|
what is the purpose of the cell cycle and mitosis |
regeneration of cells |
|
|
Which cells do mitosis take place in, name at least three specific cells |
Everything but the sex cells; lung, skin, heart |
|
|
Define haploid and give the letter that represents it |
"n" a cell with each kind of chromosomes, 23, half the number of body cells. Known as gametes |
|
|
Define diploid and give the number and letter that represents it |
"n2" a cell with of of each chromosomes 23 mom 23 dad 46 all together
|
|
|
which process goes from diploid to diploid |
mitosis |
|
|
which process goes from diploid to haploid |
meiosis |
|
|
what does diploid to haploid mean |
half the number of chromosomes |
|
|
what does diploid to diploid mean |
the daughter cell will have the same number of chromosomes as the parents |
|
|
how many divisions does mitosis go through |
one |
|
|
how many divisions does meiosis go through? why is this important? |
two |
|
|
Why are the divisions different for both processes? |
? |
|
|
What is the purpose of meiosis and which type of cells does it take place in? |
Happens in sex cells, purpose is to reproduce and create genetic diversity |
|
|
Why is the process of crossing-over in meiosis so important to a species? |
the mixing of chromosomes can create a better species
|
|
|
Explain independent assortment and tell why it is important? |
genes are passed separately and can occur in different combos, example not all people with brown eyes will have brown hair.
it is important because it creates new genetic combos |
|
|
What is a cell called after the sperm fertilizes the egg? |
zygote |
|
|
Once the egg is fertilized do the two new cells go through mitosis or meiosis? (explain) |
mitosis, because it already has 23 chromosomes from each the sperm and egg, so now it starts reproduces itself exactly |
|
|
which process starts with 46 chromosomes and ends up with 46 chromosomes? |
mitosis |
|
|
which process starts with 46 chromosomes and ends up with 23 chromosomes? |
meiosis |
