Plankton. Plankton includes plants and animals that float along at the mercy of the sea's tides and currents. Their name comes from the Greek meaning drifter or wanderer.. There are two types of plankton: tiny plants--called phytoplankton, and weak-swimming animals--called zooplankton.Some are babies that will grow into strong-swimming, non-planktonic adults. Others will remain plankton for their entire lives.here are two types of plankton: tiny plants--called phytoplankton, and weak-swimming animals--called zooplankton.

There are many types of phytoplankton, but two main are most common: 1) diatoms and 2) dinoflagellates. Diatoms are single-celled algae that have chloroplasts and can undergo photosynthesis.Dinoflagellates are also single-celled and have two whip-like tails called âflagella.â Although many dinoflagellates also have chloroplasts, not all do.oth types of phytoplankton can be autotrophic and use photosynthesis to harvest the sunlight to produce their own energy, but some dinoflagellates are heterotrophic and rely on eating other organisms for energy; as far as we know, there are no heterotrophic diatoms.
