Photosynthesis results in buoyancy due to the accumulation of $O_2$ bubbles.

Vedclass · Answer

(C) During the day,submerged plants perform photosynthesis. As a result of photosynthesis,$O_2$ is produced as a byproduct. These $O_2$ bubbles get trapped in the plant body or on the surface of the leaves,which increases the buoyancy of the plant,causing it to float on the water surface. At night,photosynthesis stops,and the $O_2$ bubbles are either consumed in respiration or escape into the water,causing the plant to lose its buoyancy and sink to the bottom.
