Cell cycle and cell division Flashcards
cycle of cell’s growth, development and division
cell cycle
part of the cell cycle when the cell grows and develops
interphase
three stages of interphase
G1, S, G2
phase of rapid growth and organelles replicate
G1
DNA replicates
S
cell prepares for cell division
G2
two MAIN phases of the cell cycle
interphase and mitotic phase
two stages of mitotic phase
mitosis and cytokinesis
when a cell’s nucleus divides
mitosis
when a cell’s cytoplasm divides
cytokinesis
four stages of mitosis
prophase, metaphase, anaphase, telophase
three things that happen during prophase
DNA condenses into chromosomes; nuclear membrane breaks down; spindle forms
what happens during metaphase
chromosomes line up along the center of the cell
three things that happen during anaphase
sister chromatids separate; spindle fibers shorten; cell gets longer
four things that happen during telophase
nuclear membrane forms; chromosomes unwind; spindle breaks down; two identical nuclei form
long, thin strands of DNA
chromatin
identical, make up two halves of a duplicated chromosome
sister chromatids
holds sister chromatids together
centromere
the two new cells formed by mitosis and cytokinesis
daughter cells
fibers create a furrow in the middle of a cell - this happens in ___ cells
animal cells
vesicles form the cell plate, which grows into a new cell wall - this happens in ___ cells
plant cells
four reasons why a cell might divide
reproduction, growth, replacement, repair
what is the longest phase of the cell cycle?
interphase, specifically G1
