During the Telophase, it actually pinch off into two separate beings. The third phase is where the chromosomes (DNA) begins to split and move itself into two cells. The second phase is called Metaphase this is where the DNA lines up in the middle of it. This is where the cell duplicates its DNA. There are five phases associated with this process. To do this they undergo a process of duplicating themselves. To make sure organisms can continue to survive, they constantly need to make new copies of them. Keep reading to learn more about how both of these processes work.Īll body cells have a short life span. The primary difference between the two is how the chromosomes are separated and recombined, an essential part of human reproduction. Mitosis produces most of your body’s cells, your bones, organs, and muscles meiosis only produces eggs in women and sperm in males. Meiosis is used in the sex organs and results in four haploid (23 chromosome) sex cells. Mitosis is the process used in most cells and results in two diploid (46 chromosome) daughters. Mitosis and meiosis are the two different types of cell division. But how exactly does this complicated process work? Our bodies create slightly different sex cells to create eggs and sperm, each containing exactly half of our genetic information. The human body is an amazing thing it contains trillions of cells which all replace themselves by dividing into two duplicates. What Is the Difference Between Mitosis and Meiosis? Simulate mitosis and meiosis in an imaginary animal called a Frimpanzee ( doc).Do the “ Modeling Meiosis” Lab using modeling clay of different colors to represent the chromosomes.Another good “ Stages of Mitosis” lab using onion root tip slides.
Have students do this “Observing Mitosis Lab” ( pdf) using prepared slides of onion ( Allium) root tips.Watch Frank Gregorio’s very dramatic YouTube video of “ Cell Division and the Cell Cycle.”.Show Michael Clark’s “Mitosis” PowerPoint presentation.Scott Greenhalgh from the NSTA Listserve contributed this “Meiosis Web Lesson” ( doc) that uses this Meiosis Animation.
You will need to save the file and open it in PowerPoint to have the music play throughout. “It’s Mitosis Time” ( ppt) is a Karaoke PowerPoint set to the music of “Celebration Time” by Kool and the Gang.“ Mitosis & Mitosis: Doing It On the Table ” is and activity designed to help students to learn the critical distinctions between what happens to chromosomes during mitosis vs meiosis.In “ Online Onion Root Tips” students identify the phases of mitosis and determine the time spent in time spent in different phases of the cell cycle.Using the Cells Alive website, Maria Ferraro contributed this “The Cell Cycle and Animal Cell Mitosis” ( doc) worksheet.If your school has this program, creating your own maps is a good way to introduce vocabulary. It includes information about meiosis and fertilization with questions. Using the Inspiration software, Sue Hinojoza has created a concept map about “Chromosomes” ( pdf).Try this simple “Modeling Crossing Over” ( doc) activity.
