In examining an unknown animal species during its embryonic development, from the first development of mouth or anus, one can determine its protostome or deuterostome.

The oral end of the majority of coelomate invertebrates emerges from the blastopore, the first developmental opening, and is referred to as a protostome (Latin for "first mouth").

The oral end of the animal originates from the second aperture on the dorsal surface of the animal in the deuterostomes ("second mouth"), which include Echinodermata and the ancestors of the Chordata; the blastopore becomes the anus. The deuterostomes also exhibit indeterminate development, meaning that even if the eight cells of the embryo are split, each one would still be able to develop into a complete organism.

Mitotic division in onion root cells:

  1. Prophase: the emergence of chromatin threads that form chromosomes, the chromosomes are visible and overlap.
  2. Metaphase: chromosomes line up and line up in the middle of the equatorial plane. The centromere of the chromosome appears to have bonds with the kinetochores connected to the spindle threads.
  3. Anaphase: the centromere of the chromosome undergoes division then the chromosomes are pulled by the spindle threads towards the two opposite poles and leave the center of the equator that looks empty.
  4. Telophase: The cytoplasm divides into two identical-looking daughter cells. At the telophase stage, the process of cell division occurs in two parts and has identical properties.

Mitosis is a cell division through the stages of prophase, metaphase, anaphase, and telophase. The purpose of mitosis is for growth and regeneration which results in two daughter cells that are identical to the original parent cell. Mitosis occurs only once and lasts only during somatization.
