1. Cells Introduction Cell Theory, Prokaryotic vs Eukaryotic

2. Journal Entry (Name the organelle that best fits the description.) 0 1. Cell Control Center that contains DNA. 0 2. Allows materials to flow in and out of cell. 0 3. Supports and Protects the cell. 0 4. Makes usable energy for the cell. 0 5. stores food, water, and waste. 0 6. captures sunlight, to produce food. 0 7. Makes proteins. 0 8. clear jelly inside a cell. 0 9. makes ribosomes. 0 10. network of rods that maintains the cells shape

3. Prokaryotic Cell Labeling Underneath the diagram. Explain the difference between Prokaryotic and Eukaryotic. Why would a prokaryotic cell need something like a capsule?

4. The Cell Cell Theory and Scientist

5. Scientist 0 1665: Robert Hooke 0 Discovered and name cells 0 Leewenhoek: Discovered single cells through pond water. (single- lens microscope) 0 1830s: M. Schleiden 0 All Plants-made of cells 0 T. Schwann 0 All animals-made of cells 0 R. Virchow 0 Known for the Cell Theory

6. Cell Theory 0 Definition: The Cell Theory is one of the basic principles of biology. Credit for the formulation of this theory is given to german scientists Theodor Schwann, Matthias Schleiden, and Rudolph Virchow. 0 The Cell Theory states: 0 All living organisms are composed of cells. They may be unicellular or multicellular. 0 The cell is the basic unit of life. 0 Cells, Tissue, Organs, Organ Systems, Organism 0 Cells arise from pre-existing cells.

8. New Ideas 0 Energy flow occurs within cells. 0 Heredity information (DNA) is passed on from cell to cell. 0 All cells have the same basic chemical composition.

9. Draw a Venn Diagram on the next page. Eukaryotic vs Prokaryotic

10. Two Types of Cells 0 All living organisms can be sorted into one of two groups depending on the fundamental structure of their cells. 0 These two groups are the prokaryotes and the eukaryotes. 0 Prokaryotes are organisms made up of cells that lack a cell nucleus or any membrane-encased organelles. 0 Eukaryotes are organisms made up of cells that possess a membrane-bound nucleus (that holds genetic material) as well as membrane-bound organelles.

11. Anatomy of a Prokaryotic Cell 0 A typical prokaryotic cell might contain the following parts: 0 cell wall 0 plasma membrane 0 cytoplasm 0 flagella and pili 0 nucleoid 0 plasmid 0 Ribosomes

12. Anatomy of a Eukaryotic Cell A typical eukaryotic cell might contain the following parts: 0 plasma membrane 0 nucleolus 0 nucleus 0 chromosomes 0 rhibosome 0 vesicle 0 endoplasmic reticulum 0 Golgi apparatus 0 cytoskeleton 0 cytoplasm 0 lysosome 0 centrioles 0 mitochondria

15. All Cells HAVE! 0 1. DNA: the genetic material 0 2. PLASMA MEMBRANE: A phospholipid bilayer with proteins that separates the cell from the surrounding environment. 0 3. CYTOPLASM: The rest of the material of the cell. 0 4. RIBOSOMES: the organelles on which protein synthesis takes place.

17. Cell process – Synthesis of new molecules 0 Synthesis means “making” 0 What organelles are involved in making new molecules? 0 Nucleus (contains instructions to make proteins) 0 Ribosomes (make proteins) 0 Rough endoplasmic reticulum (synthesizes proteins) 0 Smooth endoplasmis reticulum (synthesizes lipids) 0 Golgi body (modifies molecules)

18. Cell Processes -- Homeostasis 0 Homeostasis is the maintenance of a stable internal environment. 0 Think of the organelles – which work together to perform homeostasis? 0 Cell membrane (lets out waste, transports in nutrients) 0 Cell wall (keeps cell shape) 0 Lysosome (digests waste) 0 Nucleus, ER, ribosomes, Golgi body (create new molecules needed to maintain homeostasis)

19. Tour of the Cell 0 1. You will be watching Paul Andersons Pod Cast on the cell. 0 This will review cell types, functions, and the major organelles. 0 This will take about 15 Minutes. 0 Homework: Cell Coloring Packet..Eukaryotic (animal and Plant), and Prokaryotic,
