Cells to Organisms What do we already know?

• What do you know about plant and animal cells?
• Trillions of cells in your body
• Each has different organelles
• All cells have a nucleus
• How are plant and animal cells different or the
  same?
• Animal cells flex and plant cells are firm
• Plant cells have chloroplasts
• Do you think all animals have the same cells?
• Im not sure
