During the day, desert plants use malic acid for ____
A
Oxygen
B
Hydrogen
C
Carbon
D
Breathing
Explanation: 

Detailed explanation-1: -When there stomata are opened at night carbon dioxide is absorbed by the plant and is stored in the form of intermediate product called malic acid. This malic acid breaks during the day to release carbon dioxide and hence, desert plants can perform photosynthesis even though there stomata are closed during the day.

Detailed explanation-2: -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.

Detailed explanation-3: -The desert plants which grow in semi-arid conditions fix atmospheric CO2 to form malic acid in the dark. These plants accumulate organic acid intermediate during the night to be used during the daytime.

Detailed explanation-4: -In desert plants, the stomata are open amid night. Amid night, desert plants assimilate carbon dioxide and shape a transitional. At that point amid daytime when the stomata are shut to avoid loss of water, they utilize this put-away carbon dioxide to perform photosynthesis.

Detailed explanation-5: -These desert plants take in carbon dioxide during the night time or when the temperature is cooler because during the day the stomata are closed to prevent transpiration or water loss.
