Can someone read over this experiment for biology and tell me if it makes
for this experiment with both slides they were viewed at 400x total magnification with a slightly zoomed in on the coarse adjustment (however i totally forgot to write these down.) the onion root looked slightly like a brick wall with tiny dots inside of it (the nuclei). the cell walls were not clear however the nuclei was very
prophase: the chromosomes are condence and become visable for the very first time during this cycle. the fibers begin to form and the membrane begins to disintegrate.
metaphase: the fibers attach to the center of each sisters chromosomes. they then align in the center of the cell. the nuclear membrane disingrates completely.
anaphase: the center begins to split and the sister chromosomes then migrate towards the other sides of the cell.
telophase: the chromosomes are now clustered on both ends of the cell. the membrane is now reforming itself. the cell plate begins to form between both daughter nuclei. this is then followed by something called cytokinesis.
i now changed my slides to the whitefish blastula.
viewing at a 400x magnification the cell shape stayed pretty much similar and they still had a circle like shape to them. in one certain cell, the chromosomes that had lined up in the previous stage, had broken apart from their duplicates and had headed into a different centriole. the stage the cell is now in is the anaphase. when observing the whitefish for the stage of telophase, the shape stayed the same as well except for one cell which is currently in the telophase stage. the cell that is in the different stage looked like two different circle cells that joined one another. this stage the chromosomes reached the center and a nuclear membrane than began to form around each nuclei.
30% of the cells are in the prophase stage
5% of the cells are in the metaphase stage
5% of the cells are in the anaphase stage
5% of the cells are in the telophase stage
35% of the cells are in a stage of mitosis
in this conclusion i see that the hypothesis is right. it states that cells will go thru multiple stages of mitosis in their lifetime and they surely do! it also states that we (the viewer) would be able to see the different slides in one stage of mitosis. we were able to see this as well. the other thing i would like to state is that the slides used for the microscope were not large or very clear, but it was good enough to sort of have the idea of what is going on. i have learned that both of the slides are continuously reproducing and creating new and different cells and i was able to learn how to calculate the percentage of cells in the different stages.. i was able to learn a lot from this experiment and i was also able to learn more about a microscope then what i already knew. if i could change this experiment i really would not in any way. it was simple and fun to learn about the different cells and the different ways that they move and the ways they reproduce.
