Question

25 - 26 biology a / module 4. classification

1. what characteristic do all protozoa display?

immobile
vertebrate
autotrophic
eukaryotic

Explanation:

Protozoa are single - celled organisms. They are not immobile as many protozoa can move (e.g., amoebas with pseudopodia, paramecia with cilia). They are not vertebrates as vertebrates are multi - celled animals with a backbone. They are not autotrophic (which means they cannot produce their own food like plants do through photosynthesis). Protozoa are eukaryotic, meaning their cells have a nucleus and other membrane - bound organelles.

Answer:

eukaryotic
