Question

Succulents and want to keep their stomata is closed during the day to check transportation how do they meet their photosynthetic carbon dioxide requirements?

Answer 1

⭐⭐⭐⭐⭐⭐⭐⭐⭐⭐⭐⭐⭐⭐

➡️ such plants carbon dioxide to form organic acids using PEP carboxylase at night stomata open during night in succulents decarboxylation occur during sunlight CO2 gas liberated is fixed by Calvin cycle

Answer 2

Explanation:

➡️ Succulents pick up CO2 during night when their stomata are open. They like C4 Lance fix it in oxaloacetate, through carboxylation of PEP with the help of PEP carboxylase. Oxaloacetate being unstable is converted into malic acid. Malic acid is stored. During the time when the stomata are closed, malic acid is decarboxylase to release CO2. The same is fixed through Calvin cycle.

Hope it helps!!☺️
