The correct options are
A Prokaryotes do not have a definite nucleus.
B Eukaryotes have membrane-bound cell organelles.
Prokaryotic cells are considered as primitive. They do not have a well defined nucleus and also lack membrane-bound organelles. Eukaryotic cells on the other hand, have a well-defined nucleus. All the membrane-bound cell organelles like mitochondria, golgi apparatus, etc are also present. Prokaryotic cells are smaller than eukaryotic cells. Cytoplasm is a structural component of a cell. It is present in all the cells.
