Study Notes
Protist Characteristics
- All protists are eukaryotes, meaning their cells contain membrane-bound organelles, including a nucleus.
- Protists are a diverse group, not easily categorized into a single evolutionary lineage (polyphyletic).
- Some protists exhibit characteristics similar to plants (e.g., algae), fungi (e.g., slime molds), or animals (e.g., protozoans).
- Some protists are heterotrophic (consuming others) and others are photosynthetic or a combination of both.
Eukaryotic Cells
- Unlike prokaryotic cells (like bacteria), eukaryotic cells possess membrane-bound organelles.
- The nucleus is a defining feature, separating its contents from the cytoplasm.
Kingdom Protista
- Protists are single-celled organisms.
- They are classified into the Kingdom Protista because they cannot be categorized as plants, animals, or fungi despite sharing some traits with these kingdoms.
Protist Characteristics
- All protists are eukaryotes, meaning their cells contain membrane-bound organelles, including a nucleus.
- Protists are a polyphyletic group, meaning they don't share all the same qualities and some overlap with other kingdoms (plants, animals, fungi).
- Some protists exhibit plant-like (algae), fungus-like (slime molds), or animal-like (protozoans) characteristics.
- Some protists are heterotrophic, combining animal-like hunting with photosynthesis.
Eukaryotic Cells
- Eukaryotic cells, unlike prokaryotic cells (e.g., bacteria), have membrane-bound organelles within their cell membrane or wall.
- These organelles, such as the nucleus, are separated from the cytoplasm by a membrane.
Protist Classification
- The kingdom Protista includes single-celled microorganisms that don't fit into the plant, animal, or fungi kingdoms.
- The classification of protists is complex due to their diverse characteristics and overlapping traits with other kingdoms.
