Explain Bot To find the best description of a difference between prokaryotic and eukaryotic cells, we need to understand what each type of cell is.
Prokaryotic cells are found in bacteria and archaea. They are simpler in structure, lacking a distinct nucleus and membrane-bound organelles. Their genetic material is contained in a single circular molecule of DNA, known as a nucleoid.
On the other hand, eukaryotic cells are found in plants, animals, fungi, and protists. They are more complex and have a nucleus that houses their genetic material. Eukaryotic cells contain membrane-bound organelles, such as mitochondria, endoplasmic reticulum, and Golgi apparatus.
Now, let's examine the provided options and determine the best description:
A. Prokaryotic cells have a nucleus, while eukaryotic cells lack a nucleus.
This option is incorrect as it states the opposite of the actual difference. Prokaryotic cells lack a distinct nucleus, whereas eukaryotic cells have a nucleus.
B. Prokaryotic cells have membrane-bound organelles, while eukaryotic cells lack membrane-bound organelles.
This option is incorrect as it also provides an inaccurate statement. Prokaryotic cells lack membrane-bound organelles, whereas eukaryotic cells contain various membrane-bound organelles.
C. Prokaryotic cells lack genetic material, while eukaryotic cells have genetic material.
This option is incorrect as it states that prokaryotic cells lack genetic material, which is not true. Both prokaryotic and eukaryotic cells have genetic material, but they differ in how it is organized.
D. Prokaryotic cells are smaller in size than eukaryotic cells.
This option is the most accurate and provides the best description of a difference between prokaryotic and eukaryotic cells. Prokaryotic cells are generally smaller in size than eukaryotic cells.
Therefore, option D is the correct answer.
