Cell division quiz Define the following
Centrioles: Every animal cell has two (help with cell division)
Mitosis: The division of the nucleus
Cytokinesis: The division of the parent cell’s cytoplasm (happens during last phase
of mitosis)
What happens during interphase: Cell grows and at the end of cycle the
chromosomes double
What happens during prophase:
 Cell division begins
 chromatin condenses into chromosomes – (each chromosome consists of
two chromatids held together by a centromere)
 Nuclear membrane disappears
What happens during metaphase:
 Chromosomes line up in the middle of the cell.
What happens during anaphase:
 Chromatids separate and are pulled to opposite sides of the cell
What happens during telophase:
 Two new nuclear membranes form
 Cytokinesis begins
What are the differences between plant and animal cells:
 Plant cells have a cell plate
 Animal cells pinch in to split into two
 Animal cells have centrioles
What is the period of growth called in the life of a cell?: Interphase
