Guided Notes: Mitosis vs Meiosis Comparison Introduction meiosis cytokinsis - Biology often has similar-sounding terms like: __________, __________, and __________ mitosis meiosis - This video compares two important cellular processes: __________ and __________ mitosis Basic Comparison 2 identical diplod cells - Mitosis results in: __________ 4 non identical cells - Meiosis results in: __________ (also called gametes) Starting Cell diplod - Both processes start with a __________ cell (2n) 46 chromosomes (_____ - In humans, this means _____ _____ from dad) 23 from mom, 23 Interphase - Occurs before both processes duplicates its chromosomes - The cell __________ 46 chromosomes, but _____ 92 chromatids - After duplication, there are still _____ Stages (PMAT) 1. P__________ rophase visible - Mitosis: Chromosomes become __________ - Meiosis I: Chromosomes pair up with their __________ homologous partners etaphase 2. M__________ single - Mitosis: Chromosomes line up in a __________ file - Meiosis I: Chromosomes line up in __________ pairs naphase 3. A__________ sister chromosomes - Mitosis: __________ are pulled to opposite sides - Meiosis I: __________ are pulled to opposite sides homologous chromosomes elaphas nuclear membranes 4. T__________ - Both: Chromosomes at opposite ends, __________ reform e Cytokinesis cytoplasm - Follows both processes to split the __________ Results diplod 2 - Mitosis: _____ identical __________ cells haploid cells - Meiosis: _____ non-identical __________ 4 Fun Fact ants - Some insects, like __________, have only 6 chromosomes Final Note egg sperm - When a __________ and __________ combine, they form a __________, which then uses zygote mitosis to develop into a new organism __________
