Detailed explanation-1: -Cells regulate their division by communicating with each other using chemical signals from special proteins called cyclins. These signals act like switches to tell cells when to start dividing and later when to stop dividing.
Detailed explanation-2: -Most of the time when people refer to “cell division, ” they mean mitosis, the process of making new body cells. Meiosis is the type of cell division that creates egg and sperm cells. Mitosis is a fundamental process for life.
Detailed explanation-3: -The form of cell division known as mitosis is responsible for the body’s expansion and repair. Gametes are created as a result of the cell division process known as meiosis.
Detailed explanation-4: -No, all cells do not divide at the same rate. Cells that require frequent replenishing, such as skin or intestinal cells, may only take roughly twelve hours to complete a cell cycle. Other cells, such as liver cells, remain in a resting state (interphase) for up to a year before undergoing division.
