representation of cell division

division of nucleus called mitosis

division of cytoplasm called cytokinesis

M phase is very short in comparison to the larger time that cell is undergoing the interphase.

final step of the M phase is cytokinesis, the division of cytoplasm

cell division occurs through two processes: mitosis, when the nucleus divides, and cytokinesis, when the cytoplasm divides.

The M phase of the cell cycle always results in two daughter cells.

is division of the cytoplasm.

The M phase is complete after cytokinesis occurs.

Both of these daughter cells are identical to each other and identical to the original cell that underwent mitosis

final stage of mitosis

a nuclear membrane re-forms around each set of chromosomes.

Then the chromosomes spread out into chromatin, and the nucleolus becomes visible once again.

Mitosis, the division of the nucleus, is now complete.

the nucleolus and nuclear membrane re-form. The chromosomes disperse into chromatin.

during anaphase, spindle fibers separate the sister chromatids at their centromeres

once separated from each other, each chromatid is called chromosome

remember that centrioles are at the poles and looks like french fries

where the plane of cleavage is set to the right angle to the mitotic spindles.

the spindle fibers separate sister chromatids into two separate groups of chromosomes, pulling them toward the poles.

the centrioles complete their movement to the poles of the cell while the spindle fibers line up the chromosomes along the equator of the cell

before metaphase happen... chromosomes are no longer separated from the cytoplasm the opposite ends of the spindle fibers can attach to the centrioles.

the equilibrium ''central'' positioning of the chromosomes means that one sister chromatids has a an attached spindle fiber on one chromosomes and the other sister chromatid is attached to the other centrosome.

spindle fibers align the chromosomes along the cell equator.

longest phase in Mitosis

chromatin begin to continue into the shape of chromosomes and nucleolus disappears

when the spindle fiber elongate as the centrioles begin moving to opposite side or poles nuclear membrane surrounding the nucleus disappears

centromere - attaches the sister chromatids together

cytoplasm microtubules known as spindle fibers begin to fan out form two sets of paired structures called centrioles.

chromatin condenses into chromosomes, spindle fibers form, and the nucleolus and nuclear membrane disappear.
