Which of the following is a major difference between prokaryotic cells and eukaryotic cells?
A
Prokaryotic cells have a cell wall, while eukaryotic cells do not.
B
Prokaryotic cells have mitochondria, while eukaryotic cells do not.
C
Prokaryotic cells lack a nucleus, while eukaryotic cells have a nucleus.
D
Prokaryotic cells are larger than eukaryotic cells.
Verified step by step guidance
1
Identify the key structural differences between prokaryotic and eukaryotic cells. Prokaryotic cells are generally simpler and lack membrane-bound organelles, while eukaryotic cells have complex structures with organelles.
Understand that the presence or absence of a nucleus is a fundamental distinction. Prokaryotic cells do not have a nucleus; their genetic material is located in a nucleoid region. Eukaryotic cells have a defined nucleus that houses their genetic material.
Consider the presence of other organelles. Prokaryotic cells lack organelles such as mitochondria and chloroplasts, which are present in eukaryotic cells.
Evaluate the size difference. Prokaryotic cells are typically smaller than eukaryotic cells, which are larger and more complex.
Review the options given in the problem. The correct answer is the one that highlights the absence of a nucleus in prokaryotic cells and its presence in eukaryotic cells, which is a major distinguishing feature.
