productiion of sex cells
cell division is neccessary 4?
1. growth/development
2. repalcement of dead/worn out/damaged tissue.
3. reproduction
cells that cant divide
red blood cells, muscles, nerve, liver
DNA
hereditary material
chromosome
DNA and its associated proteins condenses
chromatid
one of 2 attached copies of a chromosome
centromere
area of chromatid-attachment
kenetic chore
area around centromere; spindle attachment
diploid
full set of chromosomes; chromosomes exist in pairs
haploid
half the original # of chromosomes, exist individually
somatic cells
diploid cells that make up most organs & tissue of the body will undergo mitosis
germ cells
diploid cells that are boated in gonads; will undergo meiosis 2 produce haploid sex cells
gonads
location of germ cells(testies/ovaries)
how do we maintain chromsomal numbers in sexual reproduction?
Meiosis
