Cell Webquest

Cell Webquest:

On your journey will learn the importance of organelles and many other important structures of the cell. During this group investigation you will be given specific cell structures to research. In your research you should have a picture of the organelle and/or structure and briefly explain its function in the cell. The following organelles will be assigned:

Cell Wall            Cell  Membrane                                     

 Nucleus            Chromosomes/Chromatin         Mitochondria           Chloroplast

Golgi Body         Vacuole                 Rough Endoplasmic Reticulum    

 Smooth Endoplasmic Reticulum           Ribosome                     Cytoplasm

Cilia/Flagella                    Nuclear Membrane                           Lysosome 

Each student will be responsible for the notes that each student gives and will be tested on those notes. Secondly, each group will present their information to class via Powerpoint Presentation. Powerpoint Presentations are to be turned in to me no later than Monday @ 730am via email (brian.harrell@mnps.org). Each group will be graded on the following criteria:

Eating by Osmosis

http://www.astrobio.net/pressrelease/3224/eating-by-osmosis
What is osmosis and discuss tonicity? Then use contextual evidence to identify evidence that correlates with the title of the article. Begin Reading Section 7.2

Due Friday October 14,2011

http://www.sciencedaily.com/releases/2000/11/001120074801.htm: Find contextual Evidence that supports the statement as well as id the function of the Golgi APP and bolded words. Researchers at Yale have discovered that, contrary to previous beliefs, the Golgi apparatus is an organelle that exists independently of the endoplasmic reticulum and is a crucial component of cell division.

Excessive Protein intake

I would like for you all to summarize of the key points of this article using evidence from the article to support your points: http://www.fwhc.org/health/high-protein-diet.htm

Assignment for Bio 8/29/2011

Today in class we discussed 3 types of bonds: covalent, ionic, hydrogen bonding. The purpose of bonding is to create stability. Covalent bonding (polar is partial sharing and non polar in sharing of equal electrons). These bonds are strong and the more bonds the better. Hydrogen bonding is weak bond and example of that is water. The bonds are easily broken however Hydrogen bonding gives water a very unique property (partially negative toward Oxygen and partially positive towards Hydrogen). Ionic is when atoms actually lose electrons (sort of) forming a positive ion (atom) and negative ion (atom).
Secondly we discussed the properties of water: Such as density, specific heat, vaportization, good solvent, cohesion and adhension. Todays lab which we will be continuing on Wednesday will incorporate us solving for density of different liquids.

Understanding Free Radicals and Antioxidants

Respond to the following article: http://www.healthchecksystems.com/antioxid.htm
what am i looking for: Intro: what are free radicals and how are they formed, what is an antioxidant
secondly what are some effects of free radicals on the body. Furthermore what is the purpose of an antioxidant and how do they attact free radicals. Why is this article relevant to what we are studying at this moment: elements and compounds and why is your health important.
I will be looking for responses to this article to be detailed and specific. Use the article as a reference but fill free to look for other relevant sources of documentation. If you choose to use other documentation please site where the information comes from (If you plagerize and do not give credit you will receive a zero). I have my ways of checking. This is a Summative Grade which will count. Make it a good one.

Assignment 8/19/2011 Lab Safety Cartoon

The assignment for was to create a cartoon about lab safety highlighting one lab safety requirement. We also took a quiz over Lab Safety so ask about the Quiz when you return. Next week we will be beginning our unit on chemistry and biochem. Make sure you are present.
