5. Label the pictures with the cell division phases: interphase, prophase, metaphase, anaphase, telophase, cytokinesis Goal: Understand How Cells Divide by Mitosis New Words: mitosis, prophase, metaphase, anaphase, telophase Anaphase Prophase Metaphase Cytokinesis TelophaseInterphase

EventsCell Cycle Phase Chromosomes are replicated Spindle fibers pull chromosomes apart to opposite end of the cell Nuclear membrane dissolves Increasing cell size and grow Production of many organelles and molecules Centrioles and spindle fibers become non-visible Chromosomes line up in the middle of the nucleus Spindle fibers attach to each chromosome at the centromere Wind DNA ( chromatin) into chromosomes Cell splits with its own set of chromosomes Nuclear membrane forms DNA unwinds into chromatin anaphase interphase Interphase interphase prophase metaphase prophase telophase Goal: Understand How Cells Divide by Mitosis New Words: chromosome, chromatin, centromere, chromatid cytokinesis

Goal: Understand How Cells Divide by Mitosis New Words: mitosis, prophase, metaphase, anaphase, telophase A. Chromosomes line up in the middle of the nucleus B. Chromatids move to opposite end of the cell C. Nuclear membrane dissolves D. Cell splits with its own set of chromosomes E. Cell grows and DNA replicates Do Now: 1. Interphase 2. Prophase 3. Metaphase 4. Anaphase 5. Telophase

Spindle fibers pull chromatids apart to opposite end of the cell DNA is replicated Nuclear membrane dissolves Increasing cell size and grow Production of many organelles and molecules Chromosomes line up in the middle of the cell Spindle fibers attach to each chromosome at the centromere Wind DNA ( chromatin) into chromosomes Nuclear membrane forms DNA unwinds into chromatin Interphase Prophase Metaphase Anaphase Telophase Centrioles and spindle fibers become visible Centrioles and spindle fibers become non visible Goal: Understand How Cells Divide by Mitosis New Words: mitosis, prophase, metaphase, anaphase, telophase Cytokinesis Cell splits with its own set of chromosomes

Mitosis Number of cell division? Exchange of genetic material between chromosomes? Number of functioning cell produced from the original? Number of chromosomes of daughter cells compare to parent cells How is the genetic material of final cells produced? Function of cells produced? One No Two daughter cells Equal number In human is 46 chromosomes Identical as the original Growth or replacement of body cells Same as the parent cells Goal: Understand How Cells Divide by Mitosis New Words: mitosis, prophase, metaphase, anaphase, telophase

Goal: Understand How Cells Divide by Mitosis New Words: mitosis, prophase, metaphase, anaphase, telophase Cell Cycle Project Goal: Make a poster of the cell cycle that depicts the different stages with pictures and photographs, and explains the major events of each phase. Materials: Chart paper, mitosis pictures and photos, markers, tape, glue, scissors, and books or other sources of information. Due day: Friday, September 15th. Rubric: Total # of point is 100. Centrioles Chromatin Interphase Nuclear envelope Cytokinesis Nuclear envelope reforming TelophaseAnaphase Individual chromosomes Metaphase Centriole Spindle Centriole Chromosomes (paired chromatids) Prophase Centromere Spindle forming Section 10-2

Goal: Understand How Cells Divide by Mitosis New Words: mitosis, prophase, metaphase, anaphase, telophase Performance IndicatorsPoints Poster includes pictures and photographs of interphase and all mitosis phases in order.(10 points) Pictures and photographs are label as:  Interphase Mitosis  Prophase Metaphase  Anaphase Telophase  Cytokinesis (20 points) All pictures and photographs are properly labeled with the following tags:  Nucleus nuclear membrane  Chromatin chromosomes  Chromatids centrioles  cell membrane spindle fiber (25 points) The main events of each phase are described correctly:  Cell splits with its own set of chromosomes  Chromosomes are replicated  Spindle fibers pull chromosomes apart to opposite end of the cell  Nuclear membrane dissolves  Increasing cell size and grow  Production of many organelles and molecules  Centrioles and spindle fibers become non-visible  Chromosomes line up in the middle of the nucleus  Spindle fibers attach to each chromosome at the centromere  Wind DNA ( chromatin) into chromosomes  Nuclear membrane forms  DNA unwinds into chromatin (25 points) Product is neat and well organized(10 points) All group members participate and work actively in the poster.(10 points)

Do Now 1. Describe what the pictures below show 2. What type of division do you see in this illustration? 3. What does “46” stand for? 4. Compare parent cell’s DNA to daughter cell’s DNA Goal: Understand Mitotic Cell Division New Words: mitosis, mitotic cell division
