Aim # 42: What is the cell theory?
HW:
Test next Thursday on Life Functions, Microscopes, Cell Theory and Organelles 
Do Now:
What do we call living things that are made up of one cell?
What do we call living things that are made up of many cells?

2. I. Main Ideas of Cell Theory
Cell Theory states that
All living things are made of cells
Name any living thing, I’ll show you its cells

3. 2. Cells are the basic units of structure and function in organisms
Structure and function are related

4.
CNIDOCYTE
NERVE CELL
EPIDERMAL CELL

5. GUARD CELL SPERM CELL
EGG CELL

6. 3. All cells come from preexisting cells Cell Division

7. Anton Van Leeuwenhoek 1600s
Developed simple light microscopes that allowed him to examine tiny living organisms he called “animacules”

8. Robert Hooke 1665 What is this? Cork Cells First compound microscope
First person to use the word “cell”

9. Matthias Schleiden 1838
ALL PLANTS ARE MADE UP OF CELLS!!

10. Theodor Schwann 1838
ALL ANIMALS ARE MADE UP OF CELLS!!

11. Rudolf Virchow 1858
CELLS COME FROM PRE-EXISTING CELLS!

12. A Brief History of Cells

13. II. Basic Types of Cells
All cells contain organelles: specialized structures that carry out life functions
Many organelles have a membrane

14. Prokaryotes: cells that do not contain membrane-bound organelles
Most unicellular organisms are prokaryotic cells (bacteria, archaea)

15. Smaller, less complex
The first cells were prokaryotes

16. 2. Eukaryotes: cells that contain membrane-bound organelles
Some unicellular and all multicellular organisms are made of eukaryotic cells (protists, fungi, plants, and animals)

17. Larger, more complex
Most importantly, eukaryotes contain a nucleus: the central membrane-bound organelle that controls cell function

18. IV. Multicellular Organization
Organelles make up cells
Cells make up tissue
Tissue make up organs
Organs make up organ systems
Organ Systems make up organisms
