3 Introduction to Cells

4 Discovery of the cell 1665-Robert HOOKE saw the cell walls of cork and called them CELLS 1665-Robert HOOKE saw the cell walls of cork and called them CELLS

5 1673 Anton van LEEUWENHOEK saw the first living cells in a drop of water – little animals

6 3 Discoveries that led to the Cell Theory 1838 Matthias SCHLEIDEN concluded all plants were composed of cells 1839 Theodor SCHWANN concluded all animals were composed of cells 1855 Rudolf VIRCHOW observed cell division.

7 The Cell Theory (3 parts) All living things are composed of cells Cells are the basic units of structure and function in an organism Cells come only from the reproduction of existing cells

8 Cell Diversity Not all cells are alike Not all cells are alike Sizes and shapes vary for structure and function Sizes and shapes vary for structure and function

9 1/11/12 Do-Now: Complete the GRECHO warm up on the back of your Cell Theory Notes from Yesterday. Do-Now: Complete the GRECHO warm up on the back of your Cell Theory Notes from Yesterday. 1.

10 1/11/12- Do-Now: Do-Now: 1. We have discussed 5 scientists so far. List their names & what they did. 2. List the 3 parts of the cell theory. 3. What do the following prefixes/suffixes/roots mean? a. Uni-b. Multi-c. Pro-d. Eu- e. Auto-f. Hetero-g. Bio-h. –ology Set your homework (vocab wkst. and your directed reading) on your desk to be checked.

11 Cells contain a variety of internal structures called ORGANELLES. ORGANELLE –a cell component that performs specific functions for the cell

12 The 2 main types of cells: PROKARYOTES- PROKARYOTES-cells without a nucleus or membrane-bound organelles, have circular genetic material Bacteria are the ONLY examples

13 Types of cells, cont. EUKARYOTES – cells that have a nucleus and membrane bound organelles. Plants, animals, protists & fungi are examples

What are the three parts of the cell theory? What are the two main types of cells? What are the two main types of cells?

16 8/12/11 Do-Now: Have out the Prefix/Suffix/Root vocabulary on your desk. Do-Now: Have out the Prefix/Suffix/Root vocabulary on your desk. 1. Contrast prokaryotes & eukaryotes. List an example of each. 2. What do the following prefixes/suffixes/roots mean? a. Uni-b. Multi-c. Pro-d. Eu- e. Auto-f. Hetero-g.
