Question

You do a demonstration of photosynthesis for your friends with the aquatic plant Elodea outside on a sunny day. You put the plant in baking soda (a source of carbon dioxide) and water. After some time your friends notice bubbles emerging from the plant and ask you what they bubbles are. You tell them it is:________________

Answer 1

Hydrogen gas/bubbles

Step-by-step explanation:

Photosynthesis is defined as the process by which green plants and other organisms like blue-green algae etc. synthesize organic matter. In the presence of light energy, they convert CO2 and H2O into organic sugar with the release of O2 gas.

The plant was performing photosynthesis since there is the presence of CO2 (baking soda) and water and therefore the bubbles seen is hydrogen gas guven off from photosynthesis .

6CO2(g) + 6H2O(l) --> C6H12O6(s) + 6O2(g)
