The best reason why no bubbles were released during the first 5 minutes of the experiment is: There was no light present for photosynthesis to occur.
Photosynthesis requires light to drive the reactions that produce oxygen and other byproducts, so without light, the process cannot occur, resulting in no gas bubbles being released.
