CO2

Answer 1

The gas bubbles produced in the investigation are most likely to contain molecules of **oxygen**.

When aquatic plants undergo photosynthesis, they take in carbon dioxide and water and, in the presence of light, produce glucose and release oxygen as a byproduct. Therefore, if the plant is exposed to a light source, the gas bubbles observed would primarily be oxygen.
