As protozoa are rather large on the micro scale, one does not need oil immersion lenses or high power. analogy- one does not need extreme lens speed or shutter speeds to photograph large stationary objects such as Bridges or buildings! moving targets are another matter.

What characteristics do the protozoa share?

The word "protozoon" is a catch-all for any single-celled eukaryote. That's all they have in common; they've got a nucleus. "Protozoa" is an archaic taxon, and over the years has since been split into various other kingdoms including Amoebozoa, Excavata, Rhizaria, and more.

Does protozoa have flagella?

Yes

A flagellum, also called undulipodium, is a whip-like structure used for locomotion, for feeding or other purposes. Almost all organisms have flagella to include protozoa (at some stage in their lives). We humans have them in our bodies. Even our own spermatozoa can be regarded as flagellates. All these flagella have a similar basic design. flagellum, also called undulipodium, is a whip-like structure used

What is the difference in paramecium euglena and amoeba?

Euglena, Paramecium and Amoeba are all monocellular organisms. The major difference lies in their mode locomotion. The amoeba moves with the help of its pseudopodia, that are temporary protrusions of cytoplasm, giving leg like appearance. In paramecium, there are small outgrowths that are called as Cilia (Sing. Cilium). These cilia are thousands in number and are present all over the cells' surface. They act like an oar. Finally, Euglena have Flagellum (plur. flagella). A flagella beats like a whip to provide driving force for the movement.

Apart from this, both Euglena and Paramecium have a fixed body shape but amoeba continuously keeps on changing its shape . Amoeba and Paramecium are heterotrophic and lack chloroplast while Eugena has chloroplasts and could synthesise its own food. Amoeba and Euglena are monokaryotic ( One nucleus only) while paramecium has two nuclei and is dikaryotic.
