a simpler structure and are usually smaller in size compared to eukaryotic cells. Prokaryotic cells lack membrane-bound organelles, which are characteristic of eukaryotic cells. Instead, their genetic material is typically organized in a single circular chromosome and is located in a region called the nucleoid, rather than within a membrane-bound nucleus.
Moreover, prokaryotic cells often possess a cell wall, which provides structural support and protection, and they may have additional structures such as pili, flagella, and plasmids. Their reproduction occurs primarily through binary fission, a simpler process than the mitosis seen in eukaryotic cells. Overall, prokaryotic cells represent a more primitive cell type, adapted for diverse environments and often capable of rapid reproduction.
In summary, prokaryotic cells generally have:
- No well-defined nucleus
- No membrane-bound organelles
- A simpler structure
- Smaller size
- Circular DNA located in the nucleoid
- A cell wall (most species)
- Additional structures like flagella or pili
- Reproduction through binary fission
