Mitosis vs. Meiosis Review

Write your first and last name in the space below. Mitosis vs. Meiosis Side-by-Side Comparison Video Use the video below to help you with this worksheet. The video is not worth any points, but is posted here as a resource if you need it. Cell Labeling: Label the following parts on the cell using the word bank below. Spelling is very important so you may want to copy paste the words from below:centrioles spindle fibers chromosome nuclear membrane chromosome centrioles spindle fibers nuclear membrane Meiosis Diagram: Meiosis Phases: Use the image of meiosis above to help you match each phase of meiosis with the appropriate description. You do not need to drag the line across to connect each dot. Instead, click on the dot on the left and then click on the dot on the right to connect the two. Prophase I Crossing over occurs resulting in recombinant chromosomes that show genetic variation Metaphase I Homologous chromosomes line up in pairs in the middle Anaphase I Homologous chromosomes separate and move apart to opposite sides of the cell Metaphase II Chromosomes line up single file in the middle of the cell Anaphase II Sister chromatids move apart to opposite sides of the cell What phase (including G1, S, and G2) occurs before both mitosis and meiosis? interphase cytokinesis telophase biophase What major event happens during the S (synthesis) part of interphase? (HINT: this process produces identical copies of DNA) Photosynthesis Dehydration synthesis Crossing over DNA replication What is the correct sequence of phases for both mitosis and meiosis? (the first letter of each phase is used --> example P = prophase) PATM TAPM PMAT APMT Mitosis vs. Meiosis Sort: Classify each statement with the process it belongs to. Hint: you will classify 7 statements into each process. The Cell Cycle with Mitosis used for growth, repair, and regeneration goes through PMAT once Only 1 cell division results in 2 daughter cells makes identical cells Daughter cells are diploid (in humans, have 46 chromosomes) Makes body (somatic) cells The Cell Cycle with Meiosis used for sexual reproduction goes through PMAT twice results in 4 daughter cells makes unique, different cells Makes reproductive cells (gametes) Daughter cells are haploid (in humans, would have 23 chromosomes) Crossing over occurs and results in genetic variation House cats have 38 chromosomes in their body cells. After mitosis, how many chromosomes would be in each of the daughter cells? 38 76 19 Potatoes have 46 chromosomes in their cells. After mitosis, how many chromosomes would in each of the daughter cells? 23 46 92 Narwhals have 44 chromosomes. After meiosis, how many chromosomes would be in each of the daughter cells? 22 44 88
