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.
Questions 1-5 will carry twice the weight of other
questions.
