1. Bell Work Draw a jail cell Draw an apartment complex or resort
How are these like a plant cell?
Cell Wall
Nucleus
Vacuole
Chloroplast

2. Cells may be the basic unit of life …but we didn’t always know about them.

3. Development of Cell Theory

4. Zacharias Jansen 1595 - Developed the first compound microscope
Allowed for greater magnification

5. Robert Hooke 1665 – Looked at cork under a microscope.
First to use the term “cells”
Looked like tiny cells/rooms in a monastery.

6. Anton van Leeuwenhoek
1674 – Discovered tiny organisms living in water. “animalcules”
The “Father of Microbiology”
Tiny organisms exist that we can’t see.
Even in the water we drink.

7. Matthias Schleiden
1838 – Determined plants are made of cells.

8. Theodor Schwann
1839 – Determined animals are made of cells.

9. Rudolph Virchow
1855 – All cells come from other existing cells

10. Three Points of Modern Cell Theory
All living things are made of cells.
Cells are the basic units of structure and function in living things.
New cells come from other cells.
The Weird History of Cell Theory

12. Prokaryote
Eukaryote

13. Unique Characteristics of Prokaryotes
Means “before nucleus”
All single celled organisms
DO NOT have a nucleus to contain their DNA
Very few internal structures
All bacteria are prokaryotes
Unique Characteristics of Prokaryotes

14. Unique Characteristics of Eukaryotes
Means “true nucleus”
Have a nucleus
Complex structure – many internal structures (organelles)
Can be a single cell or multicellular organisms
All animals and plants are Eukaryotes

15. Shared Characteristics
They have a Cell Membrane
Contain DNA
They show all characteristics of life
Shared Characteristics

16. Major Types of Cells
All Cells
Prokaryotes
Eukaryotes
