1. Telophase is a phase of mitosis
and the other three are phases of interphase
Interphase is a phase of the cell cycle
and the other three are phases of mitosis
Binary fission pertains to prokaryotes
and the other three pertain to eukaryotes
Spindle fiber pertains to nuclear
division and the other three pertain to cytoplasmic division
Vesicles are organelles but are not
directly involved with nuclear division as are the other three

3. 1) G1: cell grows
2) S: DNA is replicated
3) G2: cell prepares for cell division
4) Mitosis: nucleus divides
5) Cytokinesis: cytoplasm divides

4. 1) Prophase: chromatin coils into replicated chromosomes;
centrosomes start to move and generate spindle fibers
(Prometaphase/Late Prophase: nuclear envelope breaks up;
spindle fibers attach to kinetochores)
2) Metaphase: spindle fibers align replicated chromosomes at
cell equator
3) Anaphase: spindle fibers retract, pulling apart sister
chromatids at the centromere; individual chromosomes are
pulled to opposite ends of the cells
4) Telophase: spindle fibers disappear; nuclear envelope and
nucleolus reform; individual chromosomes unwind to
chromatin

5. Vesicles from the Golgi apparatus carrying cellulose fibers fuse at the midline of the cell to form the cell plate. These elongate and eventually become the new cell wall that separates the cell into two cells.
Without a G1 growth phase, the cells would not grow to their mature size after cytokinesis. Therefore the daughter cells would become smaller and smaller with each cell cycle.
