Prokaryotic Cells: What Makes Them Unique?
What are some key characteristics of prokaryotic cells?
Choose the answer below:
- Prokaryotic cells have a cell wall, ribosomes, and a nucleoid region with DNA. Some may also have a protective capsule, flagella, pili and plasmids.
- Prokaryotic cells have a nucleus, mitochondria, and endoplasmic reticulum.
- Prokaryotic cells are larger in size compared to eukaryotic cells.
Answer:
Prokaryotic cells have a cell wall, ribosomes, and a nucleoid region with DNA. Some may also have a protective capsule, flagella, pili and plasmids.
Prokaryotic cells are simple, yet fascinating organisms that have unique characteristics setting them apart from eukaryotic cells. One of the key features of prokaryotic cells is their cell wall. This structure provides protection and maintains the shape of the cell.
In addition to the cell wall, prokaryotic cells contain ribosomes, which are responsible for protein synthesis. The nucleoid region within the cell houses the genetic material in the form of DNA. Most prokaryotic cells have a single circular chromosome located in this region.
Some prokaryotic cells may possess additional features such as a protective capsule, which helps in resisting harsh environmental conditions. Flagella are used for movement, while pili assist in attaching the cell to surfaces. Prokaryotic cells may also contain plasmids, which are extra-chromosomal DNA that can carry additional genetic information.
These characteristics collectively make prokaryotic cells unique and adaptable to diverse environments. By understanding these features, we can appreciate the diversity and complexity of the microbial world.
