No light….no life!
This past fortnight has seen the Agricultural Science student immersed in an in-depth study of photosynthesis for the Department of Agriculture, Forestry and Fishery’s (DAFF) Plant Science Competition, “No light…no life! A focus on photosynthesis”. Over the coming weeks, the students will perform a series of experiments that show what a plant needs to live, how plants defy gravity in their search for light, how plants react to different light wavelengths and test carbon dioxide intake.
The students have made an exciting start by measuring the rate of photosynthesis via oxygen output using pondweed, Elodea. Their investigations so far have included photosynthetic rates both in the light and dark conditions, variations in photosynthetic rates due to different light intensities and a final test to prove the gas produce was in fact oxygen. A look at the Elodea under the microscope saw the amazing images of individual chloroplasts, the powerhouse where all the photosynthesis process happens!
Another aspect to the DAFF Plant Science Competition is the Art in Agriculture Awards where students get behind the lens and photograph photosynthesis in action! Their mission is to capture a great ‘landscape’ shot of a field crop basking in the sunlight! Dakotah Davis has already been snapping up every opportunity and will have a load of amazing images to choose from, including this beautiful photo of a field of peanuts she captured on her way back from Wondai.
It is set to be an amazing exploration into the world of plants and photosynthesis.
