Study Notes
Prokaryotic vs. Eukaryotic Cells
- Prokaryotic cells are characterized by their lack of a membrane-bound nucleus and other membrane-bound organelles.
- Eukaryotic cells, in contrast, contain a nucleus and other organelles enclosed by membranes.
- Bacteria are classified as prokaryotes.
Key Characteristics of Prokaryotes
- Lack a nucleus. This means their genetic material (DNA) is not contained within a membrane-bound compartment.
- Do not possess membrane-bound organelles like mitochondria, endoplasmic reticulum, or Golgi apparatus, which are common in eukaryotic cells.
- Their DNA is typically a single, circular chromosome located in a region of the cytoplasm called the nucleoid.
- Possess a cell wall composed of peptidoglycan (in most bacteria).
- Often smaller in size than eukaryotic cells.
- Can have a wide range of shapes, from cocci (spherical), bacilli (rod-shaped), to spirilla (spiral).
