The best-supported conclusion based on the evidence provided is:
The first cell is a eukaryotic cell, and the second cell is a prokaryotic cell.
Explanation:
- Eukaryotic cells are characterized by having a nucleus and organelles such as mitochondria, which are present in the first cell.
- Prokaryotic cells, such as bacteria, lack a nucleus and often have a cell wall made of peptidoglycan, which describes the second cell.
