clwhitlow2009 Mitosis and Meiosis Review Cell Cycle Phases Description Phase Interphase Description G0 Cells are unlikely to undergo division in the near future. G1 G stands for ___________; During this phase the cell is…._________________________ S G2 ______________ Mitosis S stands for ____________; During this phase the DNA ______________ to produce __________________ chromosomes. The cell is undergoing the last preparations for divisions which include making more organelles. In animal cells, the ______________________must replicate for their role in mitosis. There are no ____________ in plant cells. The ________________ and _______________ disappear. The __________________________ become visible. Centrioles move to opposite ________________and begin making _________ _________ _________________ The chromosomes meet in the ____________________ of the cell. _________________ The sister chromatids _____________ and move toward ______________ poles. _________________ The two new ____________ begin to reappear as the new surrounding membrane is formed. Chromosomes begin to ________________ which makes them more difficult to see. Cytokinesis In animal cells, the cells ____________ in creating a cleavage furrow. Eventually the _______________is divided in half. In plant cells the new ________ _________ starts as a cell plate in the middle of the cell expanding outward. clwhitlow2009 What phase is depicted below? __________________ __________________ _____________________ ________________ Draw a replicated chromosome and label the sister chromatids and the centromere. ________________________ ____________________ Meiosis How many divisions in Meiosis? _________ Meiosis begins with ______ cell that is _____________ and ends with 4 cells that are haploid. What is the purpose of meiosis? _______________________________________________ What type of cells undergo meiosis? __________________________ Which phase of meiosis includes the following events: Crossing-over- ____________________ Separation of chromatids- _____________________ The pairing of homologous chromosomes- ____________________ Separation of homologous chromosomes- _____________________
