What is Cell Division?
Process where a single cell divides into two identical daughter cells.
What is cell division essential for?
Growth repair reproduction
what are the three processes that are involved in cellular division?
interphase, mitosis, cytokinesis
what are the phases of interphase
g1, s, g2
what are the phases of mitosis in order
prophase metaphase anaphase telophase
why is cell division important for growth?
allows organism to grow from a single cell ti a complex multi cellular organism
how is cell division involved in repair?
replaces the damaged or dead cells
mitosis is the division of the _______
nucleus
true or false: cytokinesis is the final step of mitosis
false- final step of cellular division
which phase in interphase is the dna replication into two sets of dna
s phase
spindle fibers form in?
prophase
at what structure to spindle fibers attach to
centromeres of the chromosomes
at what phase are sister chromatids present?
anaphase
chromatids become chromatin through______ at the _____ phase
unwinding or uncoiling in telophase
true or false:two nucleuses can be seen in metaphase
false in telophase
how does cytokinesis occur in animals?
cell membrane pinches inward.
what is the purpose of cytokinesis
completes cell division by separating the cytoplasme
cell plate forms in what phase and in what cell type
cytokinesis in plant cells
what is the relationship between the two daughter cells?
structures made of dna carrying genetic information is called
chromosomes
at what step does the dna first become visible
prophase
uncoiled dna present in the nucleus is called
chromatin
how many cells are present in telophase
1
what is the structure that is responsible for moving dna around in mitosis
spindle fibers
nucleus disappears in ________ and ___ nucleus appear in ______
