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
