positioned for
duplication. Where in Anaphase ll, chromosomes split and move to opposite
sides of the cell. Each one split into two pieces, they do not divide DNA
between new cells; only splitting DNA that exists. Daughter cells will get
one-half of DNA needed to make a functioning cell. Telophase ll, DNA is
completely pulled to the sides and cell membrane begins to pinch. When this
ends you are left with four haploid cells. The four haploid cells are
called gametes. Gametes find other gametes they can combine with. When they
combine they produce a new organism.
Mitosis is the process when the cell nucleus divides making two new nuclei.
All cells need to duplicate. Mitosis is a simple duplication of a cell.
Both of the new daughter cells have the same pieces and genetic code. Two
copies made from one original. There are five stages to a cells life cycle.
Prophase: time for a cell to divide it has to get everything ready. It
duplicates DNA, positions the centrioles ready for mitotic division.
Metaphase: DNA assembles on the central axis of the cell, centrioles attach
to DNA using tubules. DNA is condensed into chromosomes. Two strands of
chromosome connect at the centre by centromere. Tubules from the centrioles
are connected to the centromere not the DNA.
Anaphase: Separation begins. Choromosome split forming two separate pairs
of strands, each are pulled to opposite sides of the cell. Chromatics split
Telophase: cell division is almost complete. The cell membrane closes in
and splits the cell into two. Making two new cells.
Interphase: The cell is in a normal state, resting and collecting nutrients
and energy needed. The cell is getting ready for another division.
Cell will duplicate its nucleic acids, ensuring all the pieces are in
place and ready for the cell division.

plant. A seed is comprised of mu...
