1. Nucleus: Eukaryotic cells have a true nucleus that contains the cell's genetic material (DNA), while prokaryotic cells do not have a true nucleus. In prokaryotic cells, the DNA is located in a region called the nucleoid.
2. Organelles: Eukaryotic cells have membrane-bound organelles such as mitochondria, endoplasmic reticulum, and Golgi apparatus, which perform specific functions within the cell. Prokaryotic cells do not have membrane-bound organelles, although they may have some structures that perform similar functions.
3. Size: Eukaryotic cells are generally larger and more complex than prokaryotic cells.
4. Reproduction: Eukaryotic cells reproduce through mitosis, a process that involves the division of the nucleus and the cytoplasm. Prokaryotic cells reproduce through binary fission, a simpler form of cell division.
5. Cell wall: Both eukaryotic and prokaryotic cells may have a cell wall, but the composition of the cell wall is different. In prokaryotic cells, the cell wall is made of peptidoglycan, while in eukaryotic cells, the cell wall is made of cellulose or chitin.
6. Ribosomes: Eukaryotic cells have larger ribosomes (80S) compared to prokaryotic cells (70S).
7. Genetic material: Eukaryotic cells have linear DNA organized into multiple chromosomes, while prokaryotic cells have circular DNA organized into a single chromosome.
8. Complexity: Eukaryotic cells are generally more complex in structure and function compared to prokaryotic cells.

Eukaryotic Cells
- Nucleus: Present, surrounded by a nuclear membrane
- Membrane-bound organelles: Present, including:
- Endoplasmic reticulum (ER)
- Golgi apparatus
- Mitochondria
- Chloroplasts (in plant cells)
- Cytoskeleton: Present, consisting of microtubules, actin filaments, and intermediate filaments
- Ribosomes: Present, located in the cytoplasm and on the ER
- Cell size: Typically larger than prokaryotic cells (10-100 µm in diameter)
- Examples: Animal cells, plant cells, fungi, protists
Prokaryotic Cells
- Nucleus: Absent; genetic material organized into a nucleoid region
- Membrane-bound organelles: Absent
- Cytoskeleton: Absent
- Ribosomes: Present, located in the cytoplasm
- Cell size: Typically smaller than eukaryotic cells (1-10 µm in diameter)
- Examples: Bacteria, Archaea
Other Key Differences:
- DNA structure: Eukaryotic cells have linear chromosomes enclosed within the nucleus, while prokaryotic cells have circular chromosomes located in the nucleoid region.
- Cell division: Eukaryotic cells undergo mitosis and meiosis, while prokaryotic cells undergo binary fission.
- Complexity: Eukaryotic cells are more complex and have a higher level of organization than prokaryotic cells.
- Energy production: Eukaryotic cells produce energy in mitochondria, while prokaryotic cells produce energy in the cytoplasm.
- Motility: Prokaryotic cells often have flagella or pili for movement, while eukaryotic cells may have various types of motility structures, such as cilia or microtubule-based structures.
