Describe the term protozoa and algae, and indicate why the terms are outdated

What will be an ideal response?


Protozoa translates into “first animal”. Protozoa is a name for a diverse assemblage of heterotrophic
protists that were once considered to be animals. Algae refers to several groups of photosynthetic
protists. Therefore, neither term describes a taxonomic group of protists.
