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

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

photosynthesis in Ivy disks Background: All plants are autotrophs meaning they create their own food from inorganic chemicals in their surrounding. In the case of food‚ plants use CO2 to create glucose. In addition to the inorganic chemicals‚ plants use sunlight to create their glucose because the photosynthesis reaction is endothermic. The rate of this reaction‚ in turn‚ can be measures. And this lab uses oxygen which is created as a result of the photosynthesis reaction. Since

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

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

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 our experiment‚ the class learned about the photosynthetic process of‚ not only spinach discs‚ but plants in general. As I did more research on photosynthesis‚ the Calvin Cycle‚ wavelengths and pigments required for a proper equation

Photosynthesis is the process by which light energy is used to convert inorganic compounds into organic substances with the subsequent release. There are many factors which can have an effect on the process of photosynthesis; in this laboratory experiment‚ the focus lies on carbon dioxide (CO2) availably and its effect on photosynthesis. By understanding the component that affect the rate of photosynthesis‚ one can do work to try and increase the rate of photosynthesis. The purpose of this laboratory

can also be called the rate limiting factor as it affects the rate of photosynthesis. Introduction Photosynthesis is an essential process by which plants make their food in order for growth and respiration to happen. Carbon dioxide water and light combine to manufacture food which comes in the form of glucose for use. Light is a very important aspect in plant growth as with light the light dependent reaction in photosynthesis is able to take place. In this process light is used to break down water

Conclusion I predicted that if the decolorization of DPIP is caused by photosynthesis and not cell respiration and spinach extract containing chloroplasts and mitochondria is incubated with DPIP‚ then the rate of DPIP decolorization should be higher if in bright light verses dark light because DPIP is reduced by photosynthesis and not by the mitochondria or any other cellular function. If DPIP was only decolorized by chloroplasts‚ then the percent transmittance of chloroplast suspensions would be

Photosynthesis and respiration are both processes that are necessary for the survival of organisms. However‚ in numerous ways these two processes are very diverse as they are responsible for distinct necessities. Therefore they both have similarities and differences. One major difference between the two is that photosynthesis takes place completely in plants while respiration occurs equally in plants and animals. Nevertheless to understand Photosynthesis and respiration‚ we need to understand what
