Examples from the kingdom Protista include paramecium, amoebas and plasmodium vivax. These protists are considered more animal-like. Protists that are plant-like include dinoflagellates, euglena, chlamydomonas and ulva. Kelp, laminaria and volvox are also plant-like protists.
The paramecium belongs to a division of Protista known as Ciliophora. It lives in fresh water and moves around by way of cilia. The paramecium is a somewhat more complex organism than some other protista because it has a large macronucleus, a number of smaller micronuclei and reproduces sexually.
Plasmodium belongs to a division called Apicomplexa. All of the protists in this division are parasitic and reproduce by way of spores. Plasmodium is notorious because it is the protist that causes malaria.
The amoeba is a one-cell protist that lives in fresh water. It is a member of the Rhizopoda division. It moves around by a pseudopod, or a false foot, and lacks the paramecium's cilia. Some types of amoebas cause amoebic dysentery if they are ingested.
Dinoflagellates can be found in the ocean among plankton. They are bioluminescent and toxic to humans. Sometimes they grow so numerous that they turn the water red, leading to a phenomenon called red tide.
Chlamydomonas belong to the Chlorophyta division. They contain chloroplasts and chlorophyll, and some scientists believe they are the ancestors of green plants.
