Week 17 Mitosis and Meiosis


Cell Division and Differentiation
Monday Nov 28
QFD: Not what we say about our blessings, but how we use them, is the true measure of our thanksgiving.” ― W.T. Purkiser
THis week’s learning objective : HS – LS 1-4 Use a model to illustrate the role of cellular division (mitosis) and differentiation in producing and maintaining complex organisms.
Today’s performance objective : Students will know and be able to explain how a cell differentiates cell division by the processes of mitosis and meiosis by:, investigating the processes, answering questions and creating a sequence concept map that explains both processes
Essential question : Describe the differences between mitosis and meiosis as they relate to cell differentiation

Cell Division and Differentiation

Make a special section in your notebook titled “Cell Division”
record answers to the following questions into your notebook :
look them up on the Internet
1. In your journal, draw a chromosome and indicate the location of a gene on the chromosome.
2. Skin cells are constantly being shed. How does your body replace these lost cells?
3.  How are genes passed on from the cell of a father to his son?
4. How are many specialized cells in the human body generated from one fertilized egg?

Part 2
Sequence map – place the cards in the correct order that you think occurs within the cell and create a sequence concept map to represent your discovery for both mitosis and meiosis

Part 3 write. Reflection that describes at least 3 differences between the two processes
Hw:

, define the following words
Vocabulary:
• mitosis
• meiosis
• gonad
• gene
• chromosome
• chromatid
• centromere
• centriole
• nuclear membrane
• cytokinesis
• replication
• stem cell
• pluripotential cells
• totipotential cells
• cell differentiation
• embryo
• cell
• tissue

QFD: As we express our gratitude, we must never forget that the highest appreciation is not to utter words, but to live by them. ~John Fitzgerald Kennedy
THis week’s learning objective : HS – LS 1-4 Use a model to illustrate the role of cellular division (mitosis) and differentiation in producing and maintaining complex organisms.
Today’s performance objective : Students will create a concept map for mitosis and meiosis, and will take Cornell notes on the main ideas of cell division
Essential question : Hypothesize which obstacles a cell must overcome in order to produce another cell.



concept maps created on paper and places around room
Film clips on mitosis and mitosis ( Cornell notes)
A multicellular organism that is diploid (2n) develops gametes (egg or sperm cells) that are haploid (n).
Fertilization occurs when an egg and a sperm cell (n + n) join to produce a zygote (2n).
The cells of the zygote divide through the process of mitosis and they differentiate to form various parts of the body. Mitosis continues to promote growth and development.
A multicellular organism is produced that is diploid (2n).
Cornell notes
Sequence map created by students for both meiosis and mitosis

Hw: use 10 of the vocabulary words to describe mitosis , then draw a simple picture that represents your paragraph
Wednesday Nov 30
QFD: Thanksgiving dinners take eighteen hours to prepare. They are consumed in twelve minutes. Half-times take twelve minutes. This is not coincidence. ~Erma Bombeck
THis week’s learning objective : HS – LS 1-4 Use a model to illustrate the role of cellular division (mitosis) and differentiation in producing and maintaining complex organisms.
Today’s performance objective :
Essential question : Make a list of types of cells in the body (muscles, digestive, etc) and what
organelles or features might be especially important for each type (nucleus, etc)
Part 1 20 min
Write down 3 similarities and differences in the processes of mitosis and meiosis.
Write down 3 similarities and differences in the results of mitosis and meiosis.
Compare answers with your neighbors ,fours
Part 2 model building pairs
Construct a model of mitosis and one of meiosis in an organism with a diploid number (2n) of four chromosomes.
use the materials provided in class to make your model 20 min
draw a diagram of your model on the paper provided in class
Part 3 reflection write a reflection of two things you learned today about today’s objective

QFD: Forever on Thanksgiving Day The heart will find the pathway home. ~Wilbur D. Nesbit
THis week’s learning objective : HS – LS 1-4 Use a model to illustrate the role of cellular division (mitosis) and differentiation in producing and maintaining complex organisms.
Today’s performance objective:
Essential question : Compare and contrast mitosis and meiosis
1) Lab – mitosis and meiosis on the table

Friday dec 2
QFD: I like football. I find its an exciting strategic game. Its a great way to avoid conversation with your family at Thanksgiving.” ― Craig Ferguson
THis week’s learning objective : HS – LS 1-4 Use a model to illustrate the role of cellular division (mitosis) and differentiation in producing and maintaining complex organisms.
Today’s performance objective : Students will know ad be able to describe cellular respiration and photosynthesis by completing the biome project
Essential question : How are the processes of photosynthesis and cellular respiration interrelated?
1)quiz mitosis meiosis

Cell types and specializations:
• White blood cells: lysosomes;
• Muscle cells: mitochondria;
• Skin cells: flat sheets, melanin pigment;
• Red blood cells: no nucleus, full of hemoglobin protein;
• Nerve cells: cell extensions (axons), rough endoplasmic reticulum;
• Intestinal lining cells: microvilli for absorption, tight junctions between cells;
• Gland cells: secretory granules, rough endoplasmic reticulum, hormone receptors;
• Sensory receptor cells: stereocilia, chemical receptors.
Hw: honors Research current articles about cancer that focus on cell signals for mitosis to start or stop. What is different in cancer cells that causes them to undergo continuous mitosis?
