Solution

Succulent plants

● Succulents keep their stomata closed during the daytime to prevent the loss of water through transpiration. This is because these plants grow in dry and xeric conditions.
● They have adapted themselves to open their stomata during the night.
● They fix atmospheric $C O_{2}$ during the night in the form of malic acid.
● This malic acid is then acted upon by certain enzymes in the day to synthesize glucose.
