Answer 17

sex and reproduction

Question 18

What is fundamental to life?

Answer 18

cell division

Question 19

Describe mitosis

Answer 19

replication
Chromosome # stays the same
retains ploidy - 2n - 2n or n-n
growth

Question 20

describe meiosis

Answer 20

halfling the amount of genetic info
# of chromosomes reduced to half 2n-n

Question 21

Reproduction VS sex

Answer 21

reproduction - multiplication
sex- recombination of genetic material between more than one - creates evolution - but not essential for it

Question 22

Why sex in eukaryotic cells?

Answer 22

• puts beneficial genes that arise in different individuals together in the same individual

Isogamy
Anisogamy
Plasmogamy
karyogamy

Question 24

describe syngamy

Answer 24

• fusion of haploid cells - n

Question 25

describe Isogamy

Answer 25

fusion of 2 morphologically similar n cells
- happens in many fungi and algae

Question 26

anisogamy

Answer 26

fusion of morphologically dissimilar cells
- oogamy - female is immobile, male is motile
