Classified in the frog's-bit family ( Hydrocharitaceae ), Elodea is native to the Americas [ 1 ] and is also widely used as aquarium vegetation and laboratory demonstrations of cellular activities.
Elodea bifoliata, commonly called twoleaf waterweed, is a species of perennial flowering plant in the waterweed genus, Elodea. It grows in much of the western United States and Canada. It was only recognized as a separate species in the 1960s. It is found growing in streams and shallow bodies of water.
Elodea densa flower. Elodea densa is an aquatic plant growing in water up to 4 m (13 ft) deep, with trailing stems to 2 m (6.6 ft) or more long, producing roots at intervals along the stem. The leaves are produced in whorls of four to eight, 1–4 cm (0.39–1.57 in) long and 2–5 mm (0.079–0.197 in) broad, with a pointed leaf tip.

[ 3 ] [ 4 ] [ 5 ] It has been introduced widely to regions outside its native range and was first recorded from the British Isles in about 1836.
The frame rate is thus limited to the repetition rate of the laser system or the frame rate of the CCD camera. Lower damage in cells. In aqueous systems (such as cells), medium to low repetition rates (1 – 200 kHz) allow for thermal diffusion to occur between illuminating pulses so that the damage threshold is higher than with high repetition ...
Elodea nuttallii is a species of waterweed known by the common name western waterweed or Nuttall's waterweed. [3] This is a perennial aquatic plant which is native to North America where it grows submersed in lakes, rivers, and other shallow water bodies.
