Interphase- The cell grows and matures in size. It prepare to split into two daughter cells by making a copy of it's DNA. The centrioles are also copied.
Prophase- This is the first stage of mitosis. The chromatin in the nucleus condenses to form chromosomes. The centrioles move to opposite ends of the cell. Spindle fiber form a bridge between the centrioles. And then the nuclear membrane breaks down.
Metaphase- The chromosomes line up in the middle of the cell, attaching to the spindle fibers with their centromere.
Anaphase- The centromeres split and the chromatids separate. The chromosomes are pulled to opposite ends of the cell by the spindle fibers. The cell stretches out as the chromatids are pulled to the ends.
Telophase- This is the last stage of mitosis. The chromosomes stretch out and lose their rod-like appearance. A nuclear membrane forms around each region of chromosomes. The DNA is then separated from the cytoplasm by a membrane.
Cytokinesis- The cell membrane pinches in around the center of the cell. Each daughter cell ends up with an identical set of chromosomes and about half of the organelles.

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 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 are all of the parts of cellular respiration?
The three parts of cellular respiration are: 1-Glycolysis (happens in the cytoplasm) 2-Krebs Cycle (Happens in the mitochondria) 3-Electron Transport Chain (happens in the mitochondria)
How many chromosomes are present in a mosquito cell at each what stages Meiosis?
6
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 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 happens at each checkpoint during the cell cycle?
Check for large healthy cell, proper DNA replication, and nuclear cytoplasmic division.
What occurs in each 3 main stages of cell cycle?
The three main stages of cell cycle are interphase, mitosis and cytokinensis.Interphase is made up of three stages - G1, S, and G2G1 phase - The first phase of the cell cycleThe cell prepares itself for the synthesis stage of the cell cycle. The cell checks to see if it has all materials required for synthesis.S phase - the DNA is copied so that at the end of this cycle each daughter cell has a complete set of chromosomes.G2 phase - The second growth phase of the cell cycleIn this phase the cell prepares itself for physical separation of the cell to form two daughter cells.MitosisIn this phase the pairs of chromosomes attach themselves to fibers that pull the sister chromatids to the opposite sides of the cell.CytokinensisThe cytoplasm then divides into two forming two daughter cells.
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 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.

How do the stages in the cell cycle work?
The first step in interphase. It is when the cell grows to it mature size.The cell make enough oragelles for the daugter cell.Then mitosis occures in the nulceas metephase it when chorasome form an x shape then form a line next anaphase and when is when the chorosomes pull away so the next is telophase is when two nuclei. The final step of cell cycle is cytokenis is when two new daugter cell are form

Stages through which a plant or animal goes in its life?
The stages through which a plant or animal goes through in life is called the life cycle. Each plant or animal species has a different life cycle.
