Question

the following characters from the characterisitic features of phylum Protozoa, except……
most of them are unicellular
that it can’t be seen by naked eye
that it perform photosynthesis
its simple structure

Answer 1

The characteristic feature of Phylum Protozoa that does not match the others listed is that they perform photosynthesis. Protozoa are primarily unicellular, microscopic organisms that cannot be seen by the naked eye and have a relatively simple structure. While some protists may have symbiotic relationships with photosynthetic algae, Protozoa themselves are not known to perform photosynthesis. They are mainly heterotrophic, obtaining nutrients by ingesting organic matter.
