1.
Cell Theory<br />& Types of Cells<br />

2.
Cell Theory<br />All living things are made up of one or more cells and their products<br />

3.
Cell Theory<br />The cell is the simplest unit that can carry out all life processes.<br />

4.
Cell Theory<br />All cells come from other cells; they do not come from non-living matter<br />

5.
Classification of Cells<br />

6.
Prokaryotic Cells<br />simple, unicellular organisms (e.g. archaea and bacteria)<br />no cell nucleus<br />no membrane-bound organelles<br />

7.
Prokaryotic Cells<br />archaea<br />e. coli bacteria<br />

8.
Eukaryotic Cells<br />much larger than prokaryotic cells<br />contain a nucleus and other membrane-bound organelles<br />includes all protists, fungi, animals, and plants<br />

Single-Celled Eukaryotes<br />amoeba<br />

Single-Celled Eukaryotes<br />

12.
Multi-cellular Organisms<br />Multi-cellular eukaryotes can be further classified into plant cells and animal cells<br />plant cell<br />animal cell<br />

Plant Cells<br />

15.
Animal Cells<br />

16.
Specialized Cells<br />Eukaryotic organisms:<br />

17.
Specialized Cells<br />Complex organisms contain many different types of cells that perform different functions<br />Specialized cells have physical and chemical differences that allow them to perform one job very well<br />

18.
Specialized Plant Cells:transport cells (xylem & phloem)<br />

19.
Specialized Plant Cells:storage cells (amyloplasts)<br />

20.
Specialized Plant Cells:photosynthetic cells (contain many chloroplasts)<br />

21.
Specialized Plant Cells:root cells (epidermal)<br />

22.
Specialized Plant Cells:guard cells (stomata)<br />

23.
Specialized Animal Cells:Blood cells<br />

24.
Specialized Animal Cells:Skin cells<br />

25.

26.
Specialized Animal Cells:Muscle cells<br />

27.
Specialized Animal Cells:Gamete cells (sperm & egg)<br />

28.
Specialized Animal Cells:Fat cells<br />

29.
Specialized Animal Cells:Nerve cells (neurons)<br />

30.
Specialized Animal Cells:Rods & cones<br />
