstrate carbon fixing via crassulacean acid metabolism. CAM plants are desert succulents with stomata that open at night and fix carbon dioxide into organic acids such as malic acid and oxaloacetic acid. It is designed to decrease water loss. WebMar 24, 2024 · In most cases stomata open at day time and close at night. But there are some plants where reverse mechanisms occur for e.g. in xerophyte plants such as orchids, pineapple etc. because these plants live in dry conditions. Succulent plants are the plants that grow in dry conditions and follow CAM mechanism, also named as CAM plants.

Their stomata remain open during the night. … WebDec 21, 2024 · Stomatal closure in CAM plants during the day is linked with an increased concentration of intercellular CO 2 ( Ci) via the production of CO 2, owing to the decarboxylation of organic acids, rather than the effect of light on the stomatal response ( Osmond, 1978; Cockburn et al., 1979; von Caemmerer and Griffiths, 2009 ).
WebMar 17, 2024 · In CAM plants, stomata are closed in the day and open at night to minimize water loss during PEPC-mediated CO 2 fixation in the night. Then during the day, the CO 2-storing organic acids are decarboxylated to provide high concentration of CO 2 for C 3 photosynthesis with closed stomata.
