Mitosis is the process in which a eukaryotic cell nucleus splits in two, followed by division of the parent cell into two daughter cells. The word “mitosis” means “threads,” and it refers to the threadlike appearance of chromosomes as the cell prepares to divide.
What is the splitting of cells called?
Cytokinesis is the physical process of cell division, 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.
During what phase of mitosis does the cell split?
In anaphase, the sister chromatids separate from each other and are pulled towards opposite ends of the cell. The protein “glue” that holds the sister chromatids together is broken down, allowing them to separate. Each is now its own chromosome. The chromosomes of each pair are pulled towards opposite ends of the cell.
What happens when the cell splits?
When cells divide, they make new cells. A single cell divides to make two cells and these two cells then divide to make four cells, and so on. We call this process “cell division” and “cell reproduction,” because new cells are formed when old cells divide. The ability of cells to divide is unique for living organisms.
What is the function of mitosis in a cell that is about to divide?
During mitosis one cell? divides once to form two identical cells. The major purpose of mitosis is for growth and to replace worn out cells.
What is the difference between splitting cells and merging cells?
Splitting cells is similar to adding a row or column, but it all takes place in one cell instead of a group of cells. … Merging cells, however, is similar to deleting a cell and then adjoining it with a neighboring cell.
What happens during G2 phase?
During the G2 phase, extra protein is often synthesized, and the organelles multiply until there are enough for two cells. Other cell materials such as lipids for the membrane may also be produced. With all this activity, the cell often grows substantially during G2.
What happens in G2?
The last part of interphase is called the G2 phase. The cell has grown, DNA has been replicated, and now the cell is almost ready to divide. This last stage is all about prepping the cell for mitosis or meiosis. During G2, the cell has to grow some more and produce any molecules it still needs to divide.
What process follows mitosis?
Usually the cell will divide after mitosis in a process called cytokinesis in which the cytoplasm is divided and two daughter cells are formed.
What happens to the cell during mitosis?
During mitosis, a eukaryotic cell undergoes a carefully coordinated nuclear division that results in the formation of two genetically identical daughter cells. … Then, at a critical point during interphase (called the S phase), the cell duplicates its chromosomes and ensures its systems are ready for cell division.
When a cell divides what does each daughter cell receive?
In this form of cell division, a cell replicates its DNA, increases in size, and divides into two daughter cells. Each daughter cell receives on copy of the replicated parental DNA.
Is mitosis a reduction division?
Meiosis is called reductional division because number of chromosomes and amount of DNA in daughter cells is reduced to half than that of parent cell.

What is the function of mitosis in a cell that is about to divide quizlet?
The purpose of mitosis is to divide and replicate cells.
What is the function of mitosis in a cell that is about to divide thoroughly answer this question for full credit?
Mitosis is cell division that results in two daughter cells with the same chromosome number as the parent cell. It is a way of manufacturing more cells for growth, or to replace old, worn out cells, for repair.
What is the function of mitosis in a cell that is about to divide chegg?
