2. Announcements Period E/G: Homework due tomorrow
Organelle Quiz on Friday

3. Organelle Wrap up

4. Nucleus Control center for cell Nucleolus makes ribosomes
Function
Control center for cell
Nucleolus makes ribosomes
Characteristics
Contains genetic material (chromatin)
Surrounded by membrane barrier
Location
Usually the center of the cell, in the cytoplasm
Means center, most important part
Students should label the central light part as the nucleus as well as the membrane barrier

5. Nucleus Color & Label your Cell! Nucleolus – Purple
Nuclear envelope
Nuclear pores
Chromatin
Color & Label your Cell!
Nucleolus – Purple
Nuclear envelope – Light Blue
Chromatin - Yellow

6. Ribosomes Function Where protein synthesis takes place Characteristics
Small particles of RNA and protein
Is made in the nucleolus
Location
Free floating in the cytoplasm or attached to the endoplasmic reticulum

7. Cytoplasm Function Holds the organelles in place Characteristics
Jelly like substance in which all organelles reside
Location
Inside cell but outside of nucleus
Color and Label Cytoplasm Pink

8. Endoplasmic reticulum
Function
Where lipids and proteins are assembled
Rough ER where ribosomes are attached and proteins are assembled
Smooth ER is where lipids are assembled
Characteristics
Folded internal membrane
Two parts:
Rough ER appears bumpy where ribosomes are attached
Smooth ER appears flat and flat and even
Location
Associated with nucleus, but may be spread throughout cell

9. Endoplasmic Reticulum
Label and Color Rough ER Dark purple (violet)
Label and Color Smooth ER Light Green
Rough ER
Smooth ER

10. Golgi Apparatus Function Characteristics Location
Modify, sort and package proteins from ER
Exports proteins to membrane or lysosomes
Characteristics
Stack of tightly packed membranes (like a stack of pancakes
Location
Close to the ER

11. Endoplasmic Reticulum and Golgi Apparatus
Label and Color Rough ER Dark purple (violet)
Label and Color Smooth ER Light Green
Label and Color Golgi Apparatus Red
Golgi Apparatus

12. Mitochondria Function Characteristics Location
Converts chemical energy into usable forms through respiration
Characteristics
Has an inner and outer membrane
Inherited from mother
Has its own DNA
Location
Floating free throughout the cell
Color the Mitochondrion orange.
Mitochondrion

13. Chloroplast (PLANTS ONLY!)
Function
Converts sun energy to chemical energy through photosynthesis
Characteristics
Has an inner and outer membrane
Contains green pigment – chlorophyll
Has its own DNA
Location
Floating free throughout the cell
Color the Chloroplast dark green.
Chloroplast

14. Lysosome Function Characteristics Location
Breakdown of macromolecules (“digestion”)
Removes “junk” from cell
Characteristics
Contains digestive enzymes
Location
Free floating in cytoplasm

15. Vacuole Function Characteristics Location
Stores material
More prominent in plants
Provides structure for plants
Characteristics
No distinct shape
Very large in plants
Location
Free floating in cytoplasm
Color Vacuole gray (pencil lead)
Vacuole

16. What’s left? Cell Membrane Cell Wall Semipermeable barrier
Maintains structure and rigidity for plant cells and prokaryotic cells.

17. Cytoskeleton Supporting structure Maintains shape
Section 7-2
Supporting structure
Maintains shape
Assists in movement of cell
Cell membrane
Endoplasmic

21. Cell Model Project Create a model of a cell Can be 2-D or a 3-D model
CANNOT be a colored diagram of a cell
Be creative
use food, household materials to make different organelles!
Choose a plant or animal cell to create (fill in on your instruction form).

22. Cell Model Project Rubric Creativity Labelling Organelle
Organelle Function
Organelle Identification
