Observation The authors of this experiment‚ The Effects of some Inhibitors on the Rates of Photosynthesis and Respiration by Chlorella‚ knew that the rates of photosynthesis and respiration of many plants are affected by an adding chemicals. (Yaun and Daniels‚ 2000) The authors in this experiment would like to know in which ways different inhibitors affect photosynthesis and respiration distinctly. Objectives How certain inhibitors affect photosynthesis How certain inhibitors affect respiration

Based off the results from this lab the student was able to determine and have an overall better understanding of the variables that affect the rate of photosynthesis in a plant. The first variable the student tested in the lab was 30cm of light with CO2 present. The student started this trial with all 10-leaf disks and timed how many leaf disks came up every minute for 15 minutes. One minute into the trial and the student recorded that no leaf disks had yet to rise to the top of the solution. At

Both photosynthesis and cellular respiration are the main pathways of energy transportation in organisms. However‚ the reactants and the products are exact opposites in photosynthesis and in cellular respiration. In photosynthesis‚ cells take in carbon dioxide (CO2) and water (H2O) by absorbing energy from the sun‚ and then the cells release oxygen (O2) and store glucose (C6H12O6). The formula of photosynthesis is: Light energy 6CO2+6H2O → C6H12O6+6O2

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

In conclusion‚ one can determine how photosynthesis is impacted by light intensity through the experimentation on ivy leaf disks in a bicarbonate solution. The function of the sodium bicarbonate in this experiment was to provide a sufficient amount of carbon dioxide (CO2) for the photosynthesis process to occur. Without CO2 or any of the other necessary reactants‚ glucose nor oxygen cannot be produced. The leaves rise and sink due to photosynthesis occurring in the plant cells. As the carbon from

and the rate of photosynthesis and instead it starts relatively high then decreases and increases again. The colour red gives the highest rate of photosynthesis (89 bubbles per minute) with blue giving the second highest rate of photosynthesis (70 bubbles per minute)‚ and yellow giving the third highest rate of photosynthesis (64 bubbles per minute) and green with by far the least (44 bubbles per minute). Although‚ we can see no direct correlation between the rate of photosynthesis and the wavelength

Light Absorption by Photosynthetic Pigments in Silver Beet Abstract The aim of the experiment was to determine the absorption of differing wavelengths of light by individual pigments in the vegetable silver beet. Pigments were extracted from silver beet leaves and separated into chlorophyll a‚ chlorophyll b‚ and carotene via chromatographs. Chlorophylls were then separated and an absorption spectra created using results obtained from a spectrophotometer. It was clear there were two distinct peaks

Photosynthesis notes -sunlight brings energy to Earth -the energy in sunlight is packaged in photons -the photosystems in the thylakoid membrane capture photons -pigments in the photosystems have an antenna complex that actually grabs the photons -chlorophyll b captures the photons and transfers the energy to chlorophyll a (the reaction center) -when the reaction center receives the energy it donates an electron -the donated electron will move down the electron transport system (ETS) -ETS

An experiment to investigate the effects of carbonate concentration in water on the rate of photosynthesis. Aim: The aim is to investigate how increasing carbonate in water can affect the rate of photosynthesis. Introduction: The rate of photosynthesis can be increased or decreased in many different ways. For example‚ by adding substances like alkaline or salt to the water‚ you can increase or decrease the acidity or basics‚ if the water has too much acidity‚ it can often delay the rate of photosynthesis
