A green pondweed growing in water produces a lot of bubbles when it is kept under a bright light. When the light is switched off the plant stops producing bubbles.
|
1. In the space opposite draw a diagram of the apparatus that you would use to collect the gas bubbles so that they can be tested. (If
you are answering this question in a word processing programme, use a draw programme and import your file.) |

2. The gas produced by the plant is, in fact, oxygen. How could you prove that it is oxygen? |
