Cell& Biochemistry EOC Review

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

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

• X-rays

• computers

• the light microscope

• the telescope

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

• A.     Plants have cells but animals do not.

• A.     They are both made of one or more cells.

• A.     They both come from the same kind of cell.

• A.     They both come from a non-living organism.
