Week 16 Mitosis and Meosis


Cell Division and Differentiation
Monday Nov 16
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: Honors, define the following words

• mitosis
• meiosis
• gonad

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: define the terms from Monday on this site
Honors : Hw: use 10 of the vocabulary words to describe mitosis , then draw a simple picture that represents your paragraph
Wednesday Nov 18
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 Nov 18
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) finish biome project powerpoint (google classroom)

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?

  1. hey Borden what do we about the claim evidence and reasoning for the biome guidelines?

  2. Claim refers to a hypothesis : what did you plan to accomplish w this lab , evidence refers to what actually happened , and reasoning is why do you think your results turned out the way they did … Be specific on all parts .

  3. Hello Mr. Borden I had a question on the dihybrid worksheet problem C. How could the dwarf plant be heterozygous if it’s a recessive trait. Thank you.

    • Dwarf would have to be the dominant trait for that to occur ! , you did a great job on your test btw 🙂

      • Thank you Mr. Borden! So, it would be rr?

  4. Unless it specifically said dwarf is dominant yes it must be recessive rr

  5. Hello Mr. Borden, I was doing the corn snake genetics homework and I was a little confused. What do the blank spaces above the nickname of the snake mean? Do i just fill it out with the corresponding allele? Also, I was confused on number 5 and 6 and how to find the genotypes. Thank you

    • Sorry to respond so late .. The top should be left alone , as for 5 and 6 the directions do indicate the type of cross required, see me in morning from 730 by 600 building before school if you require more assistance
