Final answer:
Bacterial cells are not examples of eukaryotic cells because they lack membrane-bound organelles and a nucleus, classifying them as prokaryotic.
Step-by-step explanation:
Among the organisms studied microscopically in BABS1201, bacterial cells are not an example of eukaryotic cells. Eukaryotic cells have complex structures called organelles that are surrounded by membranes. These include the nucleus, mitochondria, endoplasmic reticulum, and others. Plant cells, animal cells, and fungal cells all have these membrane-bound organelles and are classified as eukaryotic. Conversely, bacterial cells lack these organelles; they do not have a nucleus and instead have their genetic material in a nucleoid region. This lack of a nucleus and membrane-bound organelles classifies them as prokaryotic cells, distinct from eukaryotes.
