Cii: Interpretation of Data The data above collected from a lab experiment to determine the average amount of leaf discs floating when exposed to different frequencies this gives us results to see determine the rate of photosynthesis under various lighting conditions. Photosynthesis is a process that occurs in all plants, some bacteria, particular algae and few other species. This is because these organisms’ have a unique ability to produce their own food from the raw materials gathered by the environment this process is called photosynthesis. These organisms are at the beginning of the food chain. During photosynthesis light energy from the sun is absorbed by green plants. The energy is applied to convert carbon dioxide CO2 and water …show more content…
The set of wavelengths absorbed by a pigment is its "absorption spectrum". Certain wavelengths are absorbed; others are reflected; when certain wavelengths are reflected, color is produced. This is the reason behind why plants are green. Because the main pigment chlorophyll absorbs all colors in the visible light spectrum but green. Plants also feature accessory pigments which are chlorophyll b and carotenoids. These different pigments absorb different wavelengths/frequencies of light except green. The use of accessory pigments is to capture and absorb most of the wavelength which is energy supplied from the sun. These pigments/molecules are located in membranes of thylakoids. In these thylakoids pigment pigment and enzymes are arranged in photosystems. Including Photosystem I and Photosystem II. Red and Blue wavelengths of light is the most effective because when a pigment absorbs a photon of light, it energizes producing excess energy causing the electron to be bumped out of orbits to a higher energy level or energy orbit away from their nucleus. The following diagram shows this process of a photon with the right amount of energy. This also shows why different pigments absorb different wavelengths of
