The correct answer is B. Lack of a nucleus.
Bacteria are prokaryotic cells, which means they do not have a defined nucleus. In contrast, both fern leaf cells and human cheek cells are eukaryotic, meaning they have a nucleus that houses their genetic material. This is the key distinguishing feature when comparing these types of cells.
