MITOSIS• In mitosis the nucleus and it’s contents divides.• The phases of mitosis are: prophase, metaphase, anaphase and telophase.• When the cell is not on the process of mitosis it is on interphase

INTERPHASE• Is the phase on the cell cycle where the cell spends most of it’s life• Is the 'daily living' or metabolic phase of the cell, in which the cell obtains nutrients and metabolizes them, grows, reads its DNA, and conducts other \"normal\" cell functions.

PROPHASE• In prophase copied DNA condenses into chromosomes.• The nucleus disappears, and the nuclear membrane breaks down.• Spindle finer begin to form.• The copied chromatin coils together tightly. The coils from visible duplicated chromosomes. The nucleus disappears, and the nuclear membrane breaks down. Structure called spindle fibers form in the cytoplasm.

METAPHASE• In metaphase chromosomes line up in a single file at the middle of the cell.• The spindle fibers pull and push the duplicated chromosomes to the middle of the cells. This arrangement ensures that each new cell will receive one copy of each chromosomes. Metaphase is the shortest phase in mitosis, but it must be completed successfully for the new cells to be identical.

ANAPHASE• In anaphase sister chromatids separate.• Spindle fibers begin to shorter, pulling chromatids toward opposite sides of the cell.• The cell begins to lengthen.• The third stage of mitosis happens, the two sister chromatids in each chromosomes separate from each other. The spindle fibers pull them in opposite directions. Once separated, the chromatids are now two identical single-stranded chromosomes. As they move to opposite sides of a cell, the cell begins to get longer. Anaphase is done when two identical sets of chromosomes are at opposite ends of a cell.

TELOPHASE• In telophase a nuclear membrane forms around the chromatin.• Chromosomes begin to unwind.• Spindle fibers begin to break down.• Two identical nuclei form.• The spindle fiber began to disappear. Also, the chromosome begin to uncoil. A nuclear membrane forms around each set of the cell. This forms two new identical nuclei. Telophase is the final stage of mitosis. It is often described as the reverse of prophase because many of the processes that occur during prophase are reversed during telophase

CYTOKINESIS• In cytokinesis the cytoplasm and its content divides• which divides the cytoplasm of a parental cell into two daughter cells• It occurs concurrently with two types of nuclear division called mitosis and meiosis, which occur in animal cells.

RESULT OFTHE PROCESS• The result is two genetically identical daughter nuclei. The cell may then divide by cytokinesis to produce two daughter cells.

IMPORTANCE TOALL LIVINGORGANISM• All living organisms are important since we get most of our food, drinks, clothes, items of 2nd necessarity and more. And without any of them we would not be alive
