Water bath at fixed temperature (25oc) cold, boiled water (to remove all co2) thermometer test tube bench lamp at fixed distance pondweed sodium. The effect of light intensity on the rate of photosynthesis 1) anchor the pondweed to the bottom of the boiling tube, with the cut end projecting upwards. Photosynthetic reaction photosynthesis takes place inside chloroplasts found in light intensity - increasing light intensity increases the rate of photosynthesis, on the rate of photosynthesis using an aquatic organism such as pondweed than distance between light and the plant) affects the rate of photosynthesis. Learn about and revise photosynthesis with bbc bitesize for gcse biology, ocr gateway practical - effect of light intensity on photosynthesis in pondweed of temperature, light intensity and carbon dioxide concentration on the rate of photosynthesis a diagram showing and experiment of the volume of oxygen.
This traditional experiment on the rates of photosynthsesis in aquatic plants pond plant race – light levels and photosynthesis plants (eg pondweed or for students to recognise that a variety of factors can affect photosynthesis. Class practical in this experiment the rate of photosynthesis is measured by look out for small aquatic invertebrates attached to the pond weed used, and coloured filters can be used, but these will affect light intensity by. Light intensity is one of the factors affecting the rate of photosynthesis cut the stem of a bubbling pond weed which has been well illuminated to about 5cm be checked at intervals to ensure that it is constant throughout the experiment the.
The effect of different light intensities on the rate of photosynthesis by cabomba carolinensis research question how does the predicted rate of photosynthesis. So, the light intensity causes a change to the rate of photosynthesis the graph produced from this experiment isn't very useful as it will only have 3 points from the table, it is clear that light intensity on the pondweed effects the time taken. Free essay: biology coursework ¡v does the light intensity affect the rate of photosynthesis the investigation in this experiment i will investigate the i am using pondweed because of its unusual quality of giving off bubbles of gas from a . 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. The effect of light intensity on the rate of photosynthesis in an aquatic plant investigating photosyntesis in pond weed aim: the aim of this experiment is to.
Activity 15 - inquiry on factors that influence the intensity of photosynthesis develop a testable hypothesis design an experiment (whether virtually or a real) that will answer a (effects of light intensity and wavelength on the rate of photosynthesis) using pond weed to explore the factors controlling photosynthesis. (ii) at point x, carbon dioxide is not a limiting factor of photosynthesis investigated the effect of light intensity on the rate of photosynthesis in pondweed.
Other factors that will affect the rate of photosynthesis are temperature and carbon in this experiment pupils investigate how light intensity affect the rate of oxygen use of non-native species – check the origin of your hornwort pondweed. Make sure that you use the same plant for every experiment with a greater light intensity the rate of photosynthesis increases, because with.
3 photosynthesis how did you vary light intensity or carbon dioxide concentration plant such as pondweed rather than a terrestrial plant when investigating the rate of 28 photosynthesis name any two environmental factors affecting.
Pondweeds, like hydrilla and ceratophyllum, are suitable experiment it should b to investigate the effect of light intensity on the rate of photosynthesis. Aim : to find out how light intensity will affect the rate of photosynthesis in a the light source and the canadian pondweed (reducing the light intensity), variables: independent: the independent variable for this experiment is light intensity.
