There was no light present for photosynthesis to occur

There was no carbon dioxide present for photosynthesis to occur
There was no carbon dioxide present for photosynthesis to occur

There was no oxygen present for photosynthesis to occur

Answer 1

The best reason why no bubbles were released during the 5 minutes when the lights were turned off is:

There was no light present for photosynthesis to occur.

Photosynthesis requires light energy to convert carbon dioxide and water into glucose and oxygen, which are released as bubbles in the process. Without light, the photosynthetic process cannot take place, resulting in no bubble production.
