{ #2 – How many phases are in the ENTIRE cell cycle? SIX!!

LOOONNNNGEST phase?? INTERPHASE Chromosomes are copied!

 1. How would I compare the phases of the Cell Cycle?  2. What does = 2 mean (in relation to the cell cycle) Today I will answer….

Chromosomes (c.) are copied (# doubles) C. appear as threadlike coils (chromatin) Copied c. = sister chromatids What happens

Interphase – Longest Phase Animal Cell Plant Cell Photographs from:

DNA forms chromosomes Centrioles appear & spindle fibers form between the poles What happens

Prophase Animal Cell Plant Cell Photographs from: Spindle fibers

C. line up in the middle Chromatids (pairs of c.) attach to the spindle fibers What happens

Metaphase Animal Cell Plant Cell Photographs from:

Chromatids (pairs of c.) separate and move apart to opposite ends What happens

Anaphase Animal Cell Plant Cell Photographs from:

C. unwind (chromatin again) Cell pinches inward Mitosis ends What happens

Telophase Animal Cell Plant Cell Photographs from:

What happens Cytoplasm divides One cell becomes 2 IDENTICAL cells

Cell Cycle Foldable Front: ▫Write the Cell Cycle on the top ▫Draw picture (from p. 156) Inside (each flap) ▫Name of phase (p ) ▫Picture (p ) ▫Under the flap – Write the summary Color all when finished
