10.5 M phase Flashcards
which 2 phases make up the M-phase
mitosis and cytokinesis
5 phases of mitosis
1 prophase 2 prometaphase 3 metaphase 4 anaphase 5 telophase
phase where the spindle apparatus forms and the nuclear envelope breaks down
prophase
bridge of microtubules
spindle apparatus
radial array of microtubules extended toward the plasma membrane
asters
difference between prophase in animal and plant cells
spindle apparatus does not form in plant cells and they have no centrioles or asters
after the nuclear envelope breaks down it is reabsorbed by the
endoplasmic reticulum
chromosomes attach to the spindle apparatus during
prometaphase
phase where the chromosomes align at the equator
metaphase
imaginary plane perpendicular to the axis of the spindle that passes through the circle of chromosomes
metaphase plate
sister chromatids are pulled apart during which phase
anaphase
kinetochores are pulled toward the poles during anaphase _
A
the poles move apart during anaphase _
B
phase in which the spindle apparatus breaks down and the nuclear envelope reforms
telophase
phase where the cell divides
cytokinesis
