What are plankton? - NOAA's National Ocean Service
An organism is considered plankton if it is carried by tides and currents, and cannot swim well enough to move against these forces. Some plankton drift this way for their entire life cycle. Others are only classified as plankton when they are young, but they eventually grow large enough to swim against the currents.

2011年4月18日 · There are two main kinds of plankton: phytoplankton, which are also called algae, and zooplankton. A rotifer (a type of zooplankton) swims through a group of phytoplankton cells in this microscope image. Phytoplankton are like plants.
