Tube Within Tube Body Plan
An organism having two separate openings, one acting as a mouth and the other acting as an anus is said to have Tube within the tube body plan. It is called so because the alimentary canal which is a tube, is present within the body wall which is also a tube. This type of body plan is found in seven kingdoms, namely, Aschelminthes, Annelida, Arthropoda, Mollusca, Echinodermata, Hemichordata, and Chordata. There are two types of tubes within tube animals – Protostomes and Deuterostomes
Difference Between Protostomes and Deuterostomes
The key difference between Protostomes and Deuterostomes lies in the development of their embryonic cells, with protostomes forming the mouth first during embryogenesis, while deuterostomes develop the anus first. Protostomes and Deuterostomes are two types of organisms with tubes within a tube body plan
The major difference between these two is based on the fate of Blastopore. In this article, we will cover the difference between Protostomes and Deuterostomes.
