Cell Division: Mitosis & Meiosis

Master cell division! Learn mitosis & meiosis, their stages, and key differences.

When does the cell replicate its DNA (make a second copy)? it only duplicates the DNA for mitosis during interphase, before mitosis meiosis start during prophase I during Telophase II, after meiosis is complete What phase of the cell cycle does a cell stay in the longest? meiosis mitosis cytokinesis interphase How are mitosis and meiosis different from cytokinesis? mitosis meiosis divide the cytoplasm, cytokinesis divides the nucleus mitosis meiosis divide the nucleus; cytokinesis divides the cytoplasm cytokinesis happens first; mitosis meiosis happens second What process in Prophase I results in chromosomes with new combinations of genes? spindle apparatus tetrad crossing over (synapsis) replication What is the main difference between cytokinesis in plants and animals? Stages of Mitosis Match each phase of mitosis with the appropriate description. Prophase Nuclear envelope breaks down so that spindle fibers can attach to the chromosomes. Metaphase Chromosomes line up in the middle of the cell. Anaphase Chromosomes are pulled apart to opposite ends of the cell. Telophase Cell divides into two cells. Stages of Mitosis Match each phase of mitosis with the appropriate picture. Prophase Metaphase Anaphase Telophase Stages of Meiosis Match each phase of meiosis with the appropriate description. Prophase I Homologous chromosomes pair up and crossing over occurs. Metaphase I Homologous chromosomes line up in the middle of the cell. Anaphase I Individual chromosomes are pulled apart to opposite ends of the cell. Telophase I Cell divides into two cells. Prophase II Spindle fibers attach to individual chromosomes. Metaphase II Individual chromosomes line up in the middle of the cell. Anaphase II Sister chromatids are pulled apart to opposite ends of the cell. Telophase II Two cells divide into four cells. Stages of Meiosis Match each phase of meiosis with the appropriate picture. Look carefully at the number of chromosomes to determine if the cell is in metaphase I or metaphase II, anaphase I or anaphase II, etc. Prophase I Metaphase I Anaphase I Telophase I Prophase II Metaphase II Anaphase II Telophase II Meiosis VS Mitosis Sort each item into whether it is part of mitosis, meiosis, or both! Mitosis cell goes through 1 division cells produced are identical to the original cell cells produced have the same number of chromosomes as the parent cell 2 somatic cells are produced Meiosis cell goes through 2 divisions cells produced are unique cells produced have half the number of chromosomes as the parent cell 4 gametes are produced Both Interphase occurs before involves the PMAT phases
