meiosis

Question 1

what is meiosis?

Answer 1

a type of cell division which results in the production of haploid gametes

Question 2

where does meiosis occur?

Answer 2

in sexual tissues of an organism

Question 3

how many times does a diploid cell divide?

Answer 3

twice

Question 4

how many cells does meiosis create?

Answer 4

4

Question 5

are the cells haploid or diploid?

Answer 5

haploid

Question 6

what are the cells called?

Answer 6

gametes

Question 7

what are the gametes in humans?

Answer 7

the egg and the sperm

Question 8

what must happen before any type of cell division?

Answer 8

the DNA must copy itself

Question 9

what does this replication do?

Answer 9

doubles the amount of DNA and creates the characteristic X shaped chromosomes

Question 10

what does the parent cell then do?

Answer 10

divides once to half the number of chromosomes into two cells

Question 11

what happens in the second division?

Answer 11

each X shaped chromosome in the two cells is split down the middle so that each half is pulled to each pole of the cell

Question 12

how many cells are produced?

Answer 12

4 genetically different haploid daughter cells

Question 13

differences between mitosis and meiosis: (cells)?

Answer 13

mitosis- two daughter cells produced
meiosis- 4 daughter cells produced

Question 14

differences between mitosis and meiosis: (diploid/haploid)?

Answer 14

mitosis- daughter cells are diploid
meiosis- daughter cells are haploid

Question 15

differences between mitosis and meiosis: (identical)?

Answer 15

mitosis- daughter cells are genetically identical
meiosis- daughter cells are genetically different

Question 16

differences between mitosis and meiosis: divisions?

Answer 16

mitosis- one division occurs
meiosis- two divisions occurs
