Check Your Understanding Questions page 151 #2-7 Activity 5-1C Observing the Cell Cycle in Plant Cells ġ3 ASEXUAL REPRODUCTION Only 1 parent is involved. State DNA is not visible in a cell unless it is undergoing division. Include Media presentations of Mitosis and stages as well as have the students look through a microscope. Interactive web-siteġ1 Activity 5-1C Observing the Cell Cycle in Plant Cells Have students look atġ0 Cytokinesis: The phase in the life cycle of a cell which separates the 2 cell nuclei and contents into 2 daughter cells after mitosis. Also could do a choice of assignment porfolio ideas including a mitosis flip book or creating a poster with string or pipe cleaners or other representation they prefer. Have students reinact the process of mitosis acording to guided activity provided.
The cell is ready to divide into 2 separate cells. Use Blackline Master 2-10 for simple note taking, could Include Flip book activity or worksheets form 3D posters informationĦ PROPHASE The double stranded chromosomes (DNA) shorten and thickenħ METAPHASE X-shaped chromosomes are pulled into a single line across the middle of the cell.Ĩ ANAPHASE The x-shaped sister chromatids are pulled to opposite poles of the cell.ĩ TELOPHASE The nuclear membrane forms around each set of chromosomes. Use Blackline Masters and Use for Evaluation Ask the question wether they would rather have 1 million dollars or the amount of money you would have if you place a penny on a chess board and doubled the amount every block (64 blocks) would result in approximately 9.2 x 1018 pennies, at 30 there would be, over taking a million at block 28! Activity 5-1A From one Cell to Many Cells ĥ Prophase Metaphase Anaphase Telophase Stages of Mitosis
Stomach lining cells about 2 days, red blood cells about 120 days, brain cells years and do not renew! Liver cells about 200 daysĤ Activity 5-1A From one Cell to Many Cells Not all have the same rate of cell reproduction, skin cells renew every days. Instruct that all cells except the gametes use mitosis for growth and or cell replacement. 1 Mitosis is the Basis of Asexual ReproductionĬhapter 5 Mitosis is the Basis of Asexual Reproductionģ Mitosis page 142 The Process by which the content in a cell’s nucleus divides Results in 2 daughter cells nuclei each with the same number and kinds of chromosomes as the parent cell “Marathon” writing activity suggested to tap into what students know about how cells are involved in growth and reproduction.
