In the questions below organism refers to genus, e.g. Paramecium, Plasmodium; group refers to major taxonomic categories equivalent to phyla in animal taxonomy (e.g. Diatoms, Ciliates, Apicomplexa, Cryptomonad). Subgroup refers to divisions within these, e.g., hypotrich ciliate, centric diatom, coccidian apicomplexan.


Where alternative terms are indicated in brackets, please underline or circle the proper alternative.
