What is the main difference between prokaryotic and eukaryotic cells?

• Prokaryotic cells have a nucleus and Eukaryotic cells do not
• Prokaryotic cells are unicellular and Eukaryotic cells are multicellular.
• Prokaryotic cells do not have a nucleus, Eukaryotic cells do have a nucleus.
• Prokaryotic cells are plant cells and Eukaryotic cells are animal cells.

The main function of chloroplasts is:

• To control what enters and leaves the cell.
• To break down food to release energy for the cell.
• To control all activities of the cell.
• To produce food for the cell using the sun's energy.
