Growth Pass traits Use energy Repair Replacement Release CO2 Limit size Food 2. Match the following: ____ Interphase a). In this stage of the cell cycle, the chromosomes are not yet visible, but they are making copies of themselves, preparing for cell division. b). In this stage of mitosis, the chromosomes line up in the middle of the cell and attach to the spindle fibers. c). In this stage of mitosis, the spindle fibers form, the chromosomes pair up, and the nuclear membrane breaks apart. d). In this stage of mitosis, the nuclear membrane reforms around the chromosomes in preparation for becoming two, identical cells. e). In this stage of mitosis, the chromosomes move apart towards the centrioles at opposite ends of the cell. f). In this stage of the cell cycle, you have two new daughter cells. ____ Metaphase ____ Prophase ____ Anaphase ____ Cytokinesis ____ Telophase 3.
