WebThe growth and division of different cell populations are regulated in different ways, but the basic mechanisms are similar throughout multicellular organisms. Most tissues of the body grow by increasing their cell number, but this growth is highly regulated to … Cell division is the process by which a parent cell divides into two daughter cells. Cell division usually occurs as part of a larger cell cycle in which the cell grows and replicates its chromosome(s) before dividing. In eukaryotes, there are two distinct types of cell division: a vegetative division (mitosis), producing daughter cells genetically identical to the parent cell, and a cell division that produces ha… WebCells regulate their division by communicating with each other using chemical signals from special proteins called cyclins.
