Study Notes
Laboratory Exercise 3
- Focuses on the morphology and diversity of protists
Habitat of Protists
- Most protists live in aquatic environments, such as freshwater and marine ecosystems, as well as in moist soil and decaying organic matter
Characteristics of Protozoans
- Are eukaryotic, single-celled organisms
- Typically microscopic in size
- Have the ability to move using structures such as cilia, flagella, or pseudopodia
- Are heterotrophic, obtaining nutrients by ingesting other organisms or organic matter
Classification of Animal-Like Protists
- Classified based on their morphology and movement characteristics
- Examples include sarcodines (amoebas), flagellates (Giardia), and ciliates (Paramecium)
Classification of Protists
- Determined by their morphology, physiology, and genetic characteristics
- Can also be classified based on their nutritional modes, such as autotrophic (producing their own food) or heterotrophic (obtaining nutrients from other sources)
