Question

Поставьте сосуд с водным растением элодеей под яркий свет осветительной лампы. Вскоре вы увидите в воде появляются пузырьки воздуха. Почему?

Answer 1

На ярком свету у элодеи ускоряется  процесс фотосинтеза, в результате которого растение выделяет кислород, именно его пузырьки и выделяются в воду.

Answer 2

Explanation of the Observation

When you place a vessel containing the water plant Elodea under a bright light source, you will observe the appearance of bubbles in the water. This phenomenon occurs due to the process of photosynthesis carried out by the Elodea plant.

Role of Photosynthesis

Photosynthesis is the process by which green plants, algae, and some bacteria convert light energy into chemical energy in the form of glucose, using carbon dioxide and water. This process releases oxygen as a byproduct.

Photosynthesis in Elodea

The bubbles observed in the water when the Elodea plant is exposed to bright light are actually oxygen bubbles produced during the process of photosynthesis. The plant takes in carbon dioxide from the water and releases oxygen as a result of the light-dependent reactions of photosynthesis.

Conclusion

In summary, the appearance of bubbles in the water when a vessel containing Elodea is placed under a bright light source is due to the process of photosynthesis carried out by the plant, where oxygen is released as a byproduct.
