2. Do Now (Seriously though, 5 minutes) Title: Organelles Pt. 2 Write in LT, BAME, Evidence, and How I can Improve DO NOW: A mystery cell has a cell wall. What additional evidence would you need to determine if the cell is prokaryotic or eukaryotic?

3. NORM As a class, we will work towards this  We ask questions to help us understand

4. Agenda  Do Now  Book Keeping  Organelle Function  Organelle Structure  Wrap Up

5. Book Keeping  Classroom Policy Change  Study Sessions After School

6. Organelles Defn: Structures within a cell that performs a specific function Like tiny organs for a cell Think of our cell as a factory

7. OrganelleFunction Eukaryotic cell organelles (structure / function)

8. Plasma (cell) Membrane  Gate Keeper”  Physical & chemical boundary of all cells  A double layer called the phospholipid bilayer. It is selectively permeable (semipermeable) meaning only certain things are let in and out

9.  Control center of cell (controls all cellular activities)  Contains DNA  Contains nucleolus Nucleus

10. Nucleolus  Located inside of the nucleus  Contains RNA and proteins  Makes ribosomes

11. Nuclear membrane/ Nuclear envelope  Double-layered membrane enclosing the nucleus of a cell.

12. Ribosomes  Sites of protein synthesis Proteins are the main product produced by the cell  Not considered a membrane- bound organelle  Found in prokaryotes and eukaryotes

13. Endoplasmic Reticulum  Helps move substances within cells  Network of interconnected membranes  Two types Rough endoplasmic reticulum Smooth endoplasmic reticulum

14. Rough Endoplasmic Reticulum  Ribosomes attached to surface Manufacture proteins Not all ribosomes attached to rough ER  May modify proteins from ribosomes

15. Smooth Endoplasmic Reticulum  No attached ribosomes  Has enzymes that help build molecules Carbohydrates Lipids

16. Golgi Apparatus  Involved in packaging and secretion of proteins The cellular post office  Also called golgi body

17. Mitochondria  Where energy for the cell is made (ATP)  Site of cellular respiration

18. Lysosomes  Found in animal cells Digest and recycle worn out cell parts Destroy foreign invaders

19. Plant cell only  Large vacuoles for storage of water and sugars  Cell wall made of cellulose for support and protection  Chloroplasts Where photosynthesis happens (glucose is made from water, CO2, & sunlight) Filled with chlorophyll, which gives green color

20. Cytoplasm  Viscous fluid containing organelles  Components of cytoplasm Interconnected filaments & fibers Fluid = cytosol Organelles

21. Cytoskeleton  Made of 3 fiber types Microfilaments Microtubules Intermediate filaments  3 functions: mechanical support anchor organelles help move substances

22. Cilia & Flagella  Provide motility  Cilia Short, hair-like extensions  Flagella Whip-like extensions

23. Centrioles  Pairs of microtubular structures  Play a role in cell division

24. Matching Organelle to its Function  Working with your elbow partner  Cut out the Functions and Memory Items  Match the function and memory item with the correct organelle  You BOTH must agree before you glue them on

25. We ask questions to understand  Think about the learning targets we have investigated  What questions do you have?  Should I address these in class?  Should I address these afterschool?

26. Self-Assess LT (5 minutes) BAME I have little to no understanding of the learning target. I have some understanding of the learning target. I have a solid understanding of the learning target. I have a solid understanding of the learning target and I am able to help my peers have a solid understanding

27. Wrap Up Coming Up  Cell Structure (Organelles)  Work with Microscopes Important Reminders  Lab Safety Contract!  Quiz on Microscopes, 8 Characteristics of Living Things, and Cells on Friday 10/16/2015
