16. How does your body carry out so many functions?
Your body has organs (heart, lungs, kidney, etc) that do specific things so your whole body will function.
Cells have this too, but instead of organs, they are called organelles….
Organelles:
SMALL structures in the cytoplasm of eukaryotes that perform important functions

17. Organelles in ALL Eukaryote Cells:
Nucleus
Cytoplasm
Cell membrane
Ribosome
Endoplasmic Reticulum
Golgi apparatus
Mitochondria

18. Plant and Animal cells contain KEY DIFFERENT organelles to carry out their different functions
Plant Cell VS
Animal Cell

19. Different kinds of animal cells
white blood cell
red blood cell
cheek cells
sperm
nerve cell
muscle cell
Amoeba
Paramecium

20. Gallery Walk: 30 minutes
There are 10 stations AROUND the room. You and your group members will have 3 MINUTES at EACH station
In these 3 minutes you MUST:
DRAW a simple SKETCH of the organelle
WRITE the FUNCTION of the organelle
CREATE an ANALOGY for the organelle
Write if it is in a plant cell or animal cell or BOTH

21. What do I mean by analogy?
An analogy is a comparison between two things.
FOR EXAMPLE: The Cell is like a big CITY:
The nucleus controls the cell, so it is like the town hall
You and your group members must create your own cell city analogies for each organelle.
In the factory you have workers and certain physical conditions that each play a part to make the factory work. SIMILARLY, the cells have individual strctures that make it work.

22. Cell Membrane FUNCTION:
thin, flexible layer that surrounds the cell’s cytoplasm that controls what goes into and out of the cell and protects it from outside environment

A system of folded tube-like structures attached to the nucleus that transport materials around the cell
Rough ER: has ribosomes
Smooth ER: no ribosomes
Location: BOTH PLANTS AND ANIMALS
As a CITY: roads

28. Endoplasmic Reticulum (ER):

29. Golgi Apparatus Function:
Packages proteins for shipment around the cell
