Presentation transcript:

Aim: How does the nucleus control the activities of the cell? There are two main functions of the nucleus: 1.Contains the codes  protein 2. Cell division

Task Arrange the cell according to how you think the cell reproduces Questions: What do you notice about the first and last cell? How are they the same/different ?

K-W-L What do you know, want to know about cell division? KWL

How does the nucleus direct the cell to reproduce ? Interphase Prophase Metaphase Anaphase TelophaseInterphase

Part I Information Gathering: the story of Sheena Read the story of Sheena Gather information on cancer Fill out the worksheet and use your text as a reference pg 245

What information did you find about the cell cycle? Each group will answer one question

Explain what happens to the cell and the chromosomes during each phase.

Historical Perspective of Cancer

Aim: What are the changes in the nucleus during cell division?

Each cell is identical to the mother cell Artificially colored bacteria cells dividing by mitosis, as seen using a scanning electron microscope

Chromosome duplication Chromosomes can be seen when they double

DNA's Feat: Making Two Out of One

Two Strands Of The Same Chromosome Have Formed

Mitosis Start with one cell End with two cells each with the exact number of chromosomes
