Which of the following plants fixes carbon dioxide at night?
A
Sugarcane.
B
Cactus.
C
Oryza sativa.
D
Hibiscus rosa-sinensis.
Explanation: 

Detailed explanation-1: -In CAM plants stomata are open at night and they absorb carbon dioxide at night to reduce water loss during the daytime.

Detailed explanation-2: -Sansevieria Zeylanica, Snake Plant Considered highly efficient in oxygen production, Snake Plants are unique for their ability to produce oxygen and absorb carbon dioxide even at night.

Detailed explanation-3: -Breathing at Night Even though cacti get the carbon dioxide they need at night, photosynthesis still needs the sunlight. Cacti store the carbon dioxide they take in during the night in their cells in the form a chemical called malic acid. In CAM plants, carbon dioxide is only gathered at night, when the stomata open.

Detailed explanation-4: -Crassulacean acid metabolism, also known as CAM photosynthesis, is a carbon fixation pathway that evolved in some plants as an adaptation to arid conditions that allows a plant to photosynthesize during the day, but only exchange gases at night.

Detailed explanation-5: -When do the desert plants take up carbon dioxide & perform photosynthesis? Q. Plants use CO2 for photosynthesis during the day . But at night, they also respire, i.e., take in O2 and release CO2 into the air .
