Source of `CO_(2)` for photosynthesis during day in CAM plant isA. 3-P

1.	Source of `CO_(2)` for photosynthesis during day in CAM plant isA. 3-PGAB. Malic acidC. Oxalo-acetic acidD. Pyruvate
Answer» Correct Answer - B In CAM plants there is no kranz anatomy, but there occurs dark acicification, i.e., during night malic acid is formed. This malic acid breaks up into `CO_(2)` and pyruvic acid in day time and `CO_(2)` released is utilized in C-3 cycle.
