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.Continue Reading
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.Learn more about Cells
Cellular reproduction requires a nucleus and a mitochondria in order to perform mitosis, the process of cell division. Mature red blood cells do not contain a nucleus or mitochondria, making mitosis impossible.Full Answer >
Meiosis is the process of cell division that creates offspring in sexually reproducing organisms, explains a University of Illinois at Chicago website. Unlike during mitosis, meiotic cell division starts with double the number of chromosomes in diploid parent cells. Meiosis cuts this number in half forming two haploid daughter cells. When these daughter cells combine and undergo fertilization, a zygote is created and the cell begins to develop.Full Answer >
The importance of mitosis to living organisms is that it allows organisms to grow in size and repair themselves. When an organism grows, its cells do not grow larger; they divide to make more of themselves through the process of mitosis, or cell division.Full Answer >
The purpose of mitosis is for cell growth and repair in multicellular organisms. In humans, babies begin as one cell when the egg and sperm combine, and then mitosis divides the cell into two identical cells. These cells divide further until the human has billions of cells. Cells undergo mitosis before they degrade to prevent deterioration, so mitosis helps repair human tissue.Full Answer >
