This is a colored onion plant under a microscope and you can see the different stages of mitosis. We did this in class to try and identify prophase, metaphase anaphase, and telophase. The fourth cell on the top row is in prophase because it's growing. On the bottom right that cell is in metaphase because you can see the sister chromatids lining up in the middle. The fifth cell on the third row is in anaphase because the sister chromatids just separated and are being pulled away from each other. The second cell on the third row is in telophase because you can see the plate that formed down the middle to separate the cell.

Unit Summary
In this unit we learned about the cell cycle, mitosis, and meiosis. First we learned about the cell cycle which is the cycle that the cell divides to form 2 cells. The first stage of the cell cycle is called G1 and the cell begins to grow, the organells increase in number, and most of the time is spent in this stage. Next the cell goes through the S phase which the DNA is copied and the cell now contains 2 sets of identical DNA. The last phase is G2 and the cell grows some more and the cell gets everything is order before M phase.
Next we learned about M phase or Mitosis which creates two daughter cells. First prophase takes place and the sister chromatids tightly coil up, the nucleus starts to break down and fragment, and the spindle starts to form. Next Metaphase occurs and the sister chromatids line up together ,in the middle, on the spindle. Then, anaphase is when the sister chromatids pull apart because the spindle starts to shorten. Lastly Telophase takes place and the nuclear envelope forms creating two new nucleuses around the daughter chromosomes.
Lastly we learned about meiosis which is like mitosis but it happens twice to form four daughter cells. Meiosis produces somatic (body) cells and gametes (sex) cells and meiosis occurs so gametes cells only have twenty three chromosomes instead of forty six chromosomes. Somatic cells are diploid cells and gametes are haploid cells. Lastly meiosis uses homologous chromosomes which are genes that are similar but not identical. During meiosis1 the homologous chromosomes seperate and two haploid cells are produced. Next meiosos1 occurs and the sister chromatids seperate and four haploid cells are produced.
What I liked most in this unit is learning about the gametes because it involved the chromosomes and the genes. What I would like to learn more about is the cell cycle because I feel that we only briefly went over it and I would like to go in greater detail.
