EOC Review 1

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.

Which invention from the 17th century allowed for the development of modern cell theory?

• X-rays
• computers
• the light microscope
• the scanning electron microscope

A plant and an animal are both living things. According to the Cell Theory, what can you conclude about these two very different organisms?

• Plants have cells but animals do not.
• They are both made of one or more cells.
• They both come from the same kind of cell.
• They both come from a non-living organism.
