THE CELL CYCLE CELL DIVISION CELL DIVISION

Cell Division to cell division occurs growth multicellular organisms with the growth of tissues and vegetative reproduction in unicellular organisms. Note that a stem cell two daughter cells arise, not three.
types of cell division
Binary fission is the form of cell division in prokaryotes cells.
' Mitosis most common form of cell division in eukaryotic cells . A cell that has acquired certain parameters or terms of size, volume, energy storage, environmental factors can fully replicate their DNA and divide funding into two daughter cells, usually the same. Both cells are diploid or haploid , depending on the mother cell.
Meiosis is the division of a diploid cell into four haploid cells. This cell division occurs in multicellular organisms to produce haploid gametes, which can be merged later to form a diploid cell called a zygote in fertilization.
multicellular beings replace their cell envelope by cell division and is usually associated with differentiation cell. In some animals, cell division stops at some point and just aging cells. Senescent cells deteriorate and die due to aging the body. The cells stop dividing because the telomeres become increasingly shorter at each division and can not protect chromosomes . cancer cells are immortal. A enzyme called telomerase allows these cells to divide indefinitely.
The main feature of cell division in eukaryotes is the conservation of the genetic cycle control cellular and cell division, since it has remained virtually unchanged from simple organisms such as yeasts such complex creatures like humans, over biological evolution.
causes of cell division
A theory explains that there is a time when the cell begins to grow much, decreasing the area / volume. When the area of \u200b\u200bthe plasma membrane is much smaller in relation to the total volume of the cell, there are difficulties in absorption and transport of nutrients, making it necessary for cell division occurs.
