Introduction to Protozoans

The video tutorial explains the movement and characteristics of different protozoans, including ciliates, flagellates, and sarcadines. Ciliates, like paramecium, use cilia for movement and have nuclei and food vacuoles. Flagellates move with a whip-like flagellum. Sarcadines, such as amoebas, use pseudopods for movement and feeding. Amoebas lack a definite shape, have a nucleus, and reproduce by cell division.

Explain the movement mechanism of flagellates.

What is a pseudopod and how does it function in amoebas?
