plant cellular reproduction
G1
growth 1
or
gap 1
- this happens immediately after a cell divides
the cell 'grows up' and grows in size
S
synthesis
phase
this is when DNA replicates
G2
growth 2
or
gap 2
- getting ready for mitosis
this is when the organelles divide
microtubules and other substances are made
chromosomes
begin coiling
prophase
this is the longest part of the process
starts when the
pre-prophase band
of microtubules/filaments forms. these become
spindle fibers
chromosomes bundle up
spindle fibers
attached themselves to two 'poles' within the cell
the nucleus dissolves into the cytoplasm
metaphase
chromosomes arrange themselves within the cage of the spindle fibers
the centromeres separate in half
anaphase
chromosome pairs get separated and pulled to the 'poles' of the cell by the spindle fibers
the chromosomes begin to unwind
telophase
a new nuclear envelope gets made around the daughter chromosomes, which then finish uncoiling
nucleoli reappear
a new cell wall gets made as the spindles break down and are replaced by
phragmoplasts
:arrow_left: interphase
mitosis :arrow_right:
:warning:
cytokinesis
vs
mitosis
technically, cytokinesis = the division of the
cell
and mitosis = the division of the
nucleus
1
: telomere
2
: centromere (
kinetochores
are here)
3
: chromatid (short arm)
4
: chromatid (long arm)
