Hint: Prokaryotic cells comprise bacteria and Archaea. Their genetic material isn't stored within a membrane-bound nucleus. Instead, it is stored in a nucleoid that floats in the cell's cytoplasm.
Complete Answer:
- Prokaryotic cells are normally smaller than eukaryotic cells, with a typical size range of 0.1 to 5 micrometers in diameter.
- Prokaryotic cells are primitive as they lack membrane-bound cell organelles. The genetic material of a prokaryotic cell is a single chromosome made up of a single strand of DNA.
- Prokaryotes have a cell membrane or plasma membrane that acts like a protective cover. They also have a rigid cell wall for added support and protection.
- Prokaryotic cells have ribosomes, which are molecules that make proteins.
- Prokaryotic cells do not have a nucleus but instead have a piece of circular, double-stranded DNA located in an area of the cell called the nucleoid.
Thus, the correct option is: C) Both A and B.
Note: Characteristics of prokaryotic cells:
- They do not have a nucleus.
- Their cell wall is made up of amino acids and carbohydrates.
- They can divide asexually by binary fission and sexually by conjugation.
- Mitochondria, chloroplasts, Golgi bodies, and lysosomes are not present.
- Plasma membrane is present and it also functions as a mitochondrial membrane.
