Photosynthesis is a form of a chemical reaction that transforms energy from the sun in to a chemical energy‚ a carbohydrate known as glucose. Only plants are able to use this process to make their own food. This chemical reaction takes place in Chloroplasts‚ cells that are found in any green part of the plant. Chloroplasts are in green fragments of the plants because it contains a green pigment called chlorophyll. Although Photosynthesis can occur in any green portion of a plant‚ it mostly occurs

Introduction Plants use a process called photosynthesis to covert energy from the sun into energy they can use for their activities. The plant’s chloroplasts‚ along with water‚ carbon dioxide‚ and light are the essential elements required for photosynthesis to take place. The “photo” part of photosynthesis is in reference to the fact that the process requires light. The simplest form of the photosynthesis equation is: H2O + CO2 ----light----> (CH2O)N + O2 As shown in the equation‚ photosynthesis produces

Introduction The purpose of this lab is to determine which pigments in a plant support or effect photosynthesis‚ based on starch production‚ which wavelengths of light are involved in photosynthesis‚ and identify plant pigments found in a plant leaf by means of paper chromatography. Life on Earth is dependent entirely on the energy from the Sun‚ not only to keep the planet at a suitable temperature but also to provide the energy required to sustain life. The energy of the Sun‚ in the form of

Josh P. AP Biology 12-10-13 Lab Writeup The Effect of Transformation of pGLO in Bacteria Background/Objectives/Hypothesis: Genetic transformation is a process that primarily is inserting new DNA into an organism to change that organism’s trait. This process has many useful benefits when used correctly in different organisms. In this lab‚ bacteria was transformed by inserting DNA for Green Fluorescent Proteins. The DNA for these proteins were taken from bioluminescent jellyfish Aequorea

wavelength of light on the rate of photosynthesis was investigated in this experiment. The results from Figure 13 suggest that white light‚ containing all wavelengths of coloured light‚ has the highest rate of photosynthesis. Purple light had the second highest efficiency‚ followed by blue‚ red‚ and yellow light. Green light was significantly less efficient‚ producing the second lowest pH reading (Figure 14). The samples exposed to no light had the lowest rate of photosynthesis. The hypothesis that white

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

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

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.

Lab 1 Diffusion‚ Osmosis‚ and Water Potential of Glucose Problem: What effects will glucose have on diffusion‚ osmosis‚ and water potential? Background: All living things have certain requirements they must satisfy in order to remain alive. These include exchanging gases (usually CO2 and O2)‚ taking in water‚ minerals‚ and food‚ and eliminating wastes. These tasks ultimately occur at the cellular level‚ and require that molecules move through the membrane that surrounds the cell. There
