Succulents are known to keep their stomata closed during the day to check transpiration. How do they meet their photosynthetic CO2 requirements?
Answer :
Succulents are known to keep their stomata closed during the day to check transpiration. So in order to meet their photosynthetic CO2 requirements, they fix CO2 into organic compound using PEP carboxylase at night, when the stomata are open.
PEP + CO2 --→ OAA
OAA --→ --→--→Malic Acid
