(Add these words to the back of the Chloroplast coloring worksheet.)

Group 1 = plants : chloroplast : photosynthesis : anabolic : autotroph.

Group 2 = animals : mitochondria : cellular respiration : catabolic : exothermic : heterotroph.

(Also add this paragraph describing the calvin cycle)

The Calvin cycle begins when one molecule of carbon dioxide is added to each of three 5-carbon (RuBP) molecules to form three 6-carbon molecules. Each of the 6-carbon molecules splits in half to form two 3-carbon molecules of PGA. The stroma "spends" or depletes molecules of ATP and NADPH to energize the 3-carbon molecules. This forms six molecules of PGAL. One of the newly formed PGAL molecules leaves the Calvin cycle to become half of a new sugar molecule. The remaining five PGAL molecules rearrange to form the beginning three 5-carbon (RuBP). This rearrangement causes the cell to repeat a second time to complete a whole six carbon sugar.
