Why is it important for both eukaryotic and prokaryotic cells to go through cell division?
Naya [18.7K]

Answer:

La división celular es una parte muy importante del ciclo celular en la que una célula inicial se divide para formar células hijas.1​Debido a la división celular se produce el crecimiento de los seres vivos. En los organismos pluricelulares este crecimiento se produce gracias al desarrollo de los tejidos y en los seres unicelulares mediante la reproducción asexual.

Los seres pluricelulares reemplazan su dotación celular gracias a la división celular y suele estar asociada con la diferenciación celular. En algunos animales la división celular se detiene en algún momento y las células acaban envejeciendo. Las células senescentes se deterioran y mueren debido al envejecimiento del cuerpo. Las células dejan de dividirse porque los telómeros se vuelven cada vez más cortos en cada división y no pueden proteger a los cromosomas como tal.

Las células hijas de las divisiones celulares, en el desarrollo temprano embrionario, contribuyen de forma desigual a la generación de los tejidos adultos.
