1. Mitosis & Meiosis SC.912.L.16.17

2. Which answer best compares the end result of a cell that goes through meiosis to that of a cell that goes through mitosis? A. The cell that goes through meiosis will have the same number of daughter cells as the one that goes through mitosis. B. The cell that goes through meiosis and the one that goes through mitosis will both produces haploid cells. C. The cell that goes through meiosis results in haploid cells, while the one that goes through mitosis produces diploid cells. D. The cell that goes through meiosis will produce half as many daughter cells as the one that goes through mitosis. C. The cell that goes through meiosis results in haploid cells, while the one that goes through mitosis produces diploid cells.

3. As with all organisms that reproduce by alternation of generations, Laminaria spends part of its life in a haploid form. In what form does it spend the remainder of its life? A. unicellular diploid forms B. unicellular haploid forms C. multicellular diploid forms D. multicellular haploid forms C. multicellular diploid forms

4. The diagrams show different stages of mitosis. Which of the following correctly puts them in the order in which they occur during mitosis? A. 2, 1, 3, 4 B. 3, 2, 1, 4 C. 1, 3, 2, 4 D. 2, 3, 1, 4 D. 2, 3, 1, 4 1 2 3 4

5. Which of the following describes processes that take place in both mitosis and meiosis? A. Chromosomes condense and coil up tightly. B. Chromosomes organize into homologous pairs. C. Chromosomes exchange pieces of their arms. D. Chromosomes migrate to haploid daughter cells. A. Chromosomes condense and coil up tightly.

6. In what way is crossing over during meiosis beneficial to sexually reproducing organisms? A. It makes it possible for cells to repair damage to their DNA. B. It allows organisms to switch sex when the sex ratio is out of balance. C. It increases the amount of genetic variability possible in their offspring. D. It decreases the chances that a mutation will be harmful to the offspring. C. It increases the amount of genetic variability possible in their offspring.

7. If a sexually reproducing organism has 23 pairs of chromosomes in its cells, what will it have in the sex cells it creates if they are produced without mistakes? A. It will have either the first 23 or last 23 chromosomes. B. It will have 23 complete pairs of chromosomes. C. It will have one chromosome from each of the 23 pairs. D. It will have a random collection of 23 of the chromosomes. C. It will have one chromosome from each of the 23 pairs.

8. Why do asexually reproducing organisms generally create offspring using mitosis instead of meiosis? A. Mitosis allows them to create more new genetic combinations in their offspring. B. Through mitosis, they can pass on their complete set of chromosomes to their offspring. C. Offspring produced through mitosis have fewer mutations, since fewer steps are involved. D. Using mitosis allows them to produce offspring with twice as many chromosomes as themselves. B. Through mitosis, they can pass on their complete set of chromosomes to their offspring.

9. If a cell is damaged in such a way that it cannot stop going through mitosis, what will be the likely result? A. The organism will grow larger. B. A cancerous tumor will form. C. The damaged cell will be repaired. D. A new, undamaged cell will replace it. B. A cancerous tumor will form.

10. Mitosis and meiosis are processes involved in cellular reproduction. Which of the following describes an event that results from mitosis but NOT meiosis? A. two stages of cell division B. replication of cellular genetic material C. daughter cells that are identical to the parent cell D. four daughter cells that are produced from each parent cell C. daughter cells that are identical to the parent cell

11. Sexual reproduction is advantageous in an evolutionary sense over asexual reproduction because it A.produces many cells B.produces genetic variation C.requires only one parent D.makes clones B. produces genetic variation

12. OUT OF 10 QUESTIONS 1/10 = 10% 2/10 = 20% 3/10 = 30% 4/10 = 40 % 5/50 = 50% 5/50 = 50% 6/10% = 60% 6/10% = 60% 7/10 = 70% 7/10 = 70% 8/10 = 80% 9/10 = 90% 10/10 = 100%
