  4. 1. Cells • Cells are the basic unit of all living things. • Different cells have different functions. • Examples: blood cells, bone cells and skin cells 1 http://www.manatee.k12.fl.us

  5. EXAMPLES OF CELLS dept.kent.edu/projects/cell/TM2.JPG www.turbosquid.com Blood Cell Muscle Cell Plant Epidermal Cell http://plantpath.ifas.ufl.edu

  6. 2. Tissues • Made up of many cells  (hint! Look for nuclei!) • A group of cells that work together to perform a specific job. • Examples: Blood, piece of muscle, and fat. 2 trc.ucdavis.edu

  7. Examples of Tissue Blood ?! Kidney tissue

  8. 3. Organs • Two or more tissues working together to perform a specific job. • Examples: stomach, intestines, heart 3

  9. Examples of Organs The Heart In a plant: a leaf

  10. Examples of Organs Skin!

  12. Here are some organ systems you should remember . . .

  13. Skeletal System • What are some of the functions of the skeletal system? • Protection of organs • Storage of minerals • Gives our body shape • Blood cell formation *http://www.stpeters.k12.nf.ca/skel.jpg
