उत्तर
Buoyancy in Eichhornia results from spongy enlargements of the petioles.
Explanation:
These swollen and spongy petioles contain large air chambers that provide buoyancy, allowing Eichhornia to float freely on water surfaces. This structural adaptation helps the plant to remain afloat and access sunlight for photosynthesis effectively in its aquatic habitat. Such specialized morphological features are essential for hydrophytes like Eichhornia to live and thrive in water environments.
