Honors Biology_Monday Sept. 12 Class

Good Morning H.Biology!!

You will be working on the cellular organelles webquest today during class.  The substitute will provide a hard copy of the webquest to you.  If you are having difficulty accessing the websites on the webquest, then use the links below:

Link #1 (For animal and plant cell information): http://www.cellsalive.com/cells/cell_model_js.htm

Link #2 (For Prokaryotic cells information): http://www.cellsalive.com/cells/bactcell_js.htm\




Cellular Organelles Project for Block #1:
You will be working in groups of 4 to complete the cellular organelles project.  This project will include: I) a mini poster presentation on your assigned organelle along with II) a whole cell 3D model.  Due date is Monday September 19, 2016

I) The mini poster presentation will include the following information:
a. Function of organelle
b. Structure of organelle
c. Explanation of how the structure of the organelle helps the organelle perform its job
d. Which other organelles work directly with your assigned organelle? Explain how your organelle must work in collaboration with other organelles in the cell in order to keep the cell alive and functioning.
e. Explain what could go wrong if your organelle fails to do its job.  What diseases could result if your organelle cannot perform its function.  Please do not say, "the cell will die and then the human will die."  You must provide specific details on how your organelle is important in the life of a single cell, and how the failure of your organelle to do its job can lead to human disease.

Details can also be found here.

II) Model: 
In Science models are used to make complex ideas easier to understand.  To demonstrate your knowledge of plant and animal cells you are to construct a model that adheres to the following guidelines.

1.     Choose to make a plant or animal cell. 

The cell must include the following structures :
a.     Plant Cell: nucleus, chloroplast, central vacuole, cell wall,  cell membrane, rough endoplasmic reticulum, Golgi Apparatus, ribosomes, mitochondria

b.     Animal Cell: nucleus, cell membrane, rough endoplasmic reticulum, Golgi Apparatus, mitochondria, vacuole, lysosomes, ribosomes


3. You can make the 3D model out of the materials such as play doh, pipe cleaners, beans, and construction paper.  You should keep in mind that a cell is three dimensional, and that model must reflect that concept.


4.    Your cell model should be as accurate as possible. The cell parts should be located where they belong. For example: the nucleus should be bigger than ribosome’s, the chloroplast should be green, a plant cell must be rectangular or your animal cell must be circular.

5.    The cell must be identified as plant or animal.  Each organelle must be fully labeled with its name and function (accurate description of its role in the cell) either on the model, OR numbered on the model and identified using a separate key containing each organelle’s full name and function.  

III) Organelle Assignment for Block 1
You will be working in groups of 4, which will be the same classmates at your table group.

Riley's Table - Nucleus
Ahmad's Table - Ribosomes
Sophia's Table - Mitochondria
Caroline's Table - Rough Endoplasmic Reticulum
Hannah's Table - Chloroplast
