Hypothesis

After researching, I predicted that I would see different numbers of cells (which are the bubbles or the circles in all the different stages). I got some pictures from a website and I knew what to do, and how to tell how many cells are in each stage after staining the onion root tip.

Procedure
I did this project all on my own. I had to wait one day to get the microscope, I then got the onion root tip and sliced it into small pieces. I stained the root with red food coloring to make it more visible, and then placed it between two glass slides to make it clear. I then waited for the cycle to finish. It took me about 25-35 minutes to finish the whole cycle including preparing and cleaning up. I then recorded my data in a table that explains all the numbers of cells I found in all different stages.

Conclusion

This project was lot of fun! It was my first time using a microscope by myself, and I loved looking at the cells and counting them during their different stages. After I had waited for all the stages, I recorded the number of cells found. I did my experiment on two different pieces of onions. The time between both were not similar, because there indeed was a difference between all of them. I saw the nucleus and all the cells moving and transforming between the stages. I really did understand the processes more than when I had read

In this virtual lab activity, you will be observing the cell cycle in the tip of an onion root. The root tip is responsible for the downward growth of the root and is one of the regions in the plant where cells are actively dividing and growing. Because of this, the root tip is an excellent system in which to observe the entire cell cycle, including the processes of nuclear division (mitosis) and cell division (cytokinesis). Puppies increase in size as their cells grow and divide. Almost all cells complete a full cell cycle that includes interphase and cell division. In interphase, cells serve their specialized functions, grow, and copy their genetic material. Mitosis is the first stage of cell division, in which the copied chromosomes are separated into two new nuclei. Then in cytokinesis the cell divides into two daughter cells. If no mutations or errors occur, the genetic material in each daughter cell is identical to what was in the original cell.…
