1 Chapter 17 Cells: The Basic Unit of LIFE

2 1. Organization-cell-basic unit of all living organisms 3. Homeostasis-balance-equilibrium 4. Movement (Biological)-locomotion 2. Metabolism-biochemical activity to build up or break down material 5. Growth and repair 7. Response to a stimulus 6. Reproduction-(asexual, cellular), (Sexual, new species) 8. Adaptation-a change over time

3 The Diversity of Cells Working in pairs develop a flow chart describing the discovery of cells and the cell theory. Use the following dates to guide your discovery (1665, 1673, 1838, 1839, 1858), include the scientists and their discovery.

4 Anton van Leeuwenhoek Saw protists in pond scum Bacteria and single-celled organisms Robert Hooke Built first microscope Saw little rooms called cells Mathias Schleiden All plant parts are made of cells Rudolf Virchow All cells come from existing cells Theodor Schwann All organisms are made of one or more cells Basic unit of all living things

5 Cells Cell-the smallest unit that can carry on life sustaining processes Parts in common- –Cell Membrane –Cytoplasm Organelles –Nucleus

6 Two Kinds of Cells Prokaryotes Do not contain a nucleus EubacteriaArchaebacteria Single-celled Bacteria No Nucleus but DNA Ribosomes Cell Wall and Cell Membrane Bacteria Live Everywhere Heat-loving, salt- loving, methane- making Cell Wall and Cell Membrane are different from other cells Ribosomes are similar to Eukaryotic Cells Archea

7 Eukaryotic Cells Organelles-structures that perform specific functions within the cell Eukaryotes Contain a nucleus

8 Surface Area-to- Volume Ratio Lets Practice… Turn to page 500. Read through the Math Focus box. Complete questions 1-4. How does this connect with the study of cells?
