• All living things are made of cells; Cells are the basic unit of life; All cells come from pre-existing cells.

• Cells contain a nucleus; Cells are only found in animals; Cells do not divide.

• Cells are made of DNA; Cells can photosynthesize; Cells are only found in plants.

• Cells are always visible to the naked eye; Cells are made of water only; Cells do not reproduce.
