Mitosis Review Watch this video of the Mitosis song to help you review what goes on during Mitosis and the purpose of it. Then answer the questions below! (hope the song gets stuck in your head )P.S I recommend turning captions on and re-watching the video if you need! Fill in the blanks using the word bank! 1. In Mitosis, the mother cell divides to create 2 identical cells.2. Mitosis is used for growth and development: to replace the old, dead cells! 3. Before Mitosis happens, the cell must replicate its DNA. In the cell cycle, the Mitosis (M) phase is the ....... phase. First Last Middle Meiosis Watch this video to get an introduction to Meiosis. Answer the questions below from the video! Vocab Matching Match each vocabulary word to its appropriate definition! Gamete Sperm & Egg cells Chromosome Packaged DNA and proteins Interphase The stage of a cell's life where it grows, replicates DNA and carries out other processes. Homologous Chromosomes Chromosomes that are the same size and have the same genes in the same locations Nondisjunction When the chromosomes don't separate correctly during divison Fill in the blanks using the word bank! 1. Human cells have a total of 46 chromosomes. Sperm and egg cells have only 23chromosomes each.2. Meiosis is when a mother cell divides twice and creates a total of 4 daughter cells.3. During the first step of Meiosis, a very important process occurs called crossing over. This is when homologous chromosomespair up with each other and exchange their genetic information with each other,4. Crossing over is the reason why there is genetic variation, even in siblings who have the SAME parents!5. Meiosis in biological males produces sperm cells and meiosis in biological females produce egg cells. True or False:Each gamete produced at the end of Meiosis is genetically identical to on another. True False Which process does this photo represent? Mitosis Meiosis Replication Mutation Identifying Important Steps in Meiosis Draw a circle around where you seecrossing overin this Meiosis diagram.
