Final answer:
Ciliates are a group of alveolates that use tufts of short flagella-like structures called cilia to move themselves or move water past their cell surfaces. They have a large macronucleus and a smaller micronucleus. Notable examples include Vorticella, Balantidium coli, Didinium, and Paramecium.
Step-by-step explanation:
Ciliates are a group of alveolates that have numerous short flagella-like structures called cilia. They can either move themselves or move water past their cell surfaces using these tufts of cilia. Ciliates have two nuclei: a large macronucleus and a smaller micronucleus. Notable examples of ciliates include Vorticella, Balantidium coli, Didinium, and Paramecium.
