Most cells in an organism go through a
cycle of growth,development, and division
called the cell cycle
* Chapter 3: From a cell to an organism
Lesson # 1: cell cycle and cell division
Objective: Observe how can one cell become a
multicellular organism

Mitosis phases:
Prophase: Nucleolus disappears and nuclear membrane breaks down
Methaphase: Chromosomes line up in single file
Anaphase: sister chromatids separate, spindle fibers begin to shorten
Telophase: nuclear membrane forms around the chromatin, two identical nuclei form
