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 Ari reads the card table. Which choice says what one round of mitosis makes from one starting cell?
- 2 cells, after 1 division
- 1 cell, after 1 division
- 4 cells, after 2 divisions
- 4 cells, after 1 division
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, with half the chromosomes
- Different from the parent cell but identical to each other
- Different from each other, with a new mix of chromosomes
- Identical to each other and to the parent cell
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 is cut in half, 2n to n
- It doubles, n to 2n
- It stays the same, 2n to 2n
- It doubles, 2n to 4n
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?
- Mitosis, in body cells that divide
- Meiosis, in body cells that divide
- Meiosis, in cells that make egg and sperm cells
- Mitosis, in cells that make egg and sperm cells
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?
- Meiosis, which halves the chromosome number
- Meiosis, which makes two cells from one
- Mitosis, which keeps the chromosome number the same
- Mitosis, which makes four cells from one

- Joining an egg cell to a sperm cell
- Growth and repair of body tissue
- Making identical copies of body cells
- Making egg and sperm cells

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, using mitosis
- Asexual, using meiosis
- Sexual, because a new cell forms
Tala sees a strawberry plant grow a runner with a new plant at a node. How did the new plant begin?
- From the parent's cells dividing by mitosis
- From an egg cell and a sperm cell joining
- From the parent's cells dividing by meiosis
- From mitosis, with a new mix of chromosomes
