Question Answer
ProkaryotesLack an organized nucleus; DNA is naked and sitting in cytoplasm
Eukaryotes Have well-defined nucleus
Prokaryotes category Bacteria; Cyanobacteria
Eukaryotes categoryAlgae, fungi, protozoa,plants and animals
ChromosomeProkaryotes: single DNA molecule in a closed loop; Eukaryotes:DNA packaged in multiple chromosomes; inside a nucleus with nuclear membrane
RibosomeProkaryotes:70s molecular weight all free in cytoplasm; Eukaryotes:both free and bound to ER
Endoplasmic reticulumOnly Eukaryotes have this, membrane system function in protein and lipid synthesis
Golgi bodyOnly Eukaryotes have this, receive product from ER then package them in vesicles
MitochondriaOnly Eukaryotes have this, have its own DNA and divide by itself; provide ATP
LysosomeOnly Eukaryotes have this, digestive enzyme fused with vesicles
