| A | B |
|---|
| Interphase functions | chromosomes replicate, cytoplasm increases, cells prepare to divide |
| Prophase functions | sister chromotoids condense to become thicker, nucleolus and nuclear envelope divide, microtubules that mkae up the spindle fibers begin to disappear |
| Metaphase functions | chromosomes are moved to center of cell by the spindle fibers atached to centromeres, 2 sister chormotids of each chromosome are attached to spinle fibers radiating from the opposite ends of the cell |
| Anaphase functions | the centromeres of each chromosome are pulled towards the ends of the cell by spindle fibers, and sister chromotids are separated |
| Telophase functions | new nuclei begin to form around the chromosomes at each end of the cell, cell membrane begins to pinch the cell into two, and cytokinesis begins |
| cleavage furrow | groove that forms in the middle of the parent cell for cytoplasm to divide in animal cells |
| equator | middle of the cell, between the two nuclei |
| animal cell cytokinesis | cytoplasm divides when cleavage furrow forms |
| plant cell cytokinesis | materials for new cell walls and membranes gather and fuse along the equator |
