Blog 5 Explain the difference between C3,C4, and CAM plants in terms of their photosynthesis.

C3 plants are used in the Calvin cycle to incorporate CO2 into organic material to form three-carbon compounds. C3 plants produce less sugar on hot dry days because a low level of CO2 in the leaf does not give enough "food" for the Calvin cycle to take place.

For some plant species, different modes that make photorespiration shorter and for effective in hot climates. The two most important factors for this to happen are C4 and CAM plants.

C4 plants give the Calvin cycle an alternate version of carbon fixation that forms a four-carbon compound as its first product. Unlike C3 plants C4 plants are adapted to hot dry climates. They maintain a Co2 concentration in the bundle sheath that favors photosynthesis over photorespiration. The CAM pathway is similar to the C4 path way because carbon dioxide is first incorporated into organic intermediates before it enters the Calvin cycle. They way they are different is that in C4 plants caron fixation are seperated from the Calvin cycle and in CAM plants the two steps take place within the same cell.
