somatic cell division
|
The growth and repair of cells(mitosis)
|
|
|
|
germ cell division
|
The form of sexual reproduction(meiosis)
|
sex
|
|
|
chromatin
|
long, thin form of DNA, appears in interphase
|
|
|
|
chromosomes
|
There are 46 chromosomes in every cell, they are thread like strands of DNA, are not visible during interphase and appear in Prophase
|
Every Human has Chromosomes
|
|
|
homologues chromosomes
|
In diploid organisms, there are 23 pairs, members of each pair of defined as homologues. They are then copied in interphase 1 and will consist of identical sister chromatids
|
meiosis first stage
|
|
|
Tetrads
|
a foursome created of identical sister chromosomes joined with there homologues.
|
|
|
|
Centrosomes
|
an organelle involved in the organization of protein fibers to form the mitotic spindle
|
something to organize .... to create.....
|
|
|
centrioles
|
In animals a pair is located at the center of the centrosome to help create the mitotic spindle
|
Centrosome
|
|
|
mitotic nuclear spindle
|
a structure composed of protein fibers called microtubules. involved in the process of seperating chromosomes
|
Centrosome creates this
|
|
|
synapsis
|
When homologues chromosomes pair precisely align gene by gene along their lengths
|
homologues chromosomes
|
|
|
Interphase
|
Consists of 3 stages . G1- growth, normal cell activity. cell will acumilate materials needed for DNA. S-DNA replication occurs. G2-growth, proteins needed for cell division are made.
|
3 steps in interphase
|
|
|
meiosis in plant cells
|
there is a cell membrane that allows the cell to divide
|
|
|
|
meiosis in animal cells
|
the cell creats a contractile ring that allows for a cleavage furrow to form and seperate the cell
|
|
|
|
Benign Tumors
|
tumors that are not cancerous, tge cells in a benign , tumor do not spread to other parts of the body
|
|
|
|
malignant tumors
|
are cancerous, grow out of control and will spread to other parts of the body
|
