known as photosynthesis. When photosynthesis is functioning as it should‚ in its fullest capacity‚ all organisms benefit from it in some way. Furthermore‚ scientists aim to better understand the photosynthetic process to help enhance the efficiency and quality of life on Earth. By fully understanding the function of photosynthesis‚ some environmental adjustments can then be made to refine the photosynthetic process. In this lab specifically (Lab No. 7)‚ we isolated specific color wavelengths and recorded

Photosynthesis (pron.: /foʊtoʊˈsɪnθəsɪs/; from the Greek φώτο- [photo-]‚ "light‚" and σύνθεσις [synthesis]‚ "putting together"‚ "composition") is a process used by plants and other organisms to convert the light energy captured from the sun into chemical energy that can be used to fuel the organism’s activities. Photosynthesis occurs in plants‚ algae‚ and many species of bacteria‚ but not in archaea. Photosynthetic organisms are called photoautotrophs‚ since they can create their own food. In plants

How light intensity effects the Rate of photo synthesis. Aim The aim of my experiment is to find out how light intensity affects the rate of photosynthesis. Prediction I predict that as the light intensity increases that the rate of photosynthesis will increase in proportion‚ so for example if you increase the light intensity from 10cm away to 20 cm away form a stationary plant. There for the rate of photosynthesis will decrease proportionally with the distance of the light from the plant (in

Effects of Wavelength and Light Intensity on Photosynthetic Activity ABSTRACT The photosynthetic process of eukaryotes revolves around chlorophyll‚ the substance that give plants their green color. Plants convert light energy into chemical energy by means of photosynthesis. This experiment tests the reaction rates of a chloroplast suspension against variables of wavelengths and light intensity. Both a control and an experimental cuvette were exposed to a range of 450 to 750nm of light and varying

Plan I plan to investigate how light intensity affects the rate of photosynthesis in pondweed. The rate of photosynthesis will be measured by the number of bubbles given off (considering that oxygen is produced as a waste gas during photosynthesis). The light intensity is measured by the distance between the lamp and pondweed. Fair test: Fix: the amount of pondweed‚ the amount of water and sodium hydrogen carbonate solution in the test tube‚ the time allowed for each experiment Change: the

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:
Premium Photosynthesis Light Adenosine triphosphate
Abstract For this lab the rate of photosynthesis was analyzed upon plant leaves. A sample of a light exposed and a not-light exposed leave were used to clearly identify the role of sunlight in the process of producing and storing energy. Aim We are trying to find proof‚ to demonstrate the necessity of light and chlorophyll in the process of photosynthesis. Background Photosynthesis occurs in organisms which contain chlorophyll. It’s a process that involves the chloroplasts to synthesize glucose

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
Premium Photosynthesis Light Plant
Aim To work out how light intensity can affect the rate of photosynthesis. Hypothesis I think that the further away the light source is the smaller the rate of photosynthesis is. This is because there is a further distance for the light to each the plant in order for it to photosynthesise. Although the closer the light source is‚ the more photosynthesis‚ the light source could also kill or damage the Elodea (type of pondweed) because it could become too hot and denature its cells. But because
Free Carbon dioxide Oxygen Photosynthesis
Background Theory Photosynthesis: Plants require water from the soil‚ sunlight and carbon dioxide found in the atmosphere for growth and development. In the process of photosynthesis‚ carbon dioxide and water – in the presence of chlorophyll and light energy – are converted into sugar and oxygen‚ which is given off as a by-product. Generally‚ as sunlight increases in intensity‚ the rate of photosynthesis also increases [1]. This means greater food production within the plant. Many garden vegetables
