Compare and contrast the characteristics of prokaryotic and eukaryotic cells
What will be an ideal response?
Prokaryotic cells have a nucleoid, a region within the cytoplasm where the DNA is found, but this region is not surrounded by a membrane. Eukaryotic cells, however, have a true nucleus that is surrounded by a nuclear membrane. Additionally, eukaryotic cells have a variety of membranous compartments known as organelles within the cell, whereas prokaryotes do not have membranous organelles. Prokaryotic cells tend to be smaller and less structurally complex in general than eukaryotic cells. Even though the two types of cells may have various structures in common, such as cell walls and flagella, these structures can vary widely in their molecular composition.
