  1. Today’s Agenda… • Bellringer: (Review) What is the difference between a mixture and a compound? Give an example of each. • Card Sort • Notes on Organization of Organisms • Exit Slip

  2. The Organization of Organisms Study Pack #7

  3. Today’s Goal… • I can describe the levels of organization within an organism.

  4. Before we begin… • Card Sort • Work with your partner to put the cards in order from simplest (or smallest) to most complex (or largest) • Discuss why you have chosen this order

  5. Cell Teamwork • For unicellular organisms the single cell performs all life functions • Bacteria

  6. Cell Teamwork • In multicellular organisms cells have special functions and work together for the good of the organism • Plants • Animals

  7. Levels of Organization • Cells • Tissues • Organs • Organ Systems • Organisms

  8. Cells • Basic unit of structure and function in living things • Serve a specific function • Examples • Blood cells • Muscle cells • Bone cells • Brain cells How do you think these cells are different in structure and function?

  9. Tissues • Made up of similar cells that work together • Examples • Epithelial (skin) tissue • Connective (tendons, ligaments) tissue • Muscle tissue • Nerve tissue

  10. Organs • Made up of tissues that work together • Examples • Heart • Brain • Skin

  11. Organ Systems • Two or more organs that work together • Examples • Skeletal System • Muscular System • Nervous System

  12. Organisms • Living things • However, living things may also just be made up of one cell (bacteria)

  13. CELLS TISSUES ORGANS ORGAN SYSTEMS ORGANISMS

  14. One More Step! • What makes up cells? • Organelles • What makes up organelles? • Molecules - atoms bonded together • What makes up molecules? • Atoms (elements from the periodic table)

  15. Put these in order… • From simplest to most complex • Organ • Cell • Organism • Tissue • Organ system • Organelle
