Cell division jobs for an animal (facts from OpenStax Biology 2e)
process daughter cells where it happens purpose mitosis identical body cells that divide growth and repair meiosis different from each other cells that make egg and sperm cells making egg and sperm cells Bo reads the card table. Which choice describes the daughter cells made by mitosis?
- Identical to each other and to the parent cell
- Identical to each other, with half the chromosomes
- Different from the parent cell but identical to each other
- Different from each other, with a new mix of chromosomes
Cell division counts for an animal, usual case (facts from OpenStax Biology 2e)
process divisions cells made chromosome number mitosis 1 2 2n to 2n meiosis 2 4 2n to n Esme reads the card table. What happens to the chromosome number in mitosis?
- It doubles, 2n to 4n
- It stays the same, 2n to 2n
- It is cut in half, 2n to n
- It doubles, n to 2n
Cell division jobs for an animal (facts from OpenStax Biology 2e)
process daughter cells where it happens purpose mitosis identical body cells that divide growth and repair meiosis different from each other cells that make egg and sperm cells making egg and sperm cells Jun reads that a young animal grows as its body cells divide. Which choice names the process and where it happens?
- Meiosis, in body cells that divide
- Meiosis, in cells that make egg and sperm cells
- Mitosis, in body cells that divide
- Mitosis, in cells that make egg and sperm cells
Kira reads the card table. Which job does meiosis do in an animal?
- Makes new body cells so the animal can grow
- Repairs body tissue by copying cells
- Makes egg and sperm cells that copy the body cell exactly
- Makes egg and sperm cells with half the chromosomes
Cell division counts for an animal, usual case (facts from OpenStax Biology 2e)
process divisions cells made chromosome number mitosis 1 2 2n to 2n meiosis 2 4 2n to n Luz reads a card: two divisions in a row, four cells. Which choice names the process and what happens to its chromosome number?
- Mitosis, which keeps the chromosome number the same
- Mitosis, which makes four cells from one
- Meiosis, which halves the chromosome number
- Meiosis, which makes two cells from one

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.
Ren reads that a yeast cell forms a bud that pinches off. Which choice names the reproduction and the division used?
- Asexual, using mitosis
- Sexual, because a new cell forms
- Sexual, using mitosis
- Asexual, using meiosis
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
