1. 10/22 Daily Catalyst Pg. 37 Cell Theory
1. There are 100 students in a class. Twenty-two did well in the course whereas 78 blew it totally and received a grade of F. Sorry. In the highly unlikely event that these traits are genetic rather than environmental, and if the four (78%) represent the frequency of the homozygous recessive condition, please calculate the following:
A. The frequency of the recessive allele.
B. The frequency of the dominant allele.
C. The frequency of heterozygous/hybrid individuals.

???

8. The Scientists of the Cell Theory

9. Anton van Leeuwenhoek Born: October 24, 1632 Died: August 30, 1723
He is known as the “Father of Microscopy.”

10. Anton van Leeuwenhoek Discoveries:
- 1673: He looked at pond scum under the microscope and discovered small organisms he called animalcules or little animals (Protists)
- 1676: discovered bacteria

11. Robert Hooke Born: July 18, 1635 Died: March 3, 1703
Wrote and published “Micrographia”
Known as the “English Father of Microscopy”

12. Robert Hooke Contributions:
- Key Point #2: coined the term the “cell”.
He observed pieces of cork from the bark of a cork tree under the microscope.
- His observations led him to popularize the word “cell.”

13. Matthias Schleiden Born: April 5, 1804 Died: June 23, 1881
German botanist
Key Point #3: Discovered that all plants were made of cells

14. Theodor Schwann Born: December 7, 1810 Died: January 11, 1882
German zoologist
Key Point #4:Concluded that all animals are made of cells.

15. Rudolph Virchow Born: October 13, 1821 Died: September 5, 1902
German pathologist
He is known as the
“Father of Pathology.”
Key Point #5: Discovered that all living cells come only from other living cells.

16. The Cell Theory Major Contributors: Matthias Schleiden Theodor Schwann
Rudolph Virchow
Star by their name

17. Key Point # 6: The Cell Theory
All living things are made of cells.
Cells are the basic units of structure and function in living things.
Living cells come only from other living cells.

18. Don’t Forget!
Review Redi’s experiment.

19. Pg. 38 Eukaryotes

20. What do the following have in common?
All of the following are made of cells.

21. Review Time
Life
Prokaryotes
Eukaryotes

22. Blocks
Cells are like blocks. Each block is stacked upon one another to make something. All of the blocks together make a tower or house. The cells in our body are like the blocks. The cells make up our organs and the organs make up our body. Cells are tiny and cannot by seen unless you have a powerful microscope.

23. Eukaryotes Examples? Plants and animals.
Now there are similarities between us and plants if you can believe it!

24. Eukaryotic Cells Plant Animal
Plant and animal cells are both eukaryotic cells. This means both cells hae a true nucleus and they also contain membranes around certain organelles.

25. Life can be divided into two categories:
Key Point #1: Eukaryote
Eu: True
Karyote: Nucleus

26. Eukaryotes are bigger and more complicated
Organelles
Chromosomes
Multicellular
Animal and plant cells

27. Key Point #2: Euks contain membrane-bounded organelles
Mini “organs” that have unique structures and functions
Located in cytoplasm

28. Organelles Work Time

2. What is the nickname for the ribosomes?
3. What was Hooke observing when he coined the term “cells”?

32. Exit Ticket #6 Cells
