Correct option is C
(A) It has more than one chromosome: This is incorrect. Prokaryotic cells typically have one single, circular chromosome, located in the nucleoid region. They do not have multiple chromosomes like eukaryotic cells.
(B) Nuclear region is well defined and surrounded by nuclear membrane: This is incorrect. Prokaryotic cells lack a membrane-bound nucleus. The region where the DNA is concentrated is called the nucleoid, but it is not surrounded by a nuclear membrane.
(C) It has a single chromosome: This is correct. Most prokaryotic cells have one single, circular chromosome located in the nucleoid region, which is not enclosed by a membrane.
(D) Membrane-bound cell organelles are present: This is incorrect. Prokaryotic cells do not have membrane-bound organelles like the mitochondria, chloroplasts, or endoplasmic reticulum that are found in eukaryotic cells.
Information Booster:
Prokaryotic Cells: These are simpler cells, such as bacteria and archaea, which lack a true nucleus and membrane-bound organelles. They have a single, circular chromosome in the nucleoid and may also contain plasmids (small, circular DNA molecules).
Eukaryotic Cells: Eukaryotic cells have a membrane-bound nucleus and multiple linear chromosomes, along with various membrane-bound organelles such as mitochondria, Golgi apparatus, and the endoplasmic reticulum.
Additional Information:
Prokaryotic DNA: The single chromosome in prokaryotes is typically a circular DNA molecule that contains the genetic information for the cell's functions.
Lack of Organelles: Prokaryotic cells lack organelles such as nuclei, mitochondria, and chloroplasts found in eukaryotic cells.
