Succulents are known to keep their stomata closed during the day to check transpiration. How do they meet their photosynthetic `CO_(2)` requirements ?

Text Solution

Verified by Experts

Succulent (water storing) plants such as cacti, euphorbias fix `CO_(2)` into orgnic compound using PEP carboxylase at night, when the stomata are open.
`PEP + CO_(2) to OA(A)`
`OA(A) to to to "Malic acid"`
The organic compound (malic acid) accumulates throughout the night and is decarboxylated during the day to produce `CO_(2)`.
