Mitosis and Meiosis

Name and Class Period: Read the summary of mitosis below and click on the blanks to choose the word that best fits in the sentence. Mitosis is a type of cellular reproduction where one cell splits and makes an identical copy of itself. In order to do this, it goes through several stages.The first one is prophase where the chromosomes become visible and are released from the nucleus.The next stage is called metaphase and this is where the chromosomes line up in the center of the cell.The chromosomes then move to the opposite sides of the cell in anaphase.Lastly, in telophase the nuclear membrane reforms around the chromosome and organelles are reproduced as the cell gets ready to split during cytokinesis. Once the cell splits, its spends the rest of its life in interphase, growing and doing its cell job and it will reproduce its DNA right before it gets ready to do mitosis again Keyword Sort Sort the keywords by dragging the term into the column for the type of cellular reproduction they identify. Mitosis goes through PMAT once used for growth, repair, regeneration and reproduction identical offspring creates 2 cells somatic cells cells created are diploid Meiosis gamete sperm egg variation in chromosomes crossing over occurs goes through PMAT twice creates 4 cells cells created are haploid Phases of Meiosis Label the pictures with the correct PHASE OF MEIOSIS.- Use I or II. NOT 1 or 2 (ex. anaphase I).Word Bank: Prophase I, Prophase II, Metaphase I, Metaphase II, Anaphase I, Anaphase II, Telophase I, Telophase II.**In the last blank, put the steps in order using the numbers.** Anaphase I Anaphase II Prophase I Metaphase I Metaphase II Telophase I Prophase II Telophase II 3, 4, 1, 6, 7, 5, 2, 8 Each gamete produced at the end of meiosis is identical true false Crossing over during meiosis explains why siblings look and act differently. true false Vocabulary gamete another name for an egg or sperm cell somatic cell another name for a body cell haploid a cell that contains half the number of chromosomes in a body cell of the organism diploid a cell that contains the full number of chromosomes for an organism chromatid one of the two strands of a duplicated chromosome gene a section of DNA that codes for a particular trait crossing over occurs when portions of homologous chromosomes are traded or switched during meiosis
