Question

name
cell division
identify: use the word bank to identify each term described
mother cell interphase cytokinesis prophase
meiosis mitosis daughter cells binary fission
anaphase diploids metaphase telophase

1. the chromosomes separate and move to the

opposite sides of the cell in this phase of mitosis

1. the normal state of a cell
2. the splitting of the cells in mitosis
3. process that makes an exact copy of a cell
4. process used when it is time for an entire

organism to reproduce

1. original cell
2. the cell walls pinch off and split down the middle

during this phase of mitosis

1. the new cells produced
2. cells produced from mitosis because they have

two complete sets of chromosomes

1. first step of mitosis
2. part of mitosis when the chromosomes line up
3. cell division process for simple organisms

multiple choice: choose the best answer

1. which of the following is not a main type of cell division?

a. mitosis
b. meiosis
c. interphase
d. binary fission

1. which step of mitosis is illustrated to the right?

a. prophase
b. metaphase
c. anaphase
d. telophase

1. what type of organisms mainly undergo binary fission?

a. humans
b. plants
c. animals
d. bacteria

1. how often do living organisms make new cells?

a. never
b. sometimes
c. frequently
d. constantly

1. which of the following is not a difference in mitosis and meiosis?

a. mitosis produces new cells, while meiosis does not
b. mitosis produces two daughter cells identical to the mother cell, while meiosis
produces four daughter cells.
c. cells produced during mitosis are known as diploids, while cells produced from
meiosis are called haploids.
d. chromosome numbers remain the same in mitosis, while they are reduced by
half in meiosis.

1. what mainly occurs during the telophase part of mitosis?

a. chromatin condenses into chromosomes.
b. chromosomes line up along the middle of the cell.
c. chromosomes separate and move to opposite sides of the cell.
d. the cell walls pinch off and split down the middle.

Explanation:

1. Mitosis, meiosis, and binary fission are cell - division types. Interphase is a stage in the cell cycle (not a division type).
2. In anaphase, chromosomes separate and move to opposite sides (matches the illustration concept).
3. Bacteria mainly use binary fission for reproduction.
4. Living organisms constantly make new cells (for growth, repair, etc.).
5. Both mitosis and meiosis produce new cells. Mitosis gives 2 diploid identical cells; meiosis gives 4 haploid non - identical cells with half the chromosome number.
6. In telophase, the cell walls pinch off and split (cytokinesis related).

Answer:

1. C. Interphase
2. C. Anaphase
3. D. Bacteria
4. D. Constantly
5. A. Mitosis produces new cells, while meiosis does not
6. D. The cell walls pinch off and split down the middle
