Review
Our first topic is…
Photosynthesis and cellular respiration!!!

Review
Our second topic is…
Phases of mitosis and meiosis!!!
![Page 8: Review for Unit Test](https://reader036.vdocuments.mx/reader036/viewer/2022062423/5681463f550346895db34948/html5/thumbnails/8.jpg)

Cell Phases – Mitosis
Interphase: Time in between cell divisions.At end of interphase,
chromosomes double.
Prophase:
Sister chromatids (the duplicated chromosomes) attach to one another.
Metaphase:
Sister chromatids line up in the center of cell (called the metaphase plate)
Time in between cell divisions. Telophase:
Anaphase:
Spindles pull sister chromatids apart, to opposite ends of the cell.
Cleavage furrow forms, “pinching” cell in half
Interphase:

Cell Phases – Meiosis
Meiosis has two parts Meiosis 1: genetic information switched,
cells divide Meiosis 2: cells divide ONE MORE TIME
![Page 11: Review for Unit Test](https://reader036.vdocuments.mx/reader036/viewer/2022062423/5681463f550346895db34948/html5/thumbnails/11.jpg)
Choices
Your classwork grade today is based on you completing one of the following:1. A foldable about mitosis, meiosis, or
their differences2. A poem/rap song about the phases of
mitosis
3. 8 possible test questions (with answers!) that you will present to the class

Review
Our third topic is…
Products of mitosis and meiosis!!!
![Page 13: Review for Unit Test](https://reader036.vdocuments.mx/reader036/viewer/2022062423/5681463f550346895db34948/html5/thumbnails/13.jpg)
Mitosis
Mitosis goes through PMAT one time. Therefore, it produces two cells. Each of these cells is exactly the same.
Since all somatic cells are 2N, and the cells produced by mitosis are exactly the same as the original cell, the cells produced by mitosis are 2N.
![Page 14: Review for Unit Test](https://reader036.vdocuments.mx/reader036/viewer/2022062423/5681463f550346895db34948/html5/thumbnails/14.jpg)
Meiosis
Meiosis goes through PMAT two times. Therefore, it produces four cells. Each of these cells is different.
Each gamete is different because in meiosis 1 some genetic information gets switched between chromosomes. This is why you do not look exactly like your relatives.
Each gamete has half as much DNA as the original germ cell. So, each cell is only 1N.

Ms. Stroh’s very nice
She expects us to work hard
LY’s a bully

And a final message from Ms. Stroh’s class…

Review Packet
If you completed half of the review packet last night… Good work! You get an answer key! Check your answers, and ask me questions.
If you did not complete half of the review packet last night… You can work on it now, and ask me
questions. No answer key, sorry. Do your work next
time.
