Amoebozoa

Amoebozoa is a major eukaryotic group that includes amoebas, slime molds, and related organisms. Many members move or feed using broad, flowing pseudopodia.

Eukaryote: An organism whose cells contain a nucleus and other membrane-bound compartments. Amoebozoa belongs to the eukaryotes, whose cellular organization frames its classification.
Amoeboid movement: Cell movement produced by changing shape and extending temporary protrusions. It describes how many amoebozoans crawl across surfaces or through wet environments.
Amoeba proteus: A large freshwater amoeba known for its changing shape and broad pseudopodia. It is a familiar example of a free-living amoebozoan that feeds by engulfing prey.
Thomas Cavalier-Smith: A British evolutionary biologist known for influential proposals about eukaryotic classification. His taxonomic work helped establish Amoebozoa as a major eukaryotic group.
Pseudopodium: A temporary cell protrusion used for movement, attachment, or engulfing material. Broad pseudopodia are a characteristic means of movement and feeding in many amoebozoans.
Cytoplasmic streaming: The directed movement of cytoplasm within a cell. Flowing cytoplasm helps extend pseudopodia in large amoeboid cells.
Dictyostelium discoideum: A soil-dwelling social amoeba that can aggregate into a multicellular fruiting structure. Its life cycle links solitary amoeboid feeding with coordinated group behavior.
Molecular phylogenetics: The reconstruction of evolutionary relationships using molecular sequence data. Sequence comparisons reshaped the placement and internal classification of amoebozoans.
Phagocytosis: A cellular process in which a cell engulfs particles into membrane-bound compartments. Many amoebozoans obtain food by engulfing bacteria and other small particles.
Encystment: The formation of a resistant dormant cyst that helps an organism survive unfavorable conditions. Some amoebozoans form cysts when food, moisture, or other conditions become unfavorable.
