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 true-nucleus, Eukaryotic cells do have a true-nucleus.
• Prokaryotic cells are plant cells and Eukaryotic cells are animal cells.

The main function of a 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.

The cytoplasm

• Is  the gel-like fluid that holds other organelles in place.
• Breaks down food to produce energy for the cell.
• Is known as the "brain" of the cell.
• Is where photosynthesis takes place.

Which statement is NOT part of the Cell Theory?

• Only animals are made of cells.
• Cells are the basic unit of structure and function in all living things.
• All living things are made of cells.
• New cells come from existing cells.

Ribosomes are the cell organelle that

• Break down food to produce energy for the cell.
• Produce proteins for the cell.
• Break down broken cell parts.
• Make food for the cell using the sun's energy.

Organisms composed of many cells are called
