10. Scientists and the Cell Theory

11. Hans & Zacharias Janssen 1590 Father and Son Produced first compound microscope

12. Anton van Leeuwenhoek • Born: October 24, 1632 • Died: August 30, 1723 • He is known as the “Father of Microscopy.” http://en.wikipedia.org/wiki/Anton_van_Leeuwenhoek

13. 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 http://www.kent.k12.wa.us/staff/TimLynch/sci_class/chap09/lesson_protista/Protista_Lesson.html#Algae

14. Robert Hooke • Born: July 18, 1635 • Died: March 3, 1703 • Wrote and published “Micrographia” • Known as the “English Father of Microscopy” http://www-groups.dcs.st-and.ac.uk/~history/PictDisplay/Hooke.html

15. Robert Hooke Contributions: - He observed pieces of cork from the bark of a cork tree under the microscope. - His observations led him to coin the word “cell.” - “Cell”- means little rooms in Latin - He compared the small boxes to the small rooms that monks lived in. http://www.learner.org/channel/courses/essential/life/session1/closer1.html

16. Matthias Schleiden • Born: April 5, 1804 • Died: June 23, 1881 • German botanist • Discovered that all plants were made of cells • Contributed to the creation of the cell theory http://www.britannica.com/eb/article-9066147/Mathias-Jacob-Schleiden

17. Theodor Schwann • Born: December 7, 1810 • Died: January 11, 1882 • German zoologist • Concluded that all animals are made of cells. • Contributed to the creation of the cell theory http://www.nndb.com/people/357/000096069/

18. Rudolph Virchow • Born: October 13, 1821 • Died: September 5, 1902 • German pathologist • He is known as the “Father of Pathology.” • Discovered that all living cells come only from other living cells. http://en.wikipedia.org/wiki/Image:Rudolf_Virchow.jpg

19. The Cell Theory • Major Contributors: • Matthias Schleiden • Theodor Schwann • Rudolph Virchow

20. 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.

21. Characteristics ofLiving Things(Mr. Fadrug) • M made of cells • R reproduce • F food or raw materials • A adapt • D develop • R respond • U use energy • G grow

22. Cells Tissues Organs Organ Systems Organisms

23. One Cell Simple Cannot See Without Microscope Examples: Bacteria, Amoeba Many Cells Working Together Complex Can See Without A Microscope Examples: Humans, Plants Unicellular vs. Multicellular

24. Cell Does NOT Have a True Nucleus Have NO Membrane-Bound organelles Oldest Type of Cells Example: Bacteria Cell Has a True Nucleus Has Several Membrane-Bound Organelles Tend to be Larger and More Complex than Prokaryotes Examples: Human, Plants and Animals Prokaryote vs. Eukaryote

25. Animal Cell

26. Plant Cell

27. Nucleus

29. Mitochondria

30. Golgi Apparatus / Bodies / Complex

33. Central Vacuole “Storage Bin” Cell Membrane “Gatekeeper” Cell Wall Plant Only Golgi Apparatus GA Cytoplasm Cell Ribosomes Organelles Mitochondria “Powerhouse” Nucleus “Boss” Lysosome Chloroplasts Plant Only Endoplasmic Reticulum ER

38. Function • Controls cell activities • Jellylike material that surrounds the nucleus • Releases energy from food • Make protein for the cell • Tubes through which materials move to all parts of the cell • Controls the flow of materials into and out of the cell • Breaks down worn parts of the cell • Stores food, water, minerals and waste • Thick outer covering of plant cells • Structures in cells which contain chlorophyll Match Function With Cell Parts Parts of Cells Cell Membrane Cytoplasm Endoplasmic Reticulum Mitochondria Nucleus Ribosomes Cell Wall Lysosome Chloroplasts Vacuole
