2. Chapter 10 The Cell Is The Basic Unit Of Life.

3. The Compound Microscope

4. Characteristics of Life All organisms: * 1.) grow * 2.) move – Change in place or position * 3.) respond to Stimuli * 4.) reproduce 5.) take in or produce their own food 6.) made-up of cells 7.) have a special chemical make-up

5. Cells Cells are the basic units of life Smaller unit of life Functional System

6. Cells The Cell Theory: 1.)The cell is the basic unit of life 2.)All living things are made up of one or more cells. 3.)All cells come from other living cells.

7. Mitosis Cell division in body (somatic) cells. Skin, bone, and other body cells divided to heal cut or injured cells. One cell divided into two new cells every four to five hours.

8. Meiosis Cell division in sex cells (Gametes)

9. Organelles: (p.405) Cell Wall Cell Membrane Chloroplast Cytoplasm Nucleus Vacuole Mitochondria

10. Plant Cells

11. Animal Cells

12. Differenced between Plant and Animal Cells 1.) Plant cells have chloroplasts. 2.) Plant cells have cell walls, therefore they have a regular shape. 3.) Plant cells have fewer, and larger, vacuoles.

13. Chapter 11 Human Body Cells Are Organized As Tissues, Organs, and Systems.

14. The Levels of Organization found in All Living Thing 1.)Cells - 2.)Tissue - 3.)Organs - 4.)Organ Systems - 5.)Organisms -

15. The Characteristics of Systems Made up of individual parts that work together as a whole. Often connected to one or more other systems If one part of the system is missing or damaged the whole system will not function well or not function at all.

16. Cells and Organisms Require The Same Basic Necessities of Life 1.)Oxygen 2.)Nutrients 3.)Waste Removal
