Cell Function Flashcards
describe all chemical reaction involved in maintaining the living state of the cells and organism
Metabolism
breakdown of molecules
catabolism
sythesis of all compounds
anabolism
cyclical process of growth and division
cell cycle
preparatory stage for mitosis
interphase
nucleus is clear visible and chromosomes appear irregular granular
Interphase
cell maitains homeostasis
building of new protoplasm and organelles
G1
DNA molecule is copied and replicates
S
certain proteins and RNA molecules needed to reenter for the next cell division
G2
somatic cell division producing two daughter cells
mitosis
sex cell division, producing four daughter cells with haploid chromosomes
Meiosis ( Reduction division)
one parent cell divide to form two daughter cell
mitosis
chromosomes enlarge
nuclear membrane disppears
cetrioles migrate to opposite poles
Prophase
chromosomes line to the center of the cell attached to its centromere
metaphase
duplicate centromere migrate in opposite direction
Anaphase
