MeSH definition : A water-saving mode of photosynthesis whereby CARBON DIOXIDE (CO2) taken up during
the nocturnal opening of stomata (STOMATA, PLANT) is fixed to produce malate, which
is accumulated in VACUOLES overnight as malic acid and subsequently decarboxylated
during the day with the resulting CO2 produced being re-fixed by RUBISCO and re-assimilated
through the REDUCTIVE PENTOSE PHOSPHATE CYCLE. CAM photosynthesis is found mostly
in plants in arid areas, but it is also found in aquatic plants and orchids.;
