Study Notes
Cell Structure and Specialization
- Amoebas are single-celled organisms, whereas humans are multicellular organisms.
- The main advantage of cell specialization in humans is that it allows for the division of labor, enabling different cells to perform specific functions efficiently.
- Amoebas do not need a complex body structure because they are able to perform all necessary functions, such as movement, digestion, and respiration, within a single cell.
- In humans, the hierarchy of increasingly complex structures is: cells → tissues → organs → organ systems.
- A characteristic not exhibited by amoebas is a fixed body shape, as they are able to change their shape to adapt to their environment.
