producer plant. The alternative hypothesis was that the rate of photosynthesis increases as the distance of the light decreases. This is because light energy can excites chlorophyll molecules more clorophyll mulcoulse as the distance of the light decreases. Photosynthesis is a process in which the energy of light is used to produce organic molecules. In this process Oxygen is released; therefore the rate of photosynthesis can be calculated by measuring the rate of oxygen production

PHOTOSYNTHESIS LAB Alyssa Wright VARIABLE: LIGHT INTENSITY AIM: to investigate the effect of light intensity (lux) on the amount of oxygen produced (number of bubbles) HYPOTHESIS: I predict that the rate of oxygen produced increases‚ as the light intensity increases‚ but only to a point. I predict this will happen because the plant will have enough carbon dioxide and water to keep up with the amount of light that there is. When there is less light intensity‚ photosynthesis will happen

plants‚ as rubisco is reduced inefficiently in C3 plants because of higher atmospheric CO2 concentrations. 3.5 PHOTOSYNTHESIS AND THE ENVIRONMENT Section 3.5 Questions (Page 178) Understanding Concepts 1. 2. Irradiance limits the overall rate of photosynthesis under low light conditions. As irradiance increases‚ photosynthesis begins. C4 plants generally exhibit higher rates of photosynthesis when compared with C3 plants because of the fact that although photorespiration rates increase with increasing

and chlorophyll. This process of plants making their own food with sunlight and chlorophyll is called photosynthesis. The photosynthesis process involves sunlight‚ sugar‚ and chlorophyll. Chlorophyll is called a photoreceptor. It is found in the chloroplasts of a plant cell that is within green plants‚ and is what gives green plants their green color. Chlorophyll has a special role in photosynthesis. Chlorophyll molecules absorb light energy. Chlorophyll is a complex molecule‚ which has lead to a

BIO 101 Lecture Notes for Respiration‚ Fermentation‚ and Photosynthesis Respiration During aerobic respiration‚ glucose is completely oxidized (all H’s removed) leaving CO2 as an endproduct. The H’s are taken by coenzymes (NAD and FAD) to the electron transport chain. There the energy is drained from the hydrogen electrons and the energy is used to make ATP. The H’s are ultimately accepted by O2 to make H2O as an endproduct. Respiration occurs in three major stages: 1) Glycolysis
