Study Notes
Lesson Objective
- Distinguish features and functions of prokaryotic and eukaryotic cells.
Differences Between Prokaryotic and Eukaryotic Cells
-
Prokaryotic Cells:
- Found in organisms classified as prokaryotes, including bacteria and archaea.
- Typically unicellular, consisting of a single cell.
- Lack membrane-bound organelles such as mitochondria, lysosomes, and Golgi apparatus.
- DNA is located in the nucleoid region, consisting of a single strand in bacterial cells.
- May possess a capsule for extra protection and structures like pili for attachment and flagella for movement.
-
Eukaryotic Cells:
- Characteristic of complex organisms, including animals, plants, fungi, and protists (like algae and amoeba).
- Can be multicellular (comprising multiple cells) or unicellular (e.g., amoeba).
- Contain membrane-bound organelles, including nuclei, endoplasmic reticulum, Golgi apparatus, and more.
- DNA is contained within a defined nucleus.
- Exhibit various structures for movement, such as flagella (ex: sperm) and cilia (for attachment).
