Cytokinesis and Mitosis Reflection

Introduction: Find out the difference between Cytokinesis and Mitosis.  How do they go together in order to complete the cell division process?  


I did two virtual labs about Cytokinesis and Mitosis. We were looking for the cell divisions and also nuclear divisions. From the first virtual lab that I did I found out that there was a cellular division cycle and it was interesting that there was so many of them. There were 5 parts in the process. First is the Interphase. The Interphase has the most cells. The Interphase is the cell engaged in metabolic activity and performing its duty as part of a tissue. The chromosomes are not clear in the nucleus, although a dark spot called the nucleolus may be visible. Then comes the prophase. The chromatin in the nucleus begins to condense and becomes visible in the light microscope as chromosome. In this step the chromosomes begin moving. After Prophase comes the Metaphase. This is when the spindle fibers align the chromosomes along the middle of the cell nucleus. The line is called the Metaphase plate.The last to parts in the cycle are Anaphase and lastly Telophase. The Anaphase is when the paired chromosomes separate at the kinetochores and move to opposite sides if the cell. The Telophase is the last step in the cycle and it is when new membranes from around the daughter nuclei while the chromosomes disperse and are no  longer visible under the light microscope. In this virtual lab I also noticed that when the cell is not dividing, the nucleus always stays black, possibly being in the Interphase.

  1. This is a really good post. I like that you included images and an appropriate title. What did you find out about meiosis and mitosis?
