Question 1

The reserve deposits of starch or other compounds found in many prokaryotic cells are called .

Accepted Answer

inclusions

Question 2

Compare and contrast the characteristics of prokaryotic and eukaryotic cells.

Accepted Answer

Prokaryotic cells have no nuclear membrane, whereas eukaryotic cells do have this membrane, thereby creating a nucleus containing their DNA. Eukaryotic cells have a variety of membrane- bounded compartments known as organelles; prokaryotes do not use these types of structures. Prokaryotic cells tend to be smaller and less 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 terms of their molecular composition.
