Objectives:
- Examine cell size.
Compare prokaryotic and eukaryotic cells.
Examine the development of the cell theory.

2. 75 to 100 trillion cells in the body
The smallest part of any living things that still counts as being “alive” is a cell! Is a leaf alive? How about your big toe? How about a drop of blood? Can we just keep dividing things into smaller and smaller parts, or is there a point at which what’s left is no longer alive? As you will see, there is such a limit, the smallest living unit of any organism is- the cell.
The average life span for a stomach cell is two days? A brain cell on the other hand, can live for a lifetime.

Write this down!!!
Cells are measured in microns or micrometers.
1 cm ->
1 mm ->
Metric
Inches
How Big is a Micron ( µ ) ?
1 mm = 1,000 microns

10. Typical cell can range from 5 – 100 microns.
So how big is a cell?
Typical cell can range from 5 – 100 microns.

11. Bacteria = 1 um
Animal cell = 10 um
Plant cell = 100 um
Hair = 100 um
How many _________ cells could fit across this strand of hair?

12. Let’s put size into perspective.

14. Types of Cells Prokaryotes and Eukaryotes
Review and correct your notes!

15. What are the two major types of cells?
Prokaryotic Cells
(Pre-Kernel)
Definition:
Size Range:
Domain: Bacteria, Archaea, Eukarya?
Examples:
Eukaryotic Cells
(True Kernel)
Definition:
Size Range:
Domain: Bacteria, Archaea, Eukarya?
Examples:

16. Prokaryotic Cells (Pre-Kernel)
Next Assignment What are the two types of cells? Create a T-Chart to compare and contrast them.
Prokaryotic Cells
(Pre-Kernel)
No membrane bound nucleus
.1 – 10 um (smallest)
Bacteria/Archaea
Examples: Bacteria
Basic Parts: Cytoplasm,
Nucleoid Region, Ribosomes,
Cell membrane

17. Next Assignment What are the two types of cells
Next Assignment What are the two types of cells? Create a T-Chart to compare and contrast them.
Eukaryotic Cells
(True Kernel)
Definition: Nucleus
Size Range: um (larger, more complex)
Domain: Eukarya
Examples: Plants and Animals

18. Review Scientists and The Cell Theory
Review and correct your notes!

19. The First Cells
Seeing is believing – Without the proper instruments, we didn’t know cells existed
1665 Robert Hooke: Compound Microscope
Slice of cork, a plant material
Looked like tiny empty chambers “cells”
Leeuwenhoek: Single-lens microscope
“Animalcules” = Bacteria

20. Development of The Cell Theory
Schleiden – All plants are made of cells
Schwann –
all animals are made of cells
Virchow – cells come from other cells

21. 1. All living things are made up of cells
* -- The Cell Theory -- *
1. All living things are made up of cells
2. Cells are the basic units in livings things.
3. New cells come from existing cells.

Why are cells small? Demo and Notes
Check color coding activity
Notes: Organelles and Microscopes
HW: Study vocabulary.

26. Warm-Up and Review!
1. The invention of the ____________ made the discovery of cells possible.
2. Robert Hooke used the name ______ to refer to the tiny empty chambers he saw when he observed magnified cork.
3. The two main types of cells we will be discussing in class are ___________ and ________.
4. The _________ __________ combines conclusions made by Schleiden, Schwann, and Virchow’s work.
5. A typical cell ranges from ________ to _______ in size.

27. Why do cells have to be so small?!

28. Surface Area to Volume Ratios
1. There are multiple chemical reactions that take place within a cell Larger the volume = The more reactions 2. The greater the surface area the more materials that can enter or leave at one time.

29. Surface Area to Volume Ratios
3. As a cell grows….. The Surface Area to Volume ratio decreases. The volume inside becomes bigger than the surface area.
4. At some point when growing…. The Surface Area becomes so small it can’t supply/get rid of materials effectively
5. At this point the cell cannot get larger.
This is why cells stay small!!!
