Answer
This single-celled organism is most likely based on size alone. The organism is 10 μm in diameter and falls into the range of a eukaryotic cell.
Work Step by Step
Based on size alone, this single-celled organism is most likely eukaryotic.
Prokaryotic cells are typically 1 to 5 μm in diameter. Eukaryotic cells are bigger, ranging in diameter from 10 to 100 μm. Therefore, this organism is 10 μm in diameter and falls into the range of a eukaryotic cell.
