-Green plants manufacture food through the process of photosynthesis; the leaves contain chloroplasts which contain chlorophyll where photosynthesis take place;
-Light stage occurs in the granum; where chlorophyll traps light energy; which splits water into hydrogen ions and oxygen atoms/ photolysis; and ATP/ energy used in dark stage;
-Dark stage occurs in the stroma; where carbon (IV) oxide from the atmosphere; combines with hydrogen atoms to form simple sugars/ glucose molecules; which are converted into starch for storage;
