Understanding the differences and similarities between Mitosis and Meiosis is a challenge!  This video might help.  http://www.diffen.com/difference/Meiosis_vs_Mitosis

The presenter is definitely an evolutionist and his worldview is definitely not Christian, but when he sticks to the facts, his information is definitely helpful.

Once again, the intricacies of this one process — reproduction — point to an amazing Creator.

Rather than performing Experiment 7.1 in class, I would like you to watch the following You-Tube video:

http://www.youtube.com/watch?v=jvoevXwujlQ

Then for Experiment 7.2 please do the following:

1.  To view animal cells undergoing mitosis, visit http://www.enchantedlearning.com/subjects/animals/cell/mitosis/label/label.GIF

2.  Sketch (or print) the cells as shown.

3.  Label each cell with the stage it is in.

4.  Check your animal cell labels here:  http://www.enchantedlearning.com/subjects/animals/cell/mitosis/label/labelanswers.GIF

5.  Click on this link to see the differences between plant and animal telophase and cytokinesis.  Write a paragraph describing what happens in each type of cell.

Please bring your labeled drawing and paragraph to class on January 11.

These pages can be attached to your test for Module 6 for extra credit.  Each page (you must do the coloring) is worth 2 points.

Here are some photos of the incredible edible cells that the CACHE Biology class of 2013-2014 created.  Notice the different bases:  cake, jello, pizza crust.  Also there are two ways of labeling the organelles:  either a key or individual labels.

After observing your bread mold samples, sketch the following diagram and add it to your notes:

This image is from a Bread Mold Experiment page.  You will also find some interesting photographs there.

After looking at the specimens from Experiment 4.1, please sketch and label the diagram at the top of this page from Backyard Nature:  Club Fungi Diagram

After observing the growth of baker’s yeast in class, sketch the following diagrams and add to your lab notes.  You do not have to include the Chinese characters!  These diagrams are taken from the Angel Yeast Company website which has some interesting information on the history of yeast.

For experiments 3.2 & 3.3, you will need to view drawings  & photographs of organisms in Kingdom Protista.

These diagrams have coloring directions to help identify different parts of the organisms.  You may choose to draw the cell (including organelles, cilia, plasma membranes, etc.) OR you may print off the page and color and label the picture.

Include your name, the date, sub-kingdom and phylum on each page. Below you will find links to the pages and the copy that I colored.

Paramecium:

Paramecium Coloring Page

Amoeba Coloring Page  

Euglena Coloring Page

Volvox Coloring Page

Spirogyra Coloring Page 

This will download to your computer for printing.

Diatoms Coloring Page

This site has several pages.  You will only need to print the first one.

Since you have drawn and/or colored a sample of each organism, you should be able to identify some of the parts of each cell that you see at the Museum.

Begin by viewing the Freshwater Collection.  You will want to visit Protist Parade to see Amoeba, Volvox and Euglena.  In the Ciliate Centre you will find Paramecium.  Also pop into the Diatom Depot & Algae Archive.

In the Marine Exhibit you will find additional Diatoms and Algae.

Please spend some time exploring the museum and note at least one interesting fact on each of your drawings.

Today while I was hunting for some videos to supplement Module 8, I came across hundreds of pieces from Bozeman Science on You-Tube.  Paul Andersen covered several topics from our current study on Mendelian Genetics, but I also found demonstrations on other biology subjects, chemistry and physics.  So if you are stuck on a particular unit, search “Bozeman Science Paul Andersen” on You-Tube and you may find just the additional explanation that you need.

Please be aware that Mr. Andersen is very pro-evolution.
