Mitosis/Meiosis How are they different?

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

Independent assortment 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

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

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

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

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

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

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

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

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

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

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 Polar bodies Asexual reproduction

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

A cell with only one copy of each chromosome is called ___________ 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

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

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

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

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

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