Lec 5- Eukaryotic Life Cycles

Question 1

Ploidy

Answer 1

refers to the number of sets of
chromosomes you have

Question 2

haploid

Answer 2

An egg has 1 complete set of
chromosomes

Question 3

Haploid

Answer 3

A sperm has 1 complete set of
chromosomes

Question 4

Gamete

Answer 4

haploid cell that fuses with another haploid cell during
fertilization as part of sexual reproduction

Question 5

This process generates
diversity

Answer 5

the diploid
zygote has genome
made up of two sets of
chromosomes that
have never come
together before

Question 6

Fertilization

Answer 6

two gametes fuse
The haploid (n) nuclei fuse
The new zygote has two complete sets of chromosomes = Diploid (2n)

Question 7

Two kinds of eukaryote cell division

Answer 7

Mitosis
- meiosis

Question 8

process of mitosis

Answer 8

Need to get from being single-celled to multi-celled. That
process is
-Creates genetically identical cells

Question 9

mitosis

Answer 9

Chromosomes are duplicated, then the cell
divides into two new cells
* One of the copies of the chromosomes
goes into each new cell

Question 10

process of meiosis

Answer 10

To sexually reproduce, must make eggs/sperm that only have one set of
chromosomes, so can join and get back to correct number
-Creates haploid cells

Question 11

meiosis

Answer 11

Produces 4 non-identical
daughter cells
* Diploid (2n) cells undergo to
produce haploid (n) cells
* Duplicate chromosomes, then
divide cells and chromosomes
2x
* Makes haploid gametes that
later fuse to make a diploid
zygote
* For sexual reproduction only
