What are emergent hydrophytes?
Emergents. Emergent plants grow up from soil, too, and are often planted or found along the shoreline of a pond. Their roots are underwater, but their shoots grow up out of the water. These hydrophytic plants include cattails (Typha latifolia) and water lilies (Nymphaea odorata).
Do hydrophytes float on water?
The petioles have special modifications to suit the aquatic environment. Long, slender and delicate petioles are present in hydrophytes with their leaves floating on water surface ( Nymphaea). In some plants petiole is swollen to form a bulb like structure to help the plants to float on water (Eichhornia).

How does Lemna reproduce?
Lemna minor, or duckweed, is a small, free floating, aquatic plant capable of living in standing or slow moving water. Duckweed can reproduce sexually through seeding, although this type of reproduction is rare. The majority of the time Duckweed reproduces asexually through budding (How Does Duckweed Reproduce).
Is Spirodela polyrrhiza the same as duckweed?
Spirodela polyrhiza. Spirodela polyrhiza (orth. var. S. polyrrhiza) is a species of duckweed known by the common names common duckmeat, greater duckweed, great duckmeat, common duckweed, and duckmeat. It can be found nearly worldwide in many types of freshwater habitat.

Is Spirodela polyrhiza an efficient bio accumulator of mercuric chloride?
S. polyrhiza was found to be an efficient bio accumulator of mercuric chloride (HgCl 2) in labor settings. Its plant biomass showed a 1000 times higher mercuric chloride concentration than its aquatic environment. Spirodela polyrhiza showed the highest accumulation factor compared to Lemna gibba and Lemna minor, which were also investigated.
