Want to help your students better understand mitosis and meiosis? I teach my students about ploidy (haploid, diploid, triploid, and tetraploid) before I get into mitosis or meiosis and I use this worksheet to challenge their understanding.
This lesson is great to use after you have taught the concepts of haploid, diploid, triploid, tetraploid, haploid number, and diploid number
. Students may initially think they understand the concept of ploidy, but when they do this worksheet, they will realize it is more difficult than they initially thought! The worksheet seems deceptively simple at first, but it will definitely get your students to think more deeply. If my students complete this before we go into mitosis and meiosis, they understand mitosis and meiosis better than the students who have not completed this worksheet. I have used this worksheet in all levels of classes.
With each diagram, students are asked the following questions:
a. How many sets of similar chromosomes are there?
b. How many chromosomes are in each set?
c. Is the cell haploid, diploid, triploid, or tetraploid?
d. How many chromosomes does each cell have?
e. What is haploid number for this organism, if the organism also produced haploid cells?
f. What is the diploid number for this organism, if the organism also produced diploid cells?
