Abstract The undersides of three pieces of spinach leaves were painted with clear nail polish. Clear tape was placed onto the area and carefully removed to get the leaf impression. The impression was viewed under the microscope and the amount of stomata was recorded in the data table.
Introduction
Photosynthesis is the conversion of unusable light energy to usable chemical energy inside chlorophyll. This energy is stored in sugar. The chemical equation for photosynthesis is 6CO2 + 6H2O ------> C6H12O6 + 6O2. Photosynthesis supports almost every organism in some way. The sugar that chemical energy is stored in can be transformed into ATP, the fuel that powers the majority of living things, through cellular respiration. (Farabee, 2007) Leaves have a waxy waterproof outer coating called the epidermis and a very thin layer called the cuticle. This layer contains guard cells, which expand and contract through photosynthesis. This action allows the stomata, or pores, to open and close. The stomata controls transpiration and the passage of oxygen and carbon dioxide through the leaf. Interior leaf tissue is called mesophyll, and this is where chloroplasts can be found. They are found mainly in the columnar cells near the surface called palisade parenchyma, and the irregular cells beneath called spongy mesophyll parenchyma. Water is transferred to the leaves through veins and a tissue called xylem. (“Leaf Structure and Function,” 2011) The chloroplasts of a leaf are the main…
