<span>Jane's observation will be that in the transparent bottle, the algae and small plants present in the pond water release oxygen during photosynthesis, while in the dark bottle, photosynthesis doesn’t occur due to darkness. Therefore, oxygen in the transparent bottle is more than that in the dark bottle. In photosynthesis, photosynthesizing organisms, such are algae and small plants, use carbon dioxide and water and convert it into glucose and oxygen in the present of sunlight. Therefore, organisms in the transparent bottle can perform photosynthesis and consequently release oxygen. However, this is not the case with the dark bottle that cannot transmit the sunlight.</span>
