Mitosis Prophase • Chromosomes Condense or Thicken. • Centrioles move to the poles (sides they want to be the opposite of each other. • Spindles (fibers form) • Nuclear envelope dissolves releasing the chromosones Metaphase Anaphase Telophase Cytokinesis Cytokinesis – Animal Cells Cytokinesis – Plant Cells Phase Phase Phase Phase Phase Phase Phase Mitosis Prophase Metaphase Anaphase Telophase Cytokinesis Cytokinesis – Animal Cells Cytokinesis – Plant Cells Phase Phase Phase Phase Phase Phase Phase Phase chromosome (unduplicated) in cell at interphase same chromosome (duplicated) in interphase prior to mitosis mitosis, cytoplasmic division chromosome (unduplicated) in daughter cell at interphase chromosome (unduplicated) in daughter cell at interphase chromosome (unduplicated) in cell at interphase same chromosome (duplicated) in interphase prior to mitosis mitosis, cytoplasmic division chromosome (unduplicated) in daughter cell at interphase chromosome (unduplicated) in daughter cell at interphase Cell Division Review Metaphase Interphase Telophase Prophase Cytokinesis Telophase Prophase Anaphase Interphase Cytokinesis Metaphase Prophase Telophase Anaphase Metaphase Prophase Anaphase Cytokinesis What are structures labeled “B”? SISTER CHROMATIDS Uncontrolled cell growth is the main cause of ____________. CANCER Mitosis produces two new _____________ daughter cells. IDENTICAL The process that allows stem cells to become any other type of cell in the body is called? Differentiation List the internal structures of a chromosomes from smallest to largest. DNA, Nucleosome, Coil, Supercoil, Chromosome What is an advantage of sexual reproduction? Produces genetically diverse offspring Why is it important for cells to stay small? Smaller cells are more efficient at transporting materials into/out of the cell. What are the three phases of Interphase? G1 phase, S phase, & G2 phase The term “totipotent” means? Cells that can differentiate into any type other cell or tissue. What is the role of spindle fibers during mitosis? They help separate the chromosomes between metaphase & anaphase. The two stages of cell division or M phase are? Mitosis & Cytokinesis Growth factors are proteins that… REGULATE THE CELL CYCLE Cancer cells form masses of cells called? TUMORS What is the first phase of mitosis? PROPHASE What is the structure labeled “A”? CENTROMERE What occurs during the “G” phases of Interphase? The cell grows and prepares for division (mitosis). During cytokinesis, what develops in plant cells but NOT in animal cells? A CELL PLATE How long does the ENTIRE cell cycle take? 24 hours How long does MITOSIS take? 80 minutes
