Interphase
Interphase is the part of the cell cycle during which a cell is not dividing. Much activity takes place in this phase of the cell's life. During interphase, the cell grows to about twicethe size it was when it was first produced. The cell also engages in normal life activities, such as transporting materials in and transporting wastes out. Also, cellular respiration occurs, whichprovides the energy the cell needs.
Changes that occur during interphase prepare a cell for division. Before a cell can divide, it duplicates its DNA exactly. Correct copying of the DNA is veryimportant. It ensures that, after cell division, each new cell gets a complete set of DNA.
What cell processes occur during interphase?
Cell Division Phase
Mitosis is the part of the cellcycle during which the nucleus divides. Prokaryotes do not undergo mitosis because they have no nucleus. In most cells, mitosis is the shortest period in the life cycle. The function of mitosis is tomove the DNA and other material in the parent cell into position for cell division. When the cell divides, each new cell gets a full set of DNA and other cell structures. Cytokinesis(SY-toh-kuh-NEE-sihs) is the division of the parent cell's cytoplasm. Cytokinesis occurs immediately after mitosis.

VOCABULARY
Make a frame game diagram for interphase.
Thearrows in the Cell Cycle diagram represent the passage of time. Interphase is in red, mitosis is in purple, and cytokinesis is in yellow.
As a result of mitosis and cytokinesis, the original—orparent—cell splits into two genetically identical daughter cells. In this case, the term daughter cell does not imply gender. It is a term scientists use to refer to these new cells. Each daughter cellreceives a complete set of DNA from the parent cell.
Cell division produces two genetically identical cells.
Recall that many cells in your body are continually dividing into new cells. The new...
