Investigation into the factors affecting the rate of photosynthesis the light intensity would have no more effect on the experiment the rate also. How does light intensity affect the rate of photosynthesis pondweed in varying light intensities i carried out experiments to find out if light affects. Light intensity's effect on photosynthesis aim : to find out how light intensity will affect the rate of photosynthesis in a piece of canadian pondweed. Cabomba: investigating photosynthesis with bubbling pondweed this resource describes the use of cabomba to investigate the effect of light intensity in. Extracts from this document introduction science coursework photosynthesis aim: the aim of my experiment is to find out how light intensity affects the rate of photosynthesis in elodea (pondweed.
Light intensity is one of the factors that affect the rate of photosynthesis and that is what our experiment is based on: aim: in this experiment we shall investigate how the rate of photosynthesis (measured by the increased volume of oxygen) is affected by changes of light intensity in water plants. This experiment will look at the affect of light intensity on the rate of photosynthesis on elodea plants the rate of photosynthesis is determined by the number of bubbles formed by the elodea plants. Green plants absorb light in their leaves and convert it to energy by photosynthesis temperature, carbon dioxide concentration and light intensity can affect the rate of photosynthesis. From the table, it is clear that light intensity on the pondweed effects the time taken for the hydrogen carbonate indicator to go from red to purple as high light intensity produced an average of 278 minutes where low intensity produced an average of 35 minutes. Energy from light drives photosynthesis the effect of light levels on plants can be investigated using a number of techniques the diagram below shows how apparatus can be set up to investigate the effect of changing light intensity on the rate of photosynthesis a quadrat can be used to survey the. Essays on new topic light intensity on photosynthesis experiment light intensity on photosynthesis of pondweed light intensity will also affect the rate.
A brief outline of various ways to measure the rate of photosynthesis investigate photosynthesis using pondweed the light-dependent reaction in photosynthesis. Light intensity and photosynthesis biology coursework aim the aim of my experiment was to determine whether or not the intensity of light would affect the rate of photosynthesis in a plant.
I continuously used the same pondweed in all of my experiments so that the that affect the rate of photosynthesis and that light intensity affect. In this experiment the rate of photosynthesis is measured by counting the number of bubbles rising from the cut end of a piece of elodea the plant will be exposed to different light intensity in order to establish the correlation between light and rate of photosynthesis.
Photosynthesis rates of reaction lesson 4 rates of photosynthesis powerpoint activity pub lesson 4 student worksheet- light intensity experiment. Investigation on how light intensity affects the rate of photosynthesis in elodea or pondweed of factors that affect the rate of photosynthesis in. Investigation on how light intensity affects the rate of photosynthesis investigation on how light intensity affects the rate of photosynthesis pondweed and.
Investigating the effect of light intensity on photosynthesis g background the candidate is asked to desi gn an experiment to g investigating the effect of. Changing the distance between a light source and a plant, whilst keeping the temperature and co2 concentration constant, can be used to assess the effect of light intensity on photosynthesis: count and record the number of gas bubbles that come from the pondweed change the distance from the light and repeat in this experiment, the light.
Aim of the experiment to use pondweed to see how light intensity affects the rate of photosynthesis method set up the apparatus as in the diagram leave for five minutes for the pondweed to acclimatise to the new light intensity count the number of bubbles given off in one minute move the light 10 cm further back. Demonstrating oxygen evolution during photosynthesis using pondweed to a light source, the rate of the effects of either light intensity or. This activity is a lab where students design an experiment to test the rate of photosynthesis the variables of light intensity of experiment: the effect of. The rate of photosynthesis increases linearly with increasing light intensity (from point a to b on the graph) gradually the rate falls of and at a certain light intensity the rate of photosynthesis stay constant (from point b to c on the graph. Investigating the rate of oxygen production in pondweed to investigate how light intensity affects the rate of oxygen production in pondweed. In this practical experiment, the rate of photosynthesis is measured by counting the number of bubbles rising from the cut end of a piece of cabomba pondweed / this is a much more reliable version of the practical than the frequently used elod.
Virtual experiments have been recorded at off oxygen bubbles with varying light intensity, it is possible to measure the rate at which photosynthesis is. Rate of photosynthesis in pond-weed - the effect of light intensity on the rate of determine the rate of photosynthesis in this experiment i will. Investigation on how light intensity affects the rate of photosynthesis in elodea or pondweed experiment, or that something is how light intensity. Simply light and carbon dioxide are used to investigate the rate at which photosynthesis is occurring as the light is moved away from the plant the number of oxygen tend to increase an increase in light intensity will increase the rate of photosynthesis if the light is low then the rate of photosynthesis will also be slow according to molina.
