AP Lab #5 Plant Pigments/Photosynthesis I. Identifying the Effects of Different Variables of Light and Carbon Dioxide on the Rate of Photosynthesis and Observing the Separation of Pigments Through Chromatography II. Introduction Plants have a variety of pigments‚ all of which absorb a different color of light. The three main pigments are chlorophyll a‚ chlorophyll b and carotenoids. Chlorophyll a is the primary plant pigment that absorbs red and blue light‚ which ultimately appears green to the human eye

Name Biology-Honors Teacher December 6‚ 2012 Photosynthesis Lab 1. Introduction: Light dependent reactions are the first phase of photosynthesis. It requires light to happen and happens in the thylakoid membrane in a chloroplast. The light energy is absorbed from the sun and converted into chemical energy. Which is then stored temporarily in ATP and NADPH. Hypothesis: I predict that the wavelength intensity will affect the rate of photosynthesis more than light intensity will. 2. Data:

An Experiment to Test the Effect of Temperature on the Rate of Photosynthesis in Green Algae Background Photosynthesis is an amazing process where plants are able to create their own food as well as oxygen using sunlight‚ carbon dioxide (co2)‚ and water. The part of the plant responsible for photosynthesis is the enzymes in the chlorophyll (structures that carry out photosynthesis located in leaves). Photosynthesis is the process of creating glucose. Water + Carbon Dioxide + Sunlight = Glucose

Investigation 5: Photosynthesis Problem: If the leaf disks are treated in a way you know increases the net rate of photosynthesis‚ should they start to float faster or slower? Why? Hypothesis: If the leaf disks were bathed in a red light source‚ then the rate of photosynthesis would increase than leaf disks that are bathed in a regular light source because chlorophyll absorbs red pigment and reflects green pigments. Therefore‚ shining a red light source onto the leaf disks would cause them

is called photosynthesis. This process is used by plants and other organisms for synthesis of lipids and amino acids or can be metabolized during cellular respiration to produce ATP. This process takes place in chloroplasts‚ which is a plastid that contains chlorophyll and involves two interlinked reactions‚ which are light dependent reactions and light independent reactions. Throughout our lab experiment‚ we focused on the affect access of light has on carbon dioxide during photosynthesis. Carbon

Lab Report: Understanding Photosynthesis Gen Biology Lab Abstract: This lab was called photosynthesis: understanding photosynthesis. It is a highly complex process that needs to be broken down in many steps to understand how it works. This lab covers the big components in photosynthesis including carbon dioxide intake‚ light consumption‚ and varying pigmentation. Introduction: Photosynthesis is a huge concept to learn and understand in the field of biology. Plants have their own special

on Photosynthesis Avalon Pernell‚ et al Abstract: The purpose of this lab was to determine how light affected photosynthesis‚ specifically the production of O2 bubbles. It was predicted that when the light was more intense the O2 bubble production will be high. Conversely‚ when the light was less intense the O2 bubble production will be lower. Basically the plant that is closer to the light will produce more bubbles than the plant that is placed farther away from the light source. In this lab the

measured in the number of bubbles produced by the plant. Three factors that influence the rate of photosynthesis can be adjusted in the simulator to determine how each of the factors affects the rate of photosynthesis.

Plant use some of the oxygen that they produce‚ but most of

Abstract Photosynthesis is a food making process for algae and plants. The photosynthesis process rate varies from different wavelengths and intensities of light. This lab will evaluate the optimal wavelengths and degrees of intensity during photosynthesis when chloroplast is exposed to light. The mixtures of DCPIP with water‚ PO4 buffer‚ and chloroplast will be prepared in a number of cuvettes. The cuvettes were tested individually at different wavelengths and intensities to find the optimal rate

Bio Block B Photosynthesis Lab 12/6/12 Introduction: Photosynthesis is affected by light intensity‚ water‚ and temperature. Plants grow more abundantly because the weather is warm. Carbon Dioxide given off by animals is consumed by plants that replace the oxygen animals take it. Experimentation will help understanding how plants are vital because of the oxygen they release. If leaf disks in the experiment release oxygen‚ they will undergo photosynthesis and float. If there
