Laboratory #8 Mitosis and Meiosis 17 November 2010 Part1-Questions: a) Explain mitosis Mitosis is a process of asexual reproduction in eukaryotic cells. This process is divided into five stages: prophase‚ metaphase‚ anaphase‚ telophase and cytokinesis. A diploid cell duplicates its genetic information. Therefore the two diploid daughter cells will receive an exact copy of the genetic material. Explain meiosis Meiosis is a two round cell division process where a diploid cell divides into four

Cell division may happen by either mitosis or meiosis‚ depending on what type of cell is invovled. Mitosis is a process by which a cell divides to form two daughter cells. They each have the same exact number and kind of chromosomes as the parent cell. Meiosis occurs in the primary sex cells leading to the formation of viable egg and sperm cells. They reduce the number of chromosomes to half in each gamete so that when they are getting furtilized‚ the species chromosome number is kept even.

Mitosis and Meiosis When going over the cell cycle‚ mitosis and meiosis are two major components. Mitosis is the division of the cell’s nucleus‚ and is followed by cytokinesis. Cytokinesis is the division of cytoplasm. Mitosis is only one phase that a cell goes through in the cell cycle. Also the mitotic phase is one of the shortest phases. Mitosis can be broken down into five different stages; prophase‚ prometaphase‚ metaphase‚ anaphase‚ and telophase. In prophase the nucleoli starts to disappear

Abstract: The question of the investigation is if lectin can induce mitosis in the cell of an onion root tip. The hypothesis is that‚ if the lectin does not induce mitosis‚ then there should not be a great change in the number of cells that undergo mitosis. The alternate is‚ if the lectin does induce mitosis‚ then there should be an increase in of cells in mitosis. The control group of the experiment had root tip treated with water‚ and the experimental had root tip treated with lectin. Upon the

detail the Cell Cycle‚ Mitosis and Meiosis. Cells have the ability to grow‚ have particular functions‚ and replicate during their life. Although cell enlargement is part of organismal growth‚ cell replication is also required and allows growth without each cell becoming too large. All of these activities are part of a repeating set of events known as the cell cycle. The major feature in the cell cycle is cellular replication and what enables for cellular replication is the process of mitosis. Mitosis

AP Biology: Chapter 13 - Meiosis and Sexual Life Cycles Overview * The transmission of traits from one generation to the next is called inheritance‚ or heredity * Along with inherited similarity there is also variation * Genetics is the scientific study of heredity and hereditary variation I. 13.1 Offspring Acquire Genes from Parents By Inheriting Chromosomes A. Inheritance of Genes * Parents endow their offspring with coded information in the form of hereditary units

celled organisms grow by way of mitosis and the cytoplasmic division of body cells. On the other hand‚ meiosis occurs only in germ cells‚ which are put aside for the formation of gametes (sperm and egg). Reproduction by meiosis allows for species survival and it increases genetic variability. The process‚ during which the germ cells are generated is called meiosis. It represents nature’s solution to the problem of chromosome doubling that would occur‚ if two diploid cells‚ i.e. two cells with a
