Plants photosynthesize in order to produce sugar and oxygen, which, in turn, gives the plant energy. Photosynthesis usually tends to occurs more when more chlorophyll are present in the leaves. When the leaves are exposed to light, the process of photosynthesis begins. The more light the plant is exposed to, the quicker the rate of photosynthesis will occur. Altering the amount of carbon dioxide given to the plant can also alter the rate at which photosynthesis occurs. Photosynthesis is a process plants undergo that uses water and carbon dioxide gas in the presence of light energy to produce glucose and oxygen gas. This is represented by the formula: 6CO2 + 12 H2O -> C6H12O6 + 6 O2 + 6 H2O. Photosynthesis happens within the chloroplasts of a plant cell. Inside each cell are pigments that absorb the necessary light to carry electrons to the photosystems and capture the light energy. Chlorophyll a and b are the primary pigments. They absorb red and blue wavelengths of light and reflect green and yellow wavelengths. Photosynthesis takes place inside the chloroplasts, which are in the cells in the mesophyll, or the middle layer of the leaves. The mesophyll is surrounded by the epidermis, which protects the leaves, and the cuticle, a layer of wax on the surface of a leaf that prevents water loss. At the bottoms of leaves are the stomata, where oxygen, carbon dioxide, and water move in and out of the leaf. Spinach leaves, in particular, are thin, which helps maximize sunlight…
