Today, we finished our powerpoint presentation on the steps of mitosis for a fruit fly cell. Mitosis is the process in which a parent cell divides, or reproduces asexually to create two daughter cells or create a new cell. Some of the information that should be on your powerpoint is:
Phase 1 (Interphase): The chromatins in the nucleous replicate. The cell condenses. This one of the longest stages. Proteins are being produced.
Phase 2 (Prophase): The cell condenses. The chromatins turn into chromosomes. The nucleous begins to disappear. Centrosomes turn into centreols.
Phase 3 (Metaphase): The centreols make spindle fibers which attach to centromeres. The chromosomes line up. The nucleous is completely gone.
Phase 4 (Anaphase): The spindle fibers split the chromosomes. They pull to different ends of the cell.
Phase 5 (Telophase): The two nuclei form and the chromosomes unwind and turn back into chromatins.
Phase 6 ( Cytokinesis): When the cell splits into two daughter cells, there are now two nuclei. One in each cell. There is no more membrane binding the two cells together. They stay near eachother, but they are still two seperate cells.

Today, we started out by talking about chosing group leaders. One person a day in each table has to be the leader of the group meaning that they must keep their table group on task. The 3 responsibilities of the leader are:
1) Make sure everyone is engaged and everyone is participating in the discussions.
2)Make sure everyone is on task (members of the group are not wandering around the room, talking about non-science realted topics, making sure that if the group gets off topic that they get back on topic as quickly as possible)
3) Make sure things get done on time.
If the requirements are not met, the leader will lose their 5 participation points.

Next, we continued going over the questions that we did on 78 and 85 in the science book on March 1st.
4) Q:How does DNA compact before a eukaryotic cell divides?
A:The DNA is wrapped up around proteins in chromosomes.
5) Q:Why do injuries to the skin generally heal faster than injuries to the brain?
A:Because the skin cells have a shorter life cycle. It has more layers underneath that are available in case you lose cells when you get hurt and need more right away.
7)Q: What are the 2 main parts of the cell cycle?
A:The 2 main parts are interphase and mitosis.
9) Describe the steps of mitosis.
1) Prophase- chromosomes condense
2) Metaphase
3) Anaphase- chromosomes seperate
4) Telophase- 2 nucli are formed

Then, we started our lab. For our lab, we are using microscopes to look for tips of onion roots and then we answered questions on the worksheet we got.
