Study Notes
Amoeba Movement and Habitat
- Primary mode of movement is through pseudopodia, which involves the cytoplasm pushing the plasma membrane to create projections.
- Amoebas inhabit various environments, typically found in freshwater, saltwater, and damp soil.
Historical Context
- Detailed illustrations of an amoeba specimen were created by the scientist Maria Sibylla Merian in 1755.
- The first historical references to amoebas date back to the 19th century.
Structure and Composition
- The primary components of an amoeba's structure are the cytoplasm, plasma membrane, and nucleus.
- Amoebas are classified as unicellular organisms capable of changing their shape.
Health Implications
- Some amoebas can invade the human body, potentially leading to various diseases and infections.
