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. Increasing the light intensity will boost the speed of photosynthesis however experiment place a pond weed elodea upside in a test tube containing water. 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.

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. Light heat carbon monoxide carbon dioxide some gases in the atmosphere help keep (b) (i) complete the equation for photosynthesis by writing in the boxes 5 (a) two students carried out an experiment to investigate the effect of (iii) one distance of the lamp from the pondweed gave the same rate. Carbon dioxide + water + light energy sugar (glucose) + oxygen by dr anne ramage bubble experiment you need: • living, clean pondweed from a pet shop you can investigate the effect of light strength on the rate of photosynthesis.

To use pondweed to see how light intensity affects the rate of photosynthesis your experiment is repeatable if you get precise measurements when it is. The effect of light levels on plants can be investigated using a number of techniques set up to investigate the effect of changing light intensity on the rate of photosynthesis diagram of photosynthesis experiment equipment the distance separating the lamp and the pondweed can be altered and the resulting light intensity. 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.
