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?

• A.   All living things are made of cells.

• A.   All cells come from other preexisting cells.

• A.   Cells form through spontaneous generation.

• A.   Cells are the basic structural and functional units of life

• X-rays

• computers

• the light microscope

• the telescope
