Study Notes
Major Categories of Cells
- Two main categories: Prokaryotic and Eukaryotic.
- Prokaryotic cells lack a nucleus and are exemplified by bacteria.
- Eukaryotic cells have a true nucleus and include plants and animals.
Properties and Structure of Prokaryotes
- Prokaryotes are the most ancient and simplest form of life, considered the first cells on Earth.
- Do not possess an organized nucleus; DNA is dispersed in the cell's interior.
- Lack significant membrane-bound organelles, with only the cell membrane and ribosomes present.
Common Shapes of Prokaryotes
- Bacillus: rod-shaped structure.
- Coccus: spherical structure.
- Spirilla: spiral or corkscrew shape.
Eukaryotic Cell Structure
- Eukaryotic cells have DNA organized into chromosomes contained within a nucleus.
- Possess membrane-bound organelles, enhancing cellular functions.
- Most complex cells fall under this category.
Differences Between Prokaryotic and Eukaryotic Cells
- The primary distinction is the presence of a nucleus; eukaryotic cells have one, while prokaryotic cells do not.
- Eukaryotic cells feature various membrane-bound organelles such as mitochondria and Golgi apparatus, which prokaryotes lack.
Commonalities Between Prokaryotic and Eukaryotic Cells
- Both cell types share essential components: DNA, cell membrane, and ribosomes.
