Mainly composed of lipids & proteins
Lipid bi-layer & embedded proteins

Description: fluid like substance that fills the area of the cell outside the nucleus
Function: site of many cellular activities; surrounds organelles

7. 3.Nucleus
Function: control all activities of the cell (acts like a brain)

Free in the cytoplasm
Attached to other organelles.
Function: make proteins

11. Eukaryotic Cell Organelles and Function
Endoplasmic Reticulum (ER)
Nickname: “Roads”
Function: The internal delivery system of the cell (main transport system of the cell).

12. Endoplasmic Reticulum
2 Types:
Rough ER:
Rough appearance because it has ribosomes
Function: helps make proteins, that’s why it has ribosomes
Smooth ER:
NO ribosomes
Function: makes fats or lipids

14. Eukaryotic Cell Organelles and Function
Golgi body:
Function: packages, modifies, and transports materials to different location inside/outside of the cell
Appearance: stack of pancakes

15. ribosomes
Smooth ER
Rough ER
nucleus
cytoplasm
nucleolus
Golgi apparatus

16. 6.Lysosomes Description: small sacs of digestive enzymes
Function: breakdown macromolecules & digest old organelles (“clean up crew or janitors”)

Rough ER
nucleus
cytoplasm
nucleolus

19. AVID Thinking Strategy: Tattoo or Body Art
You are in charge of developing a tattoo to allow the world to know about one of the discussed organelles.
1. The centerpiece of the tattoo must be a slogan representing the organelle.
2. The surrounding artwork (minimum of 3 colors) must represent the organelle’s function
3. The artwork must be suitable for all ages and appropriate for viewing in all social situations.
complete sentence explanation of how the artwork represents the organelle AND the best location for the tattoo on the body

Converts energy to chemical energy
Only occur in plant cells
Contains own DNA
