2. What limits cell size?
Not enough DNA
Moving materials

3. What are the parts of the cell cycle?
Interphase
Mitosis
Cytokinesis

4. What are the parts of interphase?
G1 – First Growth Phase
S – Synthesis Phase
G2 – Second Growth Phase

5. What are the parts of mitosis?
Prophase
Metaphase
Anaphase
Telophase

12. B. A.

30. The division of the cytoplasm.

31. A nuclear envelope re-forms around each cluster of chromosomes.

32. The spindle begins to break apart, and a nucleolus becomes visible.

33. Chromosomes begins to unwind to form chromatin.

34. The centromeres that join the sister chromatids split, allowing the sister chromatids to separate and become individual chromosomes.

35. Chromosomes continue to move until they have separated into two groups near the poles of the spindle.

36. Chromosome line up in the middle/center of the cell.

37. Microtubules connect the centromere of each chromosome to the two poles of the spindle.

38. Chromosomes appear.

39. Centrioles move to opposite ends of the cell.

40. Spindle fibers become attached to the chromosomes at their centromere.

41. Nuclear membrane breaks down. Nucleolus disappears.

42. Includes G1, S and G2 Phase. Cell Grows and Replicates DNA.

43. Replication of DNA

44. Normal Cell Growth.

45. Final preparation for mitosis.

46. Why do our cells divide? Pass genetic information to new cells
Reproduction
Growth
Replace old cells/dying cells
Replace damaged or missing cells.
