Interpretation: The prokaryotic cells, thought to be more ancient than eukaryotic cells, is to be explained.
Concept introduction: Organisms might consist of a single or billion cells. Prokaryotic and eukaryotic cells are the two kinds of cells found in nature.

Answer to Problem 93A
Prokaryotic cells are assumed to be more ancient than eukaryotic cells due to the complexity of their structures. The structure of prokaryotic cells is simpler than eukaryotic cells.
Explanation of Solution
Prokaryotic cells do not include a nucleus and do not have organelles that are surrounded by a membrane. On the other hand, eukaryotic cells are distinguished by their presence of a nucleus and organelles surrounded by membranes. It is believed that prokaryotic cells are more ancient than eukaryotic cells because of the difference in the complexity of their structures. Prokaryotic cells have a simpler structure than eukaryotic cells.
