Presence of mitochondria and a well-defined nucleus
B
Lack of a membrane-bound nucleus and absence of membrane-bound organelles
C

D
Linear chromosomes and complex cytoskeleton
Verified step by step guidance1
Understand the key differences between prokaryotic and eukaryotic cells. Prokaryotic cells are simpler in structure and lack certain features found in eukaryotic cells.
Recall that prokaryotic cells do not have a membrane-bound nucleus. Their genetic material is located in a region called the nucleoid, which is not enclosed by a membrane.
Recognize that prokaryotic cells also lack membrane-bound organelles, such as mitochondria, chloroplasts, and the endoplasmic reticulum. These organelles are characteristic of eukaryotic cells.
Eliminate options that include features like mitochondria, chloroplasts, or a well-defined nucleus, as these are not present in prokaryotic cells.
Select the option that correctly identifies the defining characteristics of prokaryotic cells: 'Lack of a membrane-bound nucleus and absence of membrane-bound organelles.'
