Verified Answer
Choose the correctly matched pair.a)Prokaryotic Cell - Membrane-bound ...
- Option A: Prokaryotic Cell - Membrane-bound cell organelles present
Incorrect. Prokaryotic cells do not have membrane-bound cell organelles. They lack structures such as mitochondria, Golgi apparatus, and endoplasmic reticulum, which are found in eukaryotic cells.
- Option B: Eukaryotic Cell - Single chromosome
Incorrect. Eukaryotic cells have multiple chromosomes contained within a well-defined nucleus, unlike prokaryotic cells which typically have a single, circular chromosome.
- Option C: Prokaryotic Cell - Nuclear region not well defined
Correct. Prokaryotic cells have a nuclear region that is not well defined and is known as the nucleoid. This region is not enclosed by a nuclear membrane.
- Option D: Eukaryotic Cell - Nuclear region not well defined
Incorrect. Eukaryotic cells have a well-defined nuclear region that is surrounded by a nuclear membrane, distinguishing them from prokaryotic cells.
The correct answer, therefore, is Option C: Prokaryotic Cell - Nuclear region not well defined.

Understanding Prokaryotic and Eukaryotic Cells
Prokaryotic and eukaryotic cells represent two fundamental types of cellular organization in biology. Let's break down the key features that differentiate them.
Prokaryotic Cells
- Nuclear Region: In prokaryotic cells, the nuclear region is not well defined. This means that the genetic material, usually a single circular chromosome, is located in an area called the nucleoid, which is not surrounded by a membrane.
- Membrane-bound Organelles: Prokaryotic cells lack membrane-bound organelles. They typically have ribosomes and some other structures, but these are not enclosed within membranes.
Eukaryotic Cells
- Nuclear Region: Eukaryotic cells have a well-defined nucleus, where the genetic material is enclosed within a nuclear membrane. This separation allows for more complex regulation of gene expression.
- Membrane-bound Organelles: Eukaryotic cells contain various membrane-bound organelles, such as mitochondria, endoplasmic reticulum, and Golgi apparatus, which perform specialized functions within the cell.
Correct Option - C
The correct answer is option 'C': "Prokaryotic Cell - Nuclear region not well defined." This statement accurately describes the nature of prokaryotic cells. They do not have a true nucleus, which is a hallmark of eukaryotic cells.
In summary, understanding the differences between prokaryotic and eukaryotic cells helps clarify their structural and functional complexities, demonstrating why option 'C' is the only correct match.
