1. Objectives • Students will discuss the development of cell theory. • Students will be able to discriminate between living and non-living things. • Students will draw and animal and plant cell and label it’s parts. • Students will make a foldable of the organelles of both and practice naming them on an unmarked poster. • Students will practice explaining the function of these organelles.

2. Today you need:pencil, markers or colored pencils, paper for notes, 2 pieces of big white paper. Vocabulary: Cell cell theory Nucleus Eukaryote Prokaryote

3. Cell Structure & Function http://koning.ecsu.ctstateu.edu/cell/cell.html

4. What’s a cell? A cell is the smallest unit that is capable of performing life functions.

5. Cell timeline

6. Hooke’s Cell Theory • All living things are made up of cells. • Cells are the smallest working units of all living things. • All cells come from preexisting cells through cell division.

7. Are they made of cells? • people? • cats? • tomatoes? • Mushrooms? • Bacteria? • The desk? • Your pencil?

8. Examples of Cells Amoeba Proteus Plant Stem Bacteria Red Blood Cell Nerve Cell

9. Can you guess what the 5 groups of living things things are? Animals Plants Fungus Protists Bacteria

10. organelles • “little organs” • Membrane (skin) bound structures inside the cell. • Different in each kind of cell • All have different functions or jobs

11. Two Types of Cells Prokaryotes Eukaryotes • No organelles • No nucleus • Bacteria only • Evolved first • Small and simple • Single celled • Have organelles • Have a nucleus • All others (animals, plants, fungus and protists) • Evolved later • More complex

12. Let’s draw some cells….We are going to draw a colored plant and animal cell, label all the organelles and learn what each of them do!
