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

C3 Plants:

• normal plants the doesn't have to face harsh environment
• only opens their stomata during the day time
• regulates the Light reaction and Calvin Cycle normally

C4 Plants:

•  has 2 different cells that C3 plants and CAM doesn't have: Mesophyll Cells and bundle sheath  cells
• the plant uses C4 carbon fixation in which carbon is attached to the phophoenolpyruvic  in the Mesophyll Cell ceating a four carbon compound
• then in the bundle sheath the four carbons is then decomposed into carbon and pyruvate and to be used for the C3 pathway
• the carbon in the C3 pathway is turned into glucose and the pyruvate is sent back into the Mesophyll cell
• afterward the pyruvate is turned back into a phophoenolpyruvate  with the help of the ATP.

CAM Plants:

• They only have one cell
• their stomata is only open during the night, closed during the day (opposite of the C3 plants)
• Carbon inhaled by the plant and oxygen is exhailed
• they usually have the characteristics of small and has small or thin leaves to store water, these plants are most likely found in the destert and any other harsh biomes.
