Biology Cells

One of the main differences between prokaryotic and eukaryotic cells is that —

• eukaryotic cells have a smaller cell nucleus

• prokaryotic cells are always much larger

• prokaryotic cells do not have a plasma membrane

• eukaryotic cells contain membrane-bound organelles

What structure is common to all six kingdoms of living organisms?

• Cell wall

• DNA

• Nucleus

• Mitochondria

How is the prokaryotic bacterium in the diagram different from a eukaryotic cell? 

• It stores its genetic information in DNA.
• It has ribosomes to make proteins.
• It has a cell membrane.
• It has no membrane-bound nucleus.

Which of these statements best summarizes the cell theory?

• Cells must contain a nucleus and other parts.

• Cells were created by scientists in 1665.

• Cells can't be seen through a microscope.

• Cells are the building blocks of all living things.
