b) Place a green plant/ weed in an inverted funnel.


c) Place an inverted test tube on the funnel as shown in the Fig 6.


d) As the process of photosynthesis begins, oxygen bubbles can be seen in the water of the funnel and test tube. The presence of these bubbles is an indicator of process of photosynthesis. As we know that oxygen is a by-product of photosynthesis.
