Cell Division - 9/16
Summary: Cells growing and dividing is known as cell division or mitosis. There are few steps to this process, the steps are interphase, prophase, metaphase, anaphase, telophase and cytokinesis. Interphase is the processes were cells grow, copy their DNA, and prepare for division. Prophase is were the cell's chromatin condenses and turns into chromosomes. Metaphase is the step were the chromosomes line up across the center of the cell. When anaphase occurs, the centromeres split and the chromatids separate. During telophase a nuclear cover forms around the chromosomes. At the final step, cytokenisis, the cytoplasm splits moving organelles into the new cell. The DNA is copied before mitosis occurs to insure the new cell has the correct genetic information.
S&EP 4: I used a flip book to to display and analyze data. We drew the steps of mitosis slowly changing. This helped with the understanding of mitosis as you can see the small changes the cell makes in it's development of turning into two cells. Also I recognized patterns in data and saw relationships between variables. For example, I observed that the centromeres in most steps was either moved do a different spot or looked different, but I knew it was always there.
XCC: Stability and Change: The cell goes through a special change in it's lifespan, mitosis. The cell is contentiously changing until it splits and becomes two cells. First it must copy it's DNA so the daughter cell has the correct genetic information, then it goes through interphase, prophase, metaphase, anaphase, telophase and cytokinesis. Depending on the animal/plant the cell is in the cell cycle can take from 100 minuets to 24 hours to complete.
Multiplier: This week I was a creator as I had to make my own flip book and I had to be confident in my self of what I was putting down on the the flip book was correct.
