In biology, meiosis is the process by which one diploid eukaryotic cell divides to generate four haploid cells often called gametes meiosis is essential for sexual reproduction and therefore. Regarding mitosis and cytokinesis, one difference between higher plants and animals is that in plants a the spindles contain microfibrils in addition to microtubules, whereas animal spindles do not contain microfibrils. Originally, the term mitosis refers only to nuclear division unaccompanied by cytokinesis (which is the division of the cytoplasm), as in the case of some cells like certain fungi and in fertilized egg of many insects.
