The cells that Marlene is observing, which are round, simple, and lack complex membrane-bound structures, are most likely prokaryotic cells. Prokaryotic cells are characterized by their simplicity and lack of membrane-bound organelles, such as a nucleus or mitochondria. They are typically smaller and less complex than eukaryotic cells, which have a true nucleus and other membrane-bound organelles.
