Respuesta :
The most likely reason for the cacctus to use this special photosynthetic process is to conserve water
Correct answer: CAM Photosynthesis
The CAM Photosynthesis stand for Crassulacean acid metabolism, which takes place in the mesophyll of the plants that are adapted to dry environments such as pineapple and cacti.
In such plant opening of stomata takes place during the night and Calvin cycle occurs during the day. The stomata of the leaves remain closed during the day in order to reduce evaporation and open at night to gather carbon dioxide.
