p. 284 A.Q. 1a, 2ab, 3ab, 4ab
1a. What are chromosomes?
1a. Chromosomes are bundles of DNA that store
most of a cell’s genetic information.
2a. What is the cell cycle?
2a. The cell cycle is a series of events
that a cell goes through as it grows and
divides.
Growth
Growth
2b. During which phase of the cell cycle
are chromosomes replicated?
2b. Chromosomes are replicated during
interphase.

3a. What happens during each of the four phases of mitosis? Write one or
two sentences for each phase.
3a. Prophase: DNA in the nucleus condenses and the spindle fibers begin to
form.
Metaphase: The chromosomes line up and the spindle fibers attach to
the centromeres.
Anaphase: The chromosomes separate and move to opposite of the cell.
Telophase: The chromosomes begin to unwind and the spindle fibers
begin to break apart.
3b. What do you predict would happen if the spindle fibers were disrupted
during metaphase?
3b. The centromeres would not attach to the spindle fibers and the
chromosomes could not be pulled apart during anaphase.

4a. What is cytokinesis and when does it occur?
4a. Cytokinesis is the division of the cytoplasm
and it occurs at the end of cell division.
4b. How does cytokinesis differ in animal and
plant cells?
4b. In animal cells, the cell membrane pinches in
half to form two cells. In plant cells, a cell plate
forms that gradually develops into cell
membranes separating the daughter cells.
Eventually, a cell wall forms between the two
daughter cells.
