Mitosis Cell Lab
Life exists almost every where on this planet and if we are to attempt to comprehend what life is in all of its magnificence we must look at its simplest forms. Even a cell, the smallest form of life known is extremely complex. All life begins as a single cell. I can not begin to understand the depth of what it takes for one cell to multiply and change until we become conscious of ourselves. There are two types of cell division, Meiosis and Mitosis. Meiosis is where a cell splits and becomes four different cells. Mitosis is the process that allows a cell to split into two identical cells. This happens by having all of the DNA replicate before the cell splits so each has all of the original DNA. My lab shows mitosis in cell reproduction, because I do not have a microscope powerful enough to see the actual process within the nucleus I can not observe the chromosomes actually duplicate and separate. It is powerful enough to allow me to see cells splitting and I can observe the population growth without the aid of tools or instruments. First I began by starting the yeast culture in a bowl. I then removed a sample to observe it using a microscope. All throughout I measured t
The data set that I studied should resemble an exponential model but because of time constraints I only observed the very beginning of its growth. If I gave the population more time and I continued to add food it would probably have kept reproducing until constraints like space and/or its waste (alcohol and more) began to slow its growth. When I viewed the yeast under the microscope, the cells appeared average in size relative to the cells we looked for the other cell lab. I do not think I used enough iodine or I should have used a different die because I had a hard time seeing the nucleus. I did see the cells divide but it wasn't in great detail. I couldn't see the chromosomes but I did see the cell divide and blurry unknowns that was probably the nucleus and perhaps other organelles. When I looked at the sample on the lowest power I could easily see the population grow, even though individual cells could not be seen the sample seen never stopped moving. The main reason I conducted this lab was to show that mitosis is a process that in which cells reproduce. Personally I think that this is the most helpful lab we have done as of yet. The other labs were mainly about mathematics or rules. These concrete ideas are just as easily learned through lectures and work. But this lab deals with living things. In order to learn about concepts that can not be worked out on a calculator or memorized, a person must experience it. Unless we actually see these cell function occurring most people could not make the leap from a picture on a paper to what it actually must be like. Most of the problems I encountered were easily solved because I was at home, one that I couldn't solve is that I ran out of iodine after a few mess-ups and it may not have been the right dye to use anyway. When I put flour in the first time so it could survive, but longer the flour stopped me from seeing the cells on the slide. All I had to do was rinse out the bowl and try again, excluding flour.
