How are algae different from protozoans?

Answer 1

Protozoa typically refer to heterotrophic, unicellular protists such as amoeba. The term algae is reserved for autotrophic protists. They can either be unicellular or multicellular aggregates.

Answer 2

First of all, protozoa is a crappy classification because it is the trash bag of the systematics world, and phylogeneticists are trying to phase out this group.

TECHNICALLY, in the old classification system, algae were protozoans. However, this is no longer the case because they were the only protists that photosynthesized. Algae are now a group of their own, and all of the other organisms are now classified as "animal like"

Answer 3

Both are protists. The algae contain chlorophyll and some contain other colorful pigments, and they are photosynthetic. The protozoans do not contain chlorophyll and are therefore heterotrophs.

Answer 4

Algae and protozoans are very alike. The one main difference between the two is the fact that algae do not move at all, and protozoans do.

Answer 5

Algae are able to make their own food, while protozoa ingest other organisms like animals. Algae are "autotrophs" while protozoa are "heterotrophs. "

Answer 6

So basically algae is a main food source, it is the grass for the underwater. Mainly they produce oxygen. They reproduce differently as well the reproduce sexualy.

Answer 7

Algae is more like plants because they don't move unless something moves them and protozoa is more like animals because they move around and eat other living organisms
