Effect of Extreme Temperatures on the Rate of Photosynthesis 2. Jeffrey Xia 2. Abstract A previous lab in which we conducted‚ tested whether or not the light intensity had an effect on the rate of photosynthesis. We concluded that light intensity did possess an effect on the rate of photosynthesis – the closer the experimental plant units were to the light source‚ the more experimental plant units exhibited the effect of gas exchange in photosynthesis. Therefore‚ in this lab‚ we desired to test

Answers to Photosynthesis Practice AP Biology 1. Draw a picture of the chloroplast and label the stroma‚ thylakoid‚ thylakoid lumen (space)‚ inner membrane‚ outer membrane. 2. Using 18O as the basis of your discussion‚ explain how we know that the oxygen released in photosynthesis comes from water. When the oxygen in water has the radioactively labeled oxygen‚ the gas released from photosynthesis also has the labeled oxygen. This shows that the oxygen gas given off during photosynthesis comes from

Truesdell AP Biology Period 5 2 October 2013 CHAPTER 7 STUDY GUIDE AN OVERVIEW OF PHOTOSYNTHESIS Autotrophs are plants that can feed themselves by making their own food. Photo-autotrophs are organisms that produce organic molecules from inorganic molecules using the energy of light. Producers are when plants make their own organic molecules. A redox reaction is oxidation and reduction. Photosynthesis takes water and carbon dioxide to make glucose and oxygen. Cellular respiration takes glucose

affect Photosynthesis? Introduction: Photosynthesis is the process by which green plants and some other organisms use sunlight to synthesize foods from carbon dioxide and water. Photosynthesis in plants generally involves the green pigment chlorophyll and generates oxygen as a byproduct. It produces sugar and other organic compounds such as lipids and proteins. The sugars are then used to provide energy for the organism. Light reaction is the series of biochemical reactions in photosynthesis that

Because a successful revolution is determined to be a success if the initial‚ primary goals of the revolution are achieved‚ and because the French Revolution failed to attain many of its fundamental objectives

The light reactions of photosynthesis contain two photosystems‚ two electron transport chains‚ and ATP synthase. These parts are embedded in the thylakoid membranes of a chloroplast. The photosystems contain a collection of chlorophyll molecules. Chlorophyll‚ which is the green pigment of leaves‚ absorbs light energy that excites electrons to a higher energy level. Energized electrons from photosystem I are passed down an electron transport chain and added to NADP+ to form NADPH. Electrons from photosystem

Introduction: Photosynthesis is a process to which some autotrophs such as plants produce their own food. It has two stages or reactions light-dependent and light-dependent reactions. The light dependent reactions are the first stage‚ where energy from sunlight is captures in Photosystem 2 and then 1‚ the electrons generated in Photosystem 1 then moves along the electron transport chain. The moving of electrons causes a hydrogen ion gradient that is used in the final step to produce ATP‚ by the

Determination of rate of photosynthesis INTRODUCTION Photosynthesis is the major process by which light from the sun is captured by plants‚ algae and some bacteria to produce energy. It is a process in which light energy is converted into chemical energy which is then stored in sugars. Photosynthesis occurs in two stages‚ light-dependant reactions and light-independent reactions. In light-dependent reactions the chlorophyll traps light energy which is then used to excite electrons and split water

The classroom light was our control cup during the lab. Before we conducted our experiment‚ the class learned about the photosynthetic process of‚ not only spinach discs‚ but plants in general.
