The following procedure dealt with a chromatogram. Then we sketched the leaf and labeled the blade and petiole. First we obtained a leaf from our instructor. The materials needed are: a dicot leaf, dissecting microscope or hand lens, and colored pencils. The next procedure dealt with the external leaf structure. Then we sketched the leaf and labeled the following structures: cuticle, epidermis, mesophyll, palisade parenchyma, spongy parenchyma, stomata, and guard cells. The materials needed are: colored pencils, a prepared slide of a leaf, and a compound microscope.Īfter obtaining the prepared slide of a leaf, we used a compound microscope to observe the leaf. Materials and methods: The first procedure dealt with the internal anatomy of a leaf. Also in this lab there is the internal and external anatomy of a typical leaf. This is the most important pigment in photosynthesis and there are also accessory pigments used in plants. Chlorophyll is a pigment in leaves that reflect green light waves. Then another spectrum was added called the electromagnetic spectrum (or a continuous spectrum) by James Clerk Maxwell this included: cosmic rays, visible light, x-rays, and radio waves.įor plants to use sunlight, they have to absorb it. These colors range from red at one end of the visible spectrum to the color violet at the other end. Sir Isaac Newton was an English physicist that used a light prism and demonstrated how white light contains varying colors. Now the sunlight ultimately powers the process of photosynthesis. Photosynthesis is a process where plants harness the sunlight they receive and they produce carbohydrates, as well as oxygen for living things and other plants. Plants have their own special way of using the ATP they produce. Introduction: Photosynthesis is a huge concept to learn and understand in the field of biology.
This lab covers the big components in photosynthesis including carbon dioxide intake, light consumption, and varying pigmentation.
It is a highly complex process that needs to be broken down in many steps to understand how it works. Lab Report: Understanding Photosynthesis Gen Biology Lab Abstract: This lab was called photosynthesis: understanding photosynthesis.
