Investigation into the photosynthetic activity of isolated chloroplasts from spinach beet to various light conditions. Introduction Chlorophyll‚ an important pigment in chloroplasts‚ is an essential component in photosynthesis; converting electromagnetic radiation from the sun into potential chemical energy. Photons excite electrons in chlorophyll which move through the electron transport chain‚ resulting in energy being stored in the bonds of ATP and NADPH. The flow of electron through the electron

Colours for living and learning The Universe is a magnetic field of positive and negative charges‚ constantly vibrating and producing electro-magnetic waves. Each of these has a different wavelength and speed of vibration; together they form the electro-magnetic sphere. White light when seen through a prism or water vapour splits into the colours of the spectrum. Of all the electro-magnetic sphere it alone can be seen. Radio waves‚ infra-red waves‚ ultra-violet waves‚ x-rays and gamma waves can

SCIENTIFIC REPORT ON THE EFFECT OF WAVELENGTH ON PHOTOSYNTHESIS Red wavelengths will increase the rate of photosynthesis to a greater degree than blue or green wavelengths and thus will be the most optimal for plant growth. This hypothesis will be tested under laboratory conditions using silver beet extracts and DCPIP under different wavelengths and assessing the photosynthetic qualities using a spectrometer at 605nm. Photosynthesis is the process by which the suns visible light (electromagnetic radiation)

thought that perhaps‚ the only colour in real life is white? White light is indeed the bearer of all colours. The colours we see are reflections bouncing off an object or are the light source itself. The light sources change and the colours with them. Colour is not a stable affair. Colour is light alone‚ but our experience is so direct that we trust our eye and believe that a colour is inherent to an object. Imagine living in a world where everything is white in colour! However‚ the world we live

The effect of differing wavelengths of visible light on the photosynthetic activity of Beta vulgaris Introduction Photosynthesis is a crucial biological process that occurs within the chloroplasts of plant cells where CO2 + H2O + Sunlight C6H12O6 + O2. The chloroplasts use light‚ an electromagnetic energy source‚ to produce food for the plant in the form of sugar molecules. During photosynthesis‚ the excited electrons from the light pass through proteins in the electron transport chain (ETC)‚ where

THE EFFECTS OF CIGARETTE SMOKE TO PHOTOSYNTHESIS Increased Carbon Dioxide Smoke of all kinds‚ including cigarette smoke‚ increases the amount of carbon dioxide where it is present (since smoke is itself produced via combustion). Plants use carbon dioxide to make sugars (during photosynthesis). Its increased abundance‚ therefore‚ makes it easier for the plant to obtain. Thus‚ smoking near a plant actually makes it easier for that plant to obtain much-needed carbon dioxide. Hampering Photosynthesis

Introduction: Photosynthesis can be defined as light energy being converted into chemical energy‚ which is a very important process for plants and other organisms. Light can be described in terms of light quantity and light quality. Both of these have an affect on photosynthesis. The more light a plant absorbs the more the plant is able to photosynthesize. This light is absorbed though pigments which have specific interactions with certain light waves (colors). The goal of my first experiment

The Effect of Different Light Colours on Plant Growth Dianne R. Calub Marshela Alpha B. Gesmundo BS-Environmental Science Prof. Jayson Antonio Chemistry Department January 04‚ 2012 Abstract The goal of this study is to learn how the colour of light affects photosynthesis‚ to identify the effects of different coloured lights on plant growth‚ and to identify the potential use of different light colours as a growth regulator. An experiment was performed with the help of 7 students. Mustard

Investigations in Light Intensity Change through Angular Displacement Guiding Question How does the intensity of light change as the angle of incidence to the light source increases? Prediction of Results Predict what you think will happen and what type of equation and graph might best fit the data representing the intensity of a light as the angle of incidence increases. Objective After completing this lesson‚ a student should be able to analyze light intensity striking a surface at varying
