Respuesta :
The last one they have nuclei while bacteria have dna floating in the cytoplasm
Protists (algae) are single-celled eukaryotes. They are different from bacteria as they have nuclei in their cells, but bacteria lack distinct nuclei. Thus, option D is correct.
What are protists and bacteria?
Protists are the algae that belong to the eukaryotes and have a distinct nucleus or nucleus enclosed in the nuclear membrane. The nuclear membrane protects the nuclei from enzymes.
