Use this
Two ways to reproduce (facts from OpenStax Biology 2e), 2 rows. Columns: way, starting cells, how offspring begin, offspring. asexual, such as budding yeast, 1 parent, a bud forms and the nucleus divides by mitosis, match the parent. sexual, usually 2 parents, an egg cell and a sperm cell join, differ from each other and from the parents.
8.
Ren reads that a yeast cell forms a bud that pinches off. Which choice names the reproduction and the division used?
- Asexual, using meiosis
- Sexual, using mitosis
- Asexual, using mitosis
- Sexual, because a new cell forms
9.
Tala sees a strawberry plant grow a runner with a new plant at a node. How did the new plant begin?
- From mitosis, with a new mix of chromosomes
- From the parent's cells dividing by meiosis
- From the parent's cells dividing by mitosis
- From an egg cell and a sperm cell joining
10.
Zee reads that an animal's egg cell and sperm cell join to start a new organism. Which choice names this reproduction?
- Asexual, because meiosis made the cells that joined
- Asexual, because one parent is needed
- Sexual, because mitosis made both cells
- Sexual, because two cells join

About this worksheet

Mitosis and meiosis compared. Every version has 10 questions, and the answer key prints on the second page.

What your child will learn

I can read the two-row card table and say that mitosis is 1 division that makes 2 cells (2n to 2n, identical) and meiosis is 2 divisions that make 4 cells (2n to n, different from each other).
I can say where each happens in an animal (mitosis in body cells that divide; meiosis in the cells that make egg and sperm cells) and what each is for (growth and repair; making egg and sperm cells).
I can work out the chromosomes in a model cell after each process (2n = 8: mitosis gives 8 in each of 2 cells; 2n = 10: meiosis gives 5 in each of 4 cells) and the total in all the cells (2n = 4: meiosis makes 4 cells with 2 each, 8 in all).
I can classify a described division from its numbers (1 division, 2 cells, the same chromosomes: mitosis; 2 divisions, 4 cells, half the chromosomes, all different: meiosis).
I can say what the two processes share (one round of chromosome copying first) and what only one of them has (two divisions in meiosis; the parent's number in mitosis).
I can say that when an egg cell and a sperm cell join, their numbers add back to 2n (3 + 3 = 6), and that this is why meiosis halves the number.

Standard: HS-LS3-2

Words to know

mitosis: One division of a cell's nucleus that makes two cells identical to the parent cell

meiosis: Two divisions in a row that make four cells with half the chromosomes

chromosome: A long piece of DNA with its proteins; each species has a set number

diploid (2n): Having two sets of chromosomes, one from each parent

haploid (n): Having one set of chromosomes, as egg and sperm cells do

body cell: A cell of the body that is not an egg or sperm cell

germ cell: A cell that can divide by mitosis or make egg and sperm cells by meiosis

gamete: An egg cell or a sperm cell

Common mistakes

Your child said mitosis halves the chromosome number. Mitosis keeps the number, and meiosis is the division that halves it. Ask your child what 2n becomes in each process.

Your child said the cells made by meiosis are identical. Meiosis makes cells that differ from each other, and mitosis makes cells that match. Ask your child which process makes cells that match the parent.

Your child said mitosis makes four cells. Mitosis makes two cells in one division, and meiosis makes four cells in two divisions. Ask your child how many divisions each process takes.

Questions parents ask

What is the most common mistake with mitosis and meiosis compared?

Your child said mitosis halves the chromosome number. Mitosis keeps the number, and meiosis is the division that halves it. Ask your child what 2n becomes in each process.
