Write the letter or letters that describe a diploid cell in the blank to the left. Try again! So, the answer would be 4.
Meiosis Puzzle Activity
The diploid cell that enters meiosis becomes 4 haploid cells at the end of meiosis. Each chromosome is two chromatids and a tetrad is composed of two chromosomes. Write the number of chromatids in a tetrad in the blank to the left. What is the result of the process of crossing-over during prophase I Crossing over exchanges alleles and allows for genetic variation in offspring.

English Language Arts. Foreign Language. Social Studies - History. History World History. For All Subject Areas.This lab is a great way to make the many phases of meiosis make sense! Having kids work through each phase using the colored beads slows down their conversation and thinking and brings up great questions that help propel them forward to deeper understanding of how mitosis and meiosis compare to each other.
It also connects back to our work on the differences between cell division in cancer cells vs. I typically keep the beads out in the classroom so that students can use them as we talk throughout the unit.
Remind students of the work you did in your last session together comparing and contrasting the events in mitosis and meiosis. Tell students that today they will be working with their lab partner using bead models to explore the process of meiosis in more detail. Pass out the modeling meiosis bead lab document. Let students briefly read over the directions for this document and then highlight the procedure and goals:.
Ask students to go to their lab tables where they will find their beads and colored pencils in order to begin their pair activity.
Once student pairs arrive at their lab tables, give them five minutes to settle in, look at their materials, consult their activity document, and check in as a team. At this point, all groups should be working with the beads.
Circulate as student groups are working. Listen in to see how students are working with their partners and within their table groups to help each other. Below you will find photos of each of the phases of meiosis that students will be simulating with the beads. I am including them here for you to give you a sense of how the flow of events in meiosis translates into our bead models.
Also, you can use these photos later on as a way to help students recall what they know about each phase, specifically as a prompt for vocabulary or even as a writing activity. Interphase I G1 beads. Interphase I Sunthesis beads. Prophase I beads. Crossing Over in Prophase I beads. Metaphase I beads. Anaphase I beads. Metaphase II beads. Anaphase II beads. Telophase II beads.
About halfway through the session, you will notice that students are working with the models with more confidence and ease. Encourage pairs you saw struggling earlier to revisit their initial responses now that they are more comfortable with both the activity and the process of meiosis.
As the activity winds down, ask students to return their materials to their designated spot in the room and return to their desks for our final wrap up. Using the spokesperson protocolask students to share out their answers to the following two prompts:.
Ask students for any questions about meiosis that came up during the lab session. Check out two student work samples below. I chose these two examples as representative of most work I received and two things stand out to me:. Empty Layer. Home Professional Learning. Professional Learning.

The Classroom Flow: Reviewing Concepts.Most of the time, when a cell in our bodies divides, each new cell carries a complete set of chromosomes. The cells involved with human reproduction, however, carry only half after division occurs.
In this step-by-step explanation, learn about mitosis and meiosis, the two types of cell division. Explore the stages of two types of cell division, mitosis and meiosis, and how these processes compare to one another.
As viewed from a human perspective, nature seems to have done ingenious engineering to overcome obstacles. Take the evolution of sex, for instance.
To make the move from asexual to sexual reproduction, nature took a system by which parent cells reproduced simply by dividing asexual reproduction and altered it to allow two parent cells to combine to create offspring sexual reproduction. Asexual reproduction relies on a process called mitosis, in which the nucleus of a cell divides to create two new nuclei, each containing an identical copy of DNA.
Mitosis allows the cells in your body to divide and regenerate—your hair to grow, your skin to heal after being wounded. Almost all of the DNA duplication in your body is carried out through mitosis. Meiosis, on the other hand, is the process by which certain sex cells are created.
If you're male, your body uses meiosis to create sperm cells; if you're female, it uses meiosis to create egg cells. While all other cells in your body contain 46 chromosomes 23 from your father and 23 from your motheryour egg or sperm cells contain only half that number—a total of 23 chromosomes.
When an egg and sperm unite to make a fertilized egg, the chromosomes add up to equal How exactly does meiosis halve and mix chromosomes? Find out through this feature, which provides a step-by-step, side-by-side comparison of meiosis and mitosis. Find out what separates life from nonlife, and glimpse how scientists are exploring the boundary.

I n this exercise, the original cell starts with six chromosomes, so the following supplies are needed. It helps keep materials organized if interlocking beads and string are each in separate, smaller baggies.
Photo 1. First string one interlocking bead onto each strand of chromatin. Set one of each type of pipe cleaner 6 aside. Those will come into play when DNA replicates. Photo 2. It makes exercise too complicated and messy. Photo 3. Snap together the two interlocking beads that represent the centromeres, bringing the other six pipe cleaners into play. Photo 4. Close-up of replicated chromatin.
Meiosis I:. Prophase Ichromatin condenses into chromosomes. Twist pipe cleaners so that they are curly. Metaphase Ihomologous chromosomes line up at cell equator. Anaphase Ihomologous chromosomes move toward opposite poles of the cell.
