Mitosis/Meiosis How are they different?

1. Mitosis/MeiosisHow are they different?

2. Crossing over The exchange of DNA between the chromatid arms on homologous pairs is called ________________ This type of cell division used by bacteria to reproduce Binary fission

3. The mixing up of maternal and paternal chromosomes as they move apart during anaphase I is called ______________ Independent assortment The pairing up of homologous chromosomes during prophase I is called _________________ synapsis

4. Crossing over This diagram is showing _________________ During which phase does this happen? PROPHASE I of meiosis

5. Makes 2 daughter cells ______________ Makes haploid cells _______________ Divides twice but copies DNA once __________________ Used to repair injuries ______________ mitosis Is it MITOSIS or MEIOSIS? meiosis meiosis mitosis

6. Makes 4 daughter cells ______________ Makes diploid cells _______________ Copies DNA every __________________ time it divides Used to make gametes ______________ Meiosis Is it MITOSIS or MEIOSIS? mitosis mitosis meiosis

7. Makes 2n cells ______________ Crossing over happens _______________ Used when organisms __________________ grow bigger Used in sexual reproduction ___________ mitosis Is it MITOSIS or MEIOSIS? meiosis mitosis meiosis

8. Testes and ovaries do it ____________ Body cells do it _______________ Crossing over happens ____________ Divides twice ______________ in a row meiosis Is it MITOSIS or MEIOSIS? mitosis meiosis meiosis

9. Independent assortment_____________ happens Divides just once_______________ Used in oogenesis __________________ Makes cells identical to parent cell __________________ meiosis Is it MITOSIS or MEIOSIS? mitosis meiosis mitosis

10. Makes 2 daughter cells ______________ Makes haploid cells _______________ Divides twice but copies DNA once __________________ Used to repair injuries ______________ mitosis Is it MITOSIS or MEIOSIS? meiosis meiosis mitosis

11. Type of cell division shown meiosis Body organ where you would expect to see the above happen Ovary or testes

12. Type of cell division shown mitosis Tell one reason why a cell would do this Grow organism bigger Repair injuries Replace worn out cells

13. Polar bodies The small cells produced when the cytoplasm divides unevenly during oogenesis are called ______________ Producing offspring without using sperm or eggs in which the DNA comes from only 1 parent Asexual reproduction

14. TRUE or FALSE Polar bodies will go on to become mature eggs FALSE; they will die The production of mature sperm is called ___________________ spermatogenesis

15. Type of reproduction in which offspring are produced by combining the genetic material from 2 parents A cell with only one copy of each chromosome is called ___________ Sexual reproduction Haploid OR 1n

16. diploid OR 2n A cell which has 2 copies of every chromosome is called _____________ Type of division that makes daughtercells which are different from the parent cell and different from each other meiosis

17. oogenesis The production of a mature egg is called ____________________ Phase in which INDEPENDENT ASSORTMENT happens Anaphase I

18. Name 2 ways the DNA in cells getsrecombined in new ways during meiosis Crossing over OR independent assortment Phase during which SYNAPSIS happens Prophase I

19. 4 Spermatogenesis produces ____ mature sperm cells Phase in which CROSSING OVER happens Prophase I

20. How many mature eggs are produced during oogenesis? Only 1; the other 3 are polar bodies Tell one phase that is different inmeiosis than in mitosis Prophase I- Synapsis & crossing over Anaphase I- independent assortmentMetaphase I- pairs line up togetherInterphase II- No DNA is copied
