mitosis Flashcards
mitosis
the process by which the nucleus of a cell divides while maintaining the chromosome number
asexual reproduction
reproduction with only one parent, offspring identical to the parent
sexual reproduction
a new individual is produced by the union of the nuclei of two specialized sex cells
chromatin
the material of which chromosomes are composed
chromosomes
rod like structures in cells that undergo division and that contain hereditary information of the organism
chromatids
one of the two strands of a doubled chromosome
karyokinesis
during cell division the process of partition of the cells nucleus into the daughter cells
cytokinesis
the division of the cytoplasm of the cell after mitosis, the cell divides into 2 parts, each containing one of the newly formed nuclei and half of the other contents of the parent cell
centrosome
a organelle that is the main place where cell microtubules are organized. it regulated the cell division cycle, the stages which lead up to the one organelle cell dividing into two
centromere
the region of attachment of two sister chromatids
centrioles
cylindrical organelles found near the nucleus in animal cells that are involved in mitosis
spindle fibers
involved in moving and segregating the chromosomes during nuclear division. made up of microtubules
asters
star shaped structures formed during mitosis in animal cells by fibers from the centrioles
cleavage furrow
the indentation of the cells surface that begins the progression of cleavage, by which animal cells undergo cytokinesis
cell plate
a structure formed during cytokinesis in a plant cell that divides the cell in half, forming part of the new cell walls of the daughter cells
