i think it has something to do with the distribution of genes that will be inherited soon by the offspring. interphase is responsible for the creation/production of organelles and it is where DNA was synthesized. it was followed by mitotic division, which is the duplication of genes with the same number of chromosomes. then meoitic division will carry the genes but divide the chromosomes to half so that during fertilization it will restore the original number of chromosomes.

What is critical in the cell cycle because it indicates the cell is ready for division?
The Synthetic Phase, also called the S Phase, is critical in the cell cycle because it helps the cell indicate that it is ready for division. During this phase, the DNA within the cell is also copied during this process.
What happens to water in each stage of the cycle?
Water gets converted into different state. It is done at each stage.
What are the three stages of the cell cycle of a eukaryotic cell?
First stage - The cell grows and copies its organelles and chromosomes. During this time, the strands of DNA and proteins are like loosely coiled pieces of thread. After each chromosome is duplicated, the two copies are called chromatids. Chromatids are held together at a region called the centromere. The chromatids each twist and coil and condense into an X shape. After this happens, the cell enters the second stage of the cell cycle. Second Stage - The chromatids separate. The complicated process of chromosone is separation is mitosis. Mitosis ensures that each new cell receives a copy of each chromosomes. Mitosis can be divided into four phases. Third Stage - The cell divides and produces two cells that are identical to the original cell. Cell division will be discussed after mitosis has been described.
What happens in the cell cycle?
During the cell cycle, a cell grows prepares for division & divides to form two daughter cells, each of which then begins the cell cycle all over again.
What might happen to a new cell if it didn't have the same amount of chromosomes as the original cell?
Then it's a prokaryote cell (such as bacteria). If not a prokaryote then it just wouldn't be a cell because with eukaryote cells, if there are no chromosomes, there is no cell or life with that cell.
After which stage in the cell cycle is each new cell an exact copy of the parent cell?
interphase
What happens in the first stage of the cell cycle in a eukaryotic cell?
In the first stage, called interphase, the cell grows and copies its organelles and chromosomes. After each chromosomes is duplicated, the two copies are called chromatids.

In the first stage, called interphase, the cell grows and copies its organelles and chromosomes. After each chromosomes is duplicated, the two copies are called chromatids.
What do mitosis and cytokinesis produce?
Each cycle of mitosis produces 2 daughter cells from 1 parent cell. Cytokinesis is the final stage in each cycle, where a cleavage burrow is formed and the cell splits into two identical daughter cells.
Chromosomes are only present in the cell cycle during?
Chromosomes can be seen during cell divison, Reference Before a cell gets ready to divide by mitosis, each chromosome is duplicated (during S phase of the cell cycle
What happens to the chromosomes during the stage cycle when the nucleus divides?
The Chromosomes separate from each other and move to opposite ends of the cell.
What is the stage of cell cycle during which the cell's nucleus divides into two nuclei and one copy of the DNA is distributed into each daughter cell?
For a body cell it is called mitosis and for a sex cell it is called meiosis
What stage does the nuclear envelope reform around the chromosomes?
In the cell cycle, the nuclear envelope reforms around each cluster of chromosomes in telophase.
Does a cell make a copy of its DNA during the stage of the cell cycle called mitosis?
No. Mitosis is strictly the stage of the cell cycle where the chromatin condenses into chromosomes, the nuclear envelope dissolves, the chromosomes line up on the metaphase plate, spindly fibers attach to the kinetochores of each chromosome and "pull" sister chromatids apart to opposite poles of the cell. Then the cell pinches off and forms a nuclear envelope around the DNA. The stage in the cell cycle where a cell duplicates its genetic material is called the S phase, preceded by the G1 phase, followed by the G2 phase, then mitosis and cytokinesis.

Which stage of cell cycle varies most in length?
There isn't a way (yet) to defined the lengths of stages in the cell cycle. One reason is because the cell cycle makes several stops/checkpoints. The G2 stage has a checkpoint/stop if DNA has not finished replicating and this will prevent the start of the M stage before completion of the S stage. Another cell cycle checkpoint occurs during the M (mitotic) stage. The cell cycle stops if the chromosomes are not going to be distributed correctly to the daughter cells. Damage to the DNA can also stop the cell cycle at the G1 stage and if damage is found then DNA repairs will start but if any kind of problem is not possible to fix than cell will automatically begin apoptosis "a.k.a. cell suicide". For adult mammalian cells, interphase "which includes three stages G1, S, and G2" lasts for about 20 hours and accounts for 90% of the cell cycle and yet embryonic cells can complete the entire cell cycle in just a few hours..
