Meiosis BIOL 1111 Introduction Meiosis is the second important kind of nuclear division. It resembles mitosis in many ways but the consequences of meiotic divisions are very different from those of mitotic divisions. While mitotic division may occur in almost any living cell of an organism‚ meiosis occurs only in special cells. In animals‚ meiosis is restricted to cells that form gametes (eggs and sperm). Each species has a characteristic number of chromosomes per somatic cell. Fruit flies

illumination and improve microscopic image outcome. The aim was the study was multi fold; generating microscopic specimen of CHO cells in which we used observed with different microscopic visualization techniques as well as the different stages of mitosis. Then after we examined the crucial relationship between structure and function. Finally‚ the most efficient way of cleaning your hands and prevent bacterial growth‚ using was analyzed. The CHO cell samples were fixed; one with formaldehyde

is because our numbers of the number of cells in each phase of mitosis are similar to the rest of the groups‚ so we can assume our results are most likely correct. We can also assume our calculations are right because we know that Interphase is the most active phase in the process of cell divison‚ which would agree with our calculations since we assume that approxiamtly 93% of cells are going though Interphase. The phases of mitosis are much shorter then that of Interphase‚ and the cell spends less

magnification was not high enough. However‚ many nuclei were visible indicating that the cell were in interphase or early prophase. The majority of cells were in interphase‚ as seen in the graph and charts above‚ while the rest were in other phases. Conclusion and Evaluation: As expected‚ the results from the Mitotic Index Lab show that most cells were in interphase meanwhile there were not many cells in the other four phases. This goes to show that this stage is relatively long while the other ones

WHAT IS A CELL? It is the smallest unit of life that is classified as a living thing‚ and is often called the building block of life. The cell is the basic structural and functional unit of all known living organisms. Some organisms are unicellular (made of only one cell) while others are multicellular (made up of several cells). The word cell comes from the Latin cellula‚ meaning‚ a small room. The term was coined by Robert Hooke in a book he published in 1665 when he compared the cork cells he

division. They are binary fission‚ mitosis‚ and meiosis. When cell division is in the form of mitosis it is usually associated with cell growth‚ replacement‚ and repair. When the cell goes through meisosis it usually involves asexual reproduction. Both the process of mitosis and meiosis involve the duplication of the DNA and the splitting of the nucleus. Mitosis is a type of cell division that produces two genteically identical cells from a single cell. Mitosis is basically a process that cells
