Microbiology Practice Test: Algae & Protozoa — Flashcards

Algae & Protozoa topics include: Biological and economic importance of algae, algae characteristics and classification, ecology and protozoa importance, protozoa characteristics, protozoa morphology and reproduction. 

Algae and protozoa are both microorganisms, but they have some key differences:

Algae are plant-like organisms that can be unicellular or multicellular. They can derive energy from photosynthesis and lack the true roots, stems, leaves, and specialized reproductive structures of plants. Algae are autotrophic organisms, meaning they can make their own food.

Protozoa are unicellular organisms with complex cell structures. They can be free-living or parasitic, and feed on organic matter like other microorganisms or organic debris. Protozoa can sometimes cause diseases, such as malaria, giardia, and toxoplasmosis. 

Protozoa are divided into four major groups:
Amoeboid protozoa or sarcodines
Flagellated protozoa or zooflagellates
Ciliated protozoa or ciliates
Sporozoans
