Where does bubbles of plants came from?

Bubbles in plants, often seen in aquatic species, originate from the release of gases during photosynthesis. When plants absorb carbon dioxide and water, they convert these into glucose and oxygen, with oxygen being released as a byproduct. Under certain conditions, this oxygen can accumulate and form visible bubbles, particularly in water environments. Additionally, bubbles can also form from trapped air in the plant tissues or during the process of transpiration.
