Question 8

Answer 1

The best reason why no bubbles were released during the first portion of the experiment is:

There was no light present for photosynthesis to occur.

Photosynthesis requires light energy to convert carbon dioxide and water into glucose and oxygen. In the absence of light, the process cannot take place, which is why no bubbles (indicative of oxygen production) were released.
