What are Phytoplankton? - NASA
Derived from the Greek words phyto (plant) and plankton (made to wander or drift), phytoplankton are microscopic organisms that live in watery environments, both salty and fresh.. Some phytoplankton are bacteria, some are protists, and most are single-celled plants. Among the common kinds are cyanobacteria, silica-encased diatoms, dinoflagellates, green algae, and chalk-coated coccolithophores.

Duckweed Control - Easily Kill Duckweed in Your Pond
Duckweed is one of the smallest flowering, free-floating plants found around the world. Measuring just 1/16" to 1/4" in length, duckweed floats on the water surface in colonies not attached to the bottom. Duckweed floats wherever the wind or currents take it, absorbing nutrients from the leaf undersurface and a very fine root hanging from it.
