prokaryotes: no membrane-bound organelles (no nucleus for instance)
eukaryotes: membrane-bound organelles (such as nucleus, ER, Golgi apparatus etc.)
there are two different types of cells: eukaryote and procaryotic. Procaryotic cells are unicellular (only have one cells), like bacteria.
organelles
Eukaryotic cells have organelles.
Eukaryotic cells contain organelles that are enclosed in membranes
Actually they were procaryotic cells. To be more exact, it is a scientific guess.
organelles
Prokaryotic cells lack a nucleus and other membrane-bound organelles, while eukaryotic cells have a nucleus and various organelles enclosed in membranes. Prokaryotic cells are generally smaller and simpler in structure compared to eukaryotic cells. Additionally, prokaryotic cells have circular DNA, while eukaryotic cells have linear DNA.
Organelles
Yes
Yes.
Eukaryotic
Eukaryotic cells have no organelles or a nucleus
