AFFECTING THE RATE OF PHOTOSYNTHESIS. Introduction Photosynthesis is a chemical reaction which takes place inside the green plants (plants with chlorophyll‚ a pigment found in chloroplasts which causes the colour of the plants and it is the main photosynthetic pigment) and light energy is converted into chemical energy. Carbon dioxide‚ water and sunlight is transformed into sugar an oxygen‚ which later will be used as energy for the plant. The chemical equation of photosynthesis is:

Egg-speriment Write-up Part 1- Purpose: Why did we do the experiment? The purpose of this experiment was to understand how osmosis works and that the cell membrane is selectively permeable. Osmosis is the diffusion of water molecules through a selectively permeable membrane. Many cells cannot function without adequate water‚ so cells depend on osmosis. When a cell is selectively permeable‚ it means some substances can pass through while others can’t. Many examples of these were shown throughout

Transpiration Lab Write-up. Introduction Transpiration is the evaporation of water from plants. It’s not simply a hazard of plant life but it’s the engine that pulls water from the roots to cool the leaf and supply photosynthesis. The concentration of water vapor in the atmosphere is lower than that in the leaf. Because of this difference‚ water vapor diffuses from the spaces of the leaf‚ through the stomata in the epidermis. Stomata are in the lower epidermis; the lower surface receives less

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 ATP and NADPH are produced. The CO2 absorbed by the plant are then fixed into

If i increase the intensity of the rate of photosynthesis would drastically increase which is the light bubbles would be emitted in the jar in one minute because of the fact that the more photons of light that fall on a leaf then more chlorophyll molecules would be ionised and the more ATP and NADPH are generated If i increase the intensity of the rate of photosynthesis would drastically increase which is the light bubbles would be emitted in the jar in one minute because of the fact that the more

I am investigating how the rate of reaction differs when we change the concentration of Hydrochloric Acid whilst reacting with Magnesium. The rate of reaction is explained by the Collision Theory. This theory explains how various factors affect the reaction rates and how chemical reactions occur. The 4 factors of the Collision Theory are: • Temperature • Concentration • Surface area • Catalyst I am investigating how different concentrations of acids affect the rate of reaction. However I must

to determine the points of the highest absorbance and transmittance percentages. (Hickey‚ Mary Kay). For this experiment‚ a Bausch and Lomb Spectrophotometer was used. Often objects appear colored because of their absorption of light within regions of the visible spectrum. The color of light we can see is composed of the wavelengths that the object did not absorb. Photosynthesis in plants takes place in organelles called chloroplasts. Chloroplasts contain a number of coloured compounds‚ known

Chemistry Lab Write-Up Title: Paper Chromatography of Powdered Beverage Mix Purpose/Objective: The purpose is to be able to use liquid chromatography to separate dyes in a powdered beverage mix‚ calculate the Rf values for each dye‚ and rank the polarity of each dye present. Hypothesis: If we are to use the liquid chromatography to investigate the different dyes‚ then I think the different dyes will come up having different polarities and Rf values. Procedure/Method: Draw a line across

2-ethanoylhydroxybenzoic Acid in an Aspirin Tablet Introduction and Aim: An Aspirin tablet is an analgesic; therefore the purpose is to relieve pain and due to it also being an antipyretic its other tenacity is to lower the body temperature. An experiment was carried out on the basis of calculating the percentage of 2-ethanoylhydroxybenzoic Acid in aspirin tablets hence 4 commercial tablets were taken to determine its purity using a known volume of standard sodium hydroxide‚ due to the fact that
