Conceptual Vocabulary
ProtistProtists are a diverse group of organisms, comprising those eukaryotes that cannot be classified in any of the other kingdoms as fungi, animals, or plants.
PseudopodPseudopods are temporary projections of eukaryotic cells possessed by cells generally referred to as amoeboids.
AmoebozoaThe Amoebozoa are a major group of amoeboid protozoa, including the majority that move by means of internal cytoplasmic flow.
ProtozoaProtozoa are one-celled eukaryotes that commonly show characteristics usually associated with animals, such as mobility and heterotrophy.
VacuoleVacuoles are membrane-bound compartments within some eukaryotic cells that can serve a variety of secretory, excretory, and storage functions.
FlagellateFlagellates are cells with one or more whip-like organelles called flagella.
AmoeboidAmoeboids are cells that move or feed by means of temporary projections, called pseudopods.
EuglenidThe euglenids are one of the best-known groups of flagellates, commonly found in freshwater especially when it is rich in organic materials. Many have chloroplasts and produce energy through photosynthesis.
DiatomDiatoms are one of the most common types of phytoplankton, having cells encased within a unique cell wall made of silica called a frustule.
DinoflagellaThe dinoflagella are a large group of flagellate protists about half of which are photosynthetic, making up the largest group of eukaryotic algae aside from the diatoms.
ExtrusomeExtrusomes are membrane-bound structures in some eukaryotes which, under certain conditions, discharge their contents outside the cell.
HeterokontThe heterokonts or stramenopiles are a major line of eukaryotes most of which are algae, ranging from the giant multicellular kelp to the unicellular diatoms.
Sleeping sicknessSleeping sickness or African trypanosomiasis is a parasitic disease in people and animals, caused by protozoa of genus Trypanosoma and transmitted by the tsetse fly.
OomyceteOomycete, or water molds, are a group of filamentous, unicellular protists, physically resembling fungi.
CiliateThe ciliates are one of the most important groups of protists. Cilia are possessed by all members of this group.
EuglenozoaThe Euglenozoa are a large group of flagellate protozoa including a variety of common free-living species, as well as a few important parasites. There are two main subgroups, the euglenids and kinetoplastids.
MetamonadThe metamonads are a large group of flagellate protozoa. Their composition is not entirely settled, but they include the retortamonads, diplomonads, and possibly the parabasalids and oxymonads as well.
CytostomeA cytostome or cell mouth is a part of a cell specialized for phagocytosis, usually in the form of a microtubule-supported funnel or groove.
PhytoplanktonPhytoplankton are the autotrophic component of plankton.
PellicleThe pellicle is a thin layer supporting the cell membrane in various protozoa.
PercolozoaThe Percolozoa are a group of colourless protozoa, including many that can transform between amoeboid, flagellate, and encysted stages.
MicronucleusA micronucleus is the smaller nucleus in ciliate protozoans.
MacronucleusA macronucleus is the larger type of nucleus in ciliates.
