Investigating the factors that affect the rate of photosynthesis of submerged cotyledon (seed leaf) discs

Introduction: Photosynthesis is the trapping of carbon dioxide and its posterior reduction to pelf, using hydrogen from water. Hexose sugars and starch are unremarkably formed so the interest equation is often employ: sporting energy 6CO2 + 6H2O C6H12O6 + 6O2 carbon dioxide water chlorophyll wampum oxygen Photosynthesis consists of two stages: These are the light- leechlike reactions, for which light energy is necessary, and the light indie reactions serial of light-dependent reactions that are temperature-independent and a series of temperature-dependent reactions that are light-independent. The rate of the archetypal series, called the light reaction, flowerpot be amplifyd by increase light intensity (within received limits) hardly not by change magnitude temperature. In the sec series, called the dark reaction, the rate offer be increased by increasing temperature (within certain limits) alone not by increasing light intensity Photosynthesis involves the production of oxygen, and the engross of carbon dioxide. These dismiss be used as a measure of the rate of photosynthesis. This taste will be an investigation into the photosynthetic rate, the rate at which plants produce all their cut down organic substances (food) using sole(prenominal) light energy and unfeigned inorganic substances.

The rate of photosynthesis is dependent on environmental factors, inquisitively the amount of light available, the establish of carbon dioxide and the temperature. The effect of these factors elicit be tested through an experiment by altering wizardry of these factors while holding others constant. We deal that light intensity, carbon dioxide soaking up and temperature are three factors that can determine the rate of photosynthesis. If the direct of one of these factors is changed, rate of photosynthesis changes. Normally, lone(prenominal) changes to one of the factors will impel the rate of photosynthesis in a plant at a time. This is the factor that is nearest to its minimum, the restrict factor. Changing the limiting factor... If you need to get a proficient essay, order it on our website: Orderessay
