1. Cell Structure and Function
Organelles

2. Warm Up
In your journal, compare and contrast prokaryotic and eukaryotic cells. Use 2-3 complete sentences. Be prepared to share your responses.

3. ANALOGIES
An analogy recognizes how two different things can be alike in some way. People create analogies to help understand complex ideas. Review the following pictures and think about how the individual pieces contribute to the room’s overall function.

4. Relate functions to jobs

6. Relate functions to jobs

7. What is necessary for this cell to function?

8. ORGANELLES / SUB STRUCTURES
Cells must perform functions to survive. These functions occur in tiny structures (sub structures) called organelles found inside the cell.
Organelles are eukaryotic cell structures with specific functions. They enable cells to carry out different functions at the same time.

9. CELL MEMBRANE
Protects the cell by selectively allowing materials to enter and leave the cell.
Classroom analogy - door

10. Stores water and other liquids, food and waste.
VACUOLE
Stores water and other liquids, food and waste.
Classroom analogy - cabinet

11. Controls all cell activities, including reproduction.
NUCLEUS
Controls all cell activities, including reproduction.
- “Brain” of the cell.
Classroom analogy - teacher

12. Some chemical changes occur here.
CYTOPLASM
Holds all organelles.
Some chemical changes occur here.
General analogy - jello with fruit in it
