A
Mitochondria
B
Nucleoid region
C
Endoplasmic reticulum
D
Golgi apparatus
Verified step by step guidance
1
Begin by understanding the basic differences between prokaryotic and eukaryotic cells. Prokaryotic cells are simpler and lack membrane-bound organelles, while eukaryotic cells have complex structures with organelles.
Identify the organelles listed in the problem: mitochondria, endoplasmic reticulum, and Golgi apparatus. These are all membrane-bound organelles typically found in eukaryotic cells.
Recognize that prokaryotic cells do not have a nucleus. Instead, they have a nucleoid region where their genetic material is located. This is a key feature distinguishing them from eukaryotic cells.
Understand that the nucleoid region is not a membrane-bound structure, but rather an area within the prokaryotic cell where the DNA is concentrated.
Conclude that the nucleoid region is the feature most often found only in prokaryotic cells, as the other options are organelles characteristic of eukaryotic cells.
