Floating leaf disks for observing and investigating photosynthesis

This online resource provides a way of demonstrating photosynthesis in action.

The procedure used for this investigation was produced by the ARC Centre of Excellence for Translational Photosynthesis.

It is well illustrated and uses leaf disks suspended in water to demonstrate the production of oxygen during photosynthesis.

Oxygen producing plants

Oxygen producing plants: Can we use Ceratophyllum demersum (fox tail—a hornwort) as an alternative plant to Hydrilla verticillata in WA? I have tested this plant for the experiment and it is much more effective at producing oxygen, but is similar to the Hydrilla plant in many ways. It is again an aquatic weed and a declared weed in Tasmania but permitted in WA according to the department of Agriculture and Food WA.
