Q:

Why does mitosis occur?

A:

Mitosis, the process of cell division, occurs to ensure growth and repair in multicellular organisms. Mitosis starts with one parent cell and results in two identical daughter cells. Mitosis perpetually generates new cells until the organism dies, according to Dr. Stephen M. Wolniak.

Full Answer

Mitosis is essential in the survival of multicellular organisms. In these organisms, mitosis occurs immediately after genesis. Cells continue to duplicate until the organism is fully developed. An adult human, for example, is made up of trillions of cells. Some of these cells become specialized and perform unique functions in the body. Cells that make up tissue, bones and organs all work together to help organisms function properly. With the exception of specialty cells, like brain cells, cells that die are constantly replaced by new ones.

Mitosis takes the genetic information of a parent cell and replicates it in the form of two identical daughter cells. This process occurs in four stages. During Prophase, chromosomes condense in the form of a tight coil as the nuclear membrane breaks down. During Metaphase, the replicated chromosomes move toward the middle of the cell, ensuring there is an equal amount of genetic material on each side. During Anaphase, the chromatids begin to pull apart toward the poles of the cell. During Telophase, the cell splits apart and the daughter cells are officially formed.

  • Q:

    What are three similarities between mitosis and meiosis?

    A:

    Mitosis and meiosis are multistage processes involving division of the cell. They both involve cellular DNA duplication, splitting the chromosomes into the daughter cells. They both involve degradation and reformation of the nuclear membrane.

  • Q:

    Why does cell division occur?

    A:

    Cell division, also called mitosis, occurs in multicellular organisms to create tissues, organs and organ systems. It is a method of asexual reproduction in unicellular organisms, and it occurs because it’s essential for increasing the population of the organisms.

  • Q:

    What role does mitosis play in the growth of an embryo?

    A:

    Mitosis, or normal cell division, and the deposition of extracellular materials are the ways that an embryo grows. However, in the early stages of development, the cell undergoes mitosis without growing. The egg cell is much larger than normal body cells, and so it can divide many times before growing.

  • Q:

    Where does mitosis occur?

    A:

    Mitosis takes place in the cells of eukaryotic organisms. The process starts in the cells nucleus with the DNA condensing, and the nuclear envelope or membrane breaking down to give the chromosomes room to move during the process instead of sticking to the envelope.
