Cell theory was first proposed in 1838. Evidence obtained through additional scientific investigations resulted in the current cell theory. Which statement describes a component of the original cell theory that was removed because of the new scientific knowledge?

•  All living things are made of cells
• All cells come from other preexisting cells
•  Cells form through spontaneous generation.
• Cells are the basic structural and functional units of life
