Study Notes
Categorization of Protists
- Animal-like protists are categorized based on their method of movement.
- Both animal-like and plant-like protists can exist as unicellular organisms.
Types of Protists
- Plant-Like Protists and Fungus-Like Protists are two main groups for classification.
- The discovery of DNA has led to significant changes in the classification of protists, with organisms being moved in and out of the kingdom Protista.
Disease Caused by Protists
- The parasite Plasmodium is responsible for causing malaria.
Classification Challenges
- The diverse characteristics among organisms make protist classification difficult.
Characteristics of Protists
- Unicellular animal-like protists are known as protozoans.
- Protist offspring can be genetically different from both parents, highlighting diversity in reproduction.
- Euglenoids and algae share the ability to be autotrophic, indicating a commonality among some protists.
Fundamental Traits of Protists
- All protists possess nuclei and predominantly inhabit moist environments.
