Introduction Every somatic cell undergoes a phase called mitosis. Mitosis is the division of the nucleus to form two genetically identical nuclei. There are four phases of mitosis: prophase, metaphase, anaphase and telophase. Prior to mitosis is interphase (when the cell grows and duplicates all organelles), and post-mitosis is cytokinesis (when the cell membrane pinches…

Mitosis is the part of the cell cycle when replicated chromosomes are separated into two new nuclei. In general, mitosis (division of the nucleus) is preceded by the S stage of interphase (during which the DNA is replicated) and is often accompanied or followed by cytokinesis, which divides the cytoplasm, organelles and ...This formation of tissues begins with the root apical meristem (RAM). Just below the tip of the root, there is a region of small, densely packed cells that are actively dividing. These cells make up the RAM. To the outside (below, in your slide) of the root tip, the RAM cells produce an ephemeral tissue called the root cap.Introduction: In this lab, you will examine the dividing root-tip cells of an onion.
