Mitosis Lab Links

For today's lab you need to complete the following four activities:

Activity 1:  Please click here for the website for the Cell Cycle and Mitosis Computer Activity

Activity 2: Please click here for the website for Karyotyping Abnormalities Activity

Activity 3: Please click here for the website for cancer and the cell cycle

Cell Cycle and Mitosis

Cell Cycle and Mitosis ~ 3.25 minutes (Highly recommend watching!)

Cell Cycle Checkpoints ~ 3.75 minutes (Highly recommend watching!)

I would highly recommend going to this website and looking at the animations for the cell cycle:
The website is called "Cells Are Alive." Click here to view the website.

Cell Cycle Intro ~ 5.5 minutes (can skip to 2:23 but the beginning is interesting to watch)

Chromosomes

What is a chromosome? ~ 3 minutes

Bill Nye - Genes and Chromosomes ~ 1 minute

Look ahead ~ 2.5  minutes


Diploid vs. Haploid Cells ~2 minutes

Somatic Cells ~ 1.5 minutes

Unit 3 Review

Self Assessment #5 Key 

Self Assessment #6 Key

Cellular Respiration

Overview of cellular respiration with oxygen~ 4.5 minutes   (would recommend watching)

Stage 1: Glycolysis **~ 1.5 minutes

Stage 2:

           With Oxygen : Formation of Acetyl- CoA and Krebs Cycle **~ 2 minutes
                                    Electron Transport Chain **~ 2 minutes

           With Out Oxygen: Fermentation 2  ~ little over 2 minutes
                                          Fermentation 3 ~3.5 minutes
                            (You do not have to watch all 3 I would suggest watching at least one)


** The videos are put on to help you understand the process better. You do NOT need to know any additional terms. Just the big idea and the products and reactants.

Why Leaves Change Color:
Leaves color because of the change in temperature and the amount of light available to the trees. As fall comes we get less hours of sunlight throughout the day. When there is less sunlight, the energy needed to produce chlorophyll (the primary pigment or light collector) is greater then the energy chlorophyll is producing. Therefore chlorophyll becomes inefficient and the plant stops making chlorophyll. When we no longer have a large amount of chlorophyll in the leaves the other pigments will be displayed in the leaves.

To learn more you can watch the following videos:

Why do leaves change color?  Gives some background + answer. WOULD RECOMMEND (3 minutes)

Different Pigments   (3 and a half minutes)

What weather conditions produce, which leave colors (1.5 minutes)
