Good experimental technique
Leaf cells contain small organelles called chloroplasts. Chloroplasts contain chlorophyll and are the sites within the leaf cells where photosynthesis takes place. White light is made up of many different colours. It is important for us to know what colour or colours plants need in order to photosynthesise.
Design an experiment to answer the following questions.
Do green plants need green light to photosynthsize?
What colour (or wavelength of light) do plants need in order to photosynthesise?
Points to consider when setting up your experiment.
Obtain several small plants that grow quickly and pieces of different coloured cellophane. Set up your experiment.
Write up your experiment under the following categories.
Heading - Title of the experiment.
