Question

directions: when you compare and contrast two processes, you tell how they are alike and different. compare and contrast mitosis and meiosis.

1. mitosis and meiosis

a. how are they alike?
b. how are they different?

directions: write a for advantage or d for disadvantage to tell about sexual and asexual reproduction.
asexual reproduction

1. ___ can reproduce alone
2. ___ offspring are exact copies
3. ___ can reproduce quickly

sexual reproduction

1. ___ must find a mate
2. ___ diversity
3. ___ takes longer to reproduce

directions: write asexual, sexual, or both to identify the kind of reproduction associated with each word or phrase.

1. nucleus
2. exact copy
3. two parents
4. diversity
5. gametes
6. one parent
7. mitosis
8. meiosis

Explanation:

1A. Both mitosis and meiosis are cell - division processes. They involve chromosome duplication and separation. They also occur in eukaryotic cells.
1B. Mitosis results in two genetically identical diploid daughter cells and is for growth, repair, and asexual reproduction. Meiosis results in four genetically diverse haploid daughter cells and is for sexual reproduction.

1. a (advantage of asexual reproduction as an organism can reproduce alone).
2. a (advantage as offspring are exact copies in asexual reproduction).
3. a (advantage as asexual reproduction can be quick).
4. d (disadvantage as sexual reproduction requires finding a mate).
5. a (advantage as sexual reproduction leads to genetic diversity).
6. d (disadvantage as sexual reproduction takes longer).
7. both (nucleus is involved in both asexual and sexual reproduction processes).
8. asexual (exact copies are produced in asexual reproduction).
9. sexual (sexual reproduction involves two parents).
10. sexual (genetic diversity is a characteristic of sexual reproduction).
11. sexual (gametes are involved in sexual reproduction).
12. asexual (asexual reproduction has one parent).
13. asexual (mitosis is involved in asexual reproduction).
14. sexual (meiosis is involved in sexual reproduction).

Answer:

1A. Both are cell - division processes in eukaryotes involving chromosome duplication and separation.
1B. Mitosis: two identical diploid cells, for growth/repair/asexual reproduction. Meiosis: four diverse haploid cells, for sexual reproduction.
