What is Cell Division?

Cell division is the process by which a single cell divides into two daughter cells with identical genetic material. It is an essential part of normal cellular growth and development, and it occurs in both prokaryotic (bacterial) and eukaryotic (animal and plant) cells. Cell division is divided into two main categories: mitosis, which results in the production of two identical daughter cells from one parent cell, and meiosis, which produces four haploid gametes (sex cells).Mitosis consists of five stages: Prophase, Metaphase, Anaphase, Telophase and Cytokinesis. During Prophase chromosomes condense further as they begin to become visible under a microscope. In Metaphase the chromosomes line up at the center of the cell known as the metaphase plate. Next during Anaphase spindle fibers attach to each chromosome pair pulling them apart towards opposite sides of the cell. Finally Telophase marks the end of Mitosis where a new nuclear membrane forms around each group of separated chromosomes while cytokinesis separates them into two separate daughter cells containing identical genetic material. Meiosis also consists of five stages; Interphase I, Prophase I , Metaphase I , Anaphase I & Telophase I followed by Interphase II , Prophase II , Metaphse II , Anaphse II & Telophse II . The purpose of Meiosis is create sex cells or gametes for reproduction through crossing over between homologous pairs that result in random combinations as well as reductional division so that when fertilized only half will be passed on instead full set inherited from parents like with Mitosis . This all takes place during inter phase 1 where DNA replicates before entering Prophases I where chromosomes duplicate forming four copies that then cross over exchanging segments between them creating unique combinations this continues until reaching telophone 2 where finally nuclear membranes form around four unique haploid sets completing creation sex Cells or Gametes ready for reproduction.
