1. Biology Discussion Notes Monday 11/17/2014

2. Goals for the Day 1.Draw the most basic evolutionary tree 2.Distinguish between a prokaryote and a eukaryote 3.Be able to name the 3 parts of the cell theory 4.List the 5 cell parts that all cells have

3. Question of the Day 11/17 What is the basic unit of life? (What do all living things contain) What type of factor (think ecology) contains these things?

4. Phylogeny of Life All living things contain cells, but not all cells are alike.

5. Types of Cells Origin of the words Prokaryotes: –I say “PRO” you say………. Eukaryotes: –I say “Eu” you say…………..

6. Types of Cells There are 2 main types of cells that correlate to the two main groups of life Prokaryotes: include bacteria & archea –All prokaryotes have prokaryotic cells

7. Prokaryotes Always have: Circular DNA Often have: cell wall cilia or flagella Chapter 3

8. Prokaryotes Single-celled Lack(do not have) nucleus Membrane-bound organelles Chapter 3

9. Types of Cells There are 2 main types of cells that correlate to the two main groups of life Eukaryotes: includes animals, plants, fungi, and protists –All eukaryotes have eukaryotic cells

10. Eukaryotic Cells –All Eukaryotic cells Contain: Nucleus – contains DNA membrane bound organelles

11. Phylogeny of Life All living things contain cells, but not all cells are alike.

12. Draw the basic phylogeny of living things

13. Phylogeny of Life All living things contain cells, but not all cells are alike.

15. Take a minute: In your notes, draw a prokaryotic cell and a eukaryotic cell. Label the types of organisms that would have each type of cell.

16. What differentiates Prokaryotic & Eukaryotic cells? Cell Size Write a prediction about cell size of prokaryotes & eukaryotes in your notes.

17. The Cell Theory 1.All living things are made of one or more cells. 2.Cells are the basic units of structure and function in organisms. 3.All cells arise from existing cells.

18. Common Features of Cells Cells share common structural features, including: Cell membrane-an outer boundary of the cell Cytoplasm-interior substance of the cell Cytoskeleton-structural support for the cell DNA –form of genetic material Ribosomes- cellular structures that make proteins

19. Test Corrections Re-write question and then the correct answer. –It should read as a complete statement. When finished work on next slide

20. 1.What do you want to know about cells? 2.What do we know about all of these organisms because they are living things? –Use our biology vocabulary to describe living things, go through your notes, something from each chapter. –Come up with a list of 5 things on your own –Then work with a partner to come up with a list of 15.

21. What we know about all living things:

22. Species of the day 11/17 Olive Baboon Papio anubis Is this baboon a prokaryote or a eukaryote? What cell parts do you know it has?
