Lab Report #1 Ahmad Dweik Question/Problem Which phase of cell division / mitosis is seen most often in whitefish blastula? Introduction Cell division is the process of a parent cell dividing into two daughter cells. Mitosis is a type of cell division. In mitosis a parent cells chromosomes are copied and separated into two cells with different nucleuses but same DNA. There are steps or phases that take place that make the cell divide. The first phase is called Interphase. In interphase

Describe the normal process of cell division (mitosis)‚ and explain how this process is affected in the abnormal growth of tumours Cell division is important as it allows cells to reproduce also they divide so that organs can grow and be repaired. “In the form of cell division called Mitosis‚ one cell divides into two daughter cells‚ each of them then complete but smaller than the original cell.” [1] The cell cycle is a seven stage process by which a cell duplicates itself and divides in two.

Mitosis is a process of cell duplication‚ or reproduction‚ where one during this process gives growth to two identical daughter cells; however‚ there is no crossing over. Mitosis is asexual and has 1 division of the nucleus in cytokinesis (Simon‚ Reece‚ & Dickey‚ 2010). Meiosis is the splitting up of germ cells‚ with each possessing half the number of & Dickey‚ 2010). Meiosis is sexual and has 2 nuclear and cytoplasmic divisions. However‚ one must remember they both are preceded by Interphase

The Phases Of Mitosis Mitosis is when the cell divides into 2 identical cells. It has 4 phases- prophase‚ metaphase‚ anaphase and telophase. The stage before these 4 phases is the interphase‚ when a cell has not yet started dividing. In this experiment‚ I used the root tips of onion where is the place of growth and is active in cell division‚ to identify the number of cells in each stage of division including interphase‚ and determine the relative duration of the phases of mitosis. Result:

Cell Cycle Lab (Onion Root Tip) 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). You will be submitting a lab report as

for educational purposes it can also be used in cancer tumor diagnosis. For example‚ a person who does not have cancer will not have as many cells undergoing mitosis compared to the amount of cells that are in interphase. However if a person with cancer is examined‚ results will show that there are more cells that are going through mitosis compared to the cells that are in interphase. This is because cancer cells grow repeatedly and more frequently than normal cells. This lab has two limitations

Compound Microscope Parts A high power or compound microscope achieves higher levels of magnification than a stereo or low power microscope. It is used to view smaller specimens such as cell structures which cannot be seen at lower levels of magnification. Essentially‚ a compound microscope consists of structural and optical components. However‚ within these two basic systems‚ there are some essential components that every microscopist should know and understand. These key microscope parts are illustrated

occurs 10. Compare the number and type of cells that result from meiosis vs mitosis. Mitosis 2 diploid cells‚ that are somatic cell (cells that are not gametes) and identical to each other and to the parent cell Meiosis makes 4 haploid cells that are gametes and are all different from each other and from the parent cell 11. How do the genetic contents of cells resulting from mitosis and meiosis differ? Mitosis are identical‚ while meiosis is not identical 12 If a diploid cell containing
