Photosynthesis is the process in plants and some algae that convert energy from the light to chemical energy, stored in the bonds. The overall reaction is: 6CO2 + 6H2O (+ light energy) → C6H12O6 + 6O2 In order to make sugar plants need light energy, carbon dioxide and water. The products are also water, oxygen in the air and carbohydrates. This is the main source of the O2 humans breathe, and therefore deforestation is a significant concern nowadays. Photosynthesis occurs in the chloroplasts, using chlorophyll, the green pigment. It occurs in plant leaves, and little in stems. The leaf of the plant consists of the upper and lower epidermis, the mesophyll, the stomata and the veins. The epidermal cells do not contain chloroplasts, hence photosynthesis doesn’t occur there. They protect the rest of the leaf. The stomata are little holes, situated in the lower epidermis and are for air exchange, CO2 goes in and O2 out. The mesophyll cells have chloroplasts and photosynthesis occurs there. The chloroplast includes the outer and inner membranes, stroma, thylakoids of grana and intermem...
