Mitosis and Meiosis Review

Master mitosis and meiosis! Review cell division phases, compare processes, and label diagrams.

Match the following phases of meiosis with their descriptions. Prophase 1 Nuclear membrane dissolves, chromatin condenses to chromosomes and the spindle fiber forms. Crossing over occurs now. Metaphase 1 Homologous pairs line up on the equator (middle) of the cell Anaphase 1 Homologous pairs separate to opposite sides of the cell as spindle fibers retract into centrioles Telophase 1 The cell membrane pinches in, the nuclear membrane reforms and chromosomes uncoil to chromatin Telophase 2 Nuclear envelopes reform around daughter cells and is then divided into 4 separate daughter cells Meiosis vs. Mitosis Sort each statement into the meiosis OR mitosis box. Meiosis Sex cells (gametes) are produced Goes through each phase twice Results in 4 daughter cells Daughter cells are haploid Daughter cells are genetically different than the parent cell Homologous chromosomes pair up during prophase Crossing over occurs Mitosis Body (somatic) cells are produced Goes through each phase once Results in 2 daughter cells Daughter cells are diploid Daughter cells are genetically identical to the parent cell Fill in the blanks to complete the paragraph. Cells that begin meiosis are diploid because they have the full number of chromosomes. These cells have pairs of chromosomes. These pairs are called homologous pairs.One comes from the egg (mother) and the other comes from the sperm (father). These chromosomes are identical.They have information for the same genes but the information may be different because the information is coming from two different people. By the end of the meiosis, the cells that are produced have the haploid number of chromosomes.
