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
chromosomes reached the opposite poles
chromosomes begin to become longer, thinner and distinct
Telophase
two succesive division resulting in the formation 4 grand daughter cells each containing23 chromosomes
Meiosis
process that results in an increase of the number of cells, and is defined by the balance between cell divisions.
Cell proliferation
during anaphase, spindles attached to _______ begin to shorten
kinetochores
reached completion of cell division
cytokinesis
the resting “ resting stage” or non-mitotic portion o cell cycle
interphase
