1. While You Are Waiting 12/8/16
What do you see?
What do you think?
What do you wonder?

2. Agenda for Thursday, December 8, 2016
While You Are Waiting - #4
Video Clip - Lysosomes
Notes: Organelles that Store, Clean up, and Support
Homework: Study the organelles and their functions

3. Lysosome Video Clip

4. Content Objective:
I will be able to compare cellular structures and their functions in eukaryotic cells

5. Organelles that Store, Clean up, and Support

6. Organelles that store, clean up, and support
Vacuoles, Vesicles, Lysosomes, and the Cytoskeleton
Vacuoles are large saclike structures that store materials like water, salts, proteins, and carbohydrates
Plants cells contain a large central vacuole that helps support heavy structures such as leaves
Some single celled organisms such as paramecia have contractile vacuoles that help pump out excess water

7. Paramecium

8. As compared to vacuoles, vesicles are smaller structures which store and move materials between cell organelles

9. As compared to vacuoles, vesicles are smaller structures which store and move materials between cell organelles

10. Lysosomes are small organelles filled with enzymes that break down lipids, carbohydrates, and proteins into small molecules that the cell can use
They also break down old organelles

11. Please remain in your seat until the bell rings

12. While You Are Waiting 12/9/16
Which organelle is involved in photosynthesis?
How might available sunlight, water or temperature affect the rate of photosynthesis? 1 2 3

13. Agenda for Friday, December 9, 2016
While You Are Waiting - #5 (I am collecting today)
Cytoskeleton Video Clip
Notes: Organelles that Support
Homework: Organelles in Eukaryotic Cells Sheet

14. Content Objective:
I will be able to compare cellular structures and their functions in eukaryotic cells

16. The cytoskeleton is a network of fibers and tubes that help the cell maintain its shape and allows certain organelles to move as well as certain cells to move

17. The cytoskeleton is a network of fibers and tubes that help the cell maintain its shape and allows certain organelles to move as well as certain cells to move
Cytoskeleton consists of microtubules- hollow protein structures
Cytoskeleton consists of microfilaments- threadlike structures made of proteins called actin

18. Microtubules help many cells maintain their shape, form centrioles which aid in cell reproduction, and form cilia and flagella which allow some single celled organisms to move
Microfilaments provide a flexible support for some cells and help other cells such as amoebas to move
