Study Notes
Cellular Organization and Differentiation
- All living things are composed of cells
- Cells in multicellular organisms have different functions
- Cells work together for survival and life
Unicellular Organisms
- The smallest unit of life
- Perform all life functions within a single cell
- Examples include: absorbing nutrients, reacting to the environment, disposing of waste, growing, and reproducing
- Prokaryotes: lack membrane-bound organelles (e.g., bacteria)
- Eukaryotes: have membrane-bound organelles (e.g., amoeba, Paramecium)
- Unicellular organisms may exist in colonies or individually
Multicellular Organisms
- Composed of many cells
- Cells have specialized roles and work together
- Differentiation: cells develop into different types to perform specific tasks
- Each cell type has a specific job crucial for the organism's survival
Cell Differentiation
- All organisms begin as a single cell
- Mitosis (cell division) occurs rapidly following the initial stage
