2 Roles of Cell Division - reproduction and replace old dead cells
Why do most cell divisions result in genetically identical daughter cells? - the DNA gets copied
What happens in G1 and G2? - growth
What happens in the S phase? - the DNA replicates
What happens in M phase? - cell division/cytokinesis
Which step(s) happen(s) in telophase or later? - Nuclear membrane forms and cytoplasm divides
Which step(s) happen(s) in prophase or earlier? - 2 centrosomes form and spindle begins to form
Which step(s) happen(s) in prometaphase? - Nuclear membrane disappears and chromosomes
attach to spindle
Which step(s) happen(s) in metaphase? - Chromosomes line up at middle of cell
Which step(s) happen(s) in anaphase? - Sister chromatids get pulled apart
Steps of Mitosis (in order) - 1.) 2 centrosomes form
2.)spindle begins to form
3.)nuclear membrane disappears
4.) chromosomes attach to spindle
5.)chromosomes line up at middle of cell
6.)sister chromatids get pulled apart
7.)nuclear membrane forms
8.)cytoplasm divides
, Main advantage of sexual reproduction - Increase genetic variability
Give on example of asexual reproduction - Budding
Difference between sexual and asexual reproduction - Sexual- involves both meiosis and fertilization
Asexual-doesn't involve meiosis and fertilization
What is fertilization? - when and egg and sperm(pollen) form together to make a zygote
What is the role of fertilization in alteration of generations? - It changes n to 2n
What is the role of meiosis with respect to fertilization? - To reduce chromosomes and to make sex
cells for fertilization
What is the main purpose of meiosis I? - To reduce the number of chromosomes
Why is meiosis I important in sexual reproduction? - It helps with genetic variability
What is the main purpose of meiosis II? - to separate the sister chromatids
What is the difference in the results of mitosis and the results of meisosis? - Mitosis- ends with two
cells
Meiosis-ends with 4 cells
What are gametes? - Sex cells
Are gametes diploid or haploid? Why is it important? - Usually haploid, they help with the number of
chromosomes not changing from generation to generation
In the context of meiosis, what is synapsis and why is it important in the process? - When two
homologous chromosomes pair up
