Introduction The purpose of this lab is to determine which pigments in a plant support or effect photosynthesis‚ based on starch production‚ which wavelengths of light are involved in photosynthesis‚ and identify plant pigments found in a plant leaf by means of paper chromatography. Life on Earth is dependent entirely on the energy from the Sun‚ not only to keep the planet at a suitable temperature but also to provide the energy required to sustain life. The energy of the Sun‚ in the form of

and I conducted an experiment about the photosynthetic rate of spinach discs. We were hypothesizing that if we place all 6 individual cups underneath a different color of light‚ the spinach discs that produce enough oxygen will have the highest amount rise‚ which will show us the optimal color of light for photosynthesis. These different colors of light included blue‚ red‚ green‚ fluorescent‚ regular light‚ and classroom light. The classroom light was our control cup during the lab. Before we conducted

Photosynthesis Background Do you know what is the most important process that sustains life? Photosynthesis‚ that is the correct answer! Photosynthesis‚ is known as the process to produce plant food. But‚ how does is the life exist on the planet we call our home‚ Earth? Photosynthesis is a process that we know that allows water‚ carbon dioxide‚ and some mineral salts along with the light from the sun to make glucose (sugar). During the process‚ the root sytem of the plant takes in elements
