317. Mark incorrect statement w.r.t. CAM cycle 
(1) All CAM plants are succulent 
(2) CAM plants are not as efficient as CA plants
(3) Primary and final CO2 fixation are separated 
by space
(4) Primary and final CO2 fixation are separated 
by time 


 

 

Dear student,
The incorrect statement is 3, Primary and secondary CO2 fixation are separated by space.
The main difference between C4 and CAM plants is the way they reduce the photorespiration. C4 plants relocate the CO2 molecules to minimize photorespiration while CAM plants is specific in time when to extract CO2 from the environment. They capture CO2 at night when the environment is much cooler and stores the concentrated CO2 as malate. This is then released back during the day to be utilized in photosynthesis. Stomata remains closed during the day to prevent water loss.

Regards.
