If a student claims that new cells can form from non-living material, how would you use the cell theory to respond?

• The cell theory states that cells can form from non-living material.

• The cell theory states that cells come only from the reproduction of existing cells.

• The cell theory does not address cell formation.

• The cell theory states that cells can form from air.

Explain why the ratio between surface area and volume is important in limiting cell size.

• It determines how much energy the cell can produce.

• It affects how efficiently materials can move in and out of the cell.

• It controls the number of chromosomes in the cell.

• It decides the color of the cell.
