Back to Schedule Printer Doc PDF Acoelomates and Pseudocoelomates - THIS WORMY WORLD I. The Bilateria A. Includes all phyla above Cnidaria and Ctenophora Characteristics: a. Bilateral symmetry - adapted for motility b. Triploblastic - ectoderm, mesoderm and endoderm c. Organ-system level of complexity: e.g. digestive, excretory, nervous, reproductive systems d. Cephalization - concentration of nerve ganglia in head region. Adapted for motility. II. The Acoelomates - lacking a body cavity between body wall and gut. A. Phylum Platyhelminthes - the flatworms, especially free-living. Characteristics a. Gut, if present, without anus b. Cephalization not strongly developed c. High surface-volume ratio as a result of flat shape (Important in locomotion and in exchange of materials in parasitic forms). d. No circulatory system. Organs near surface of exchange. Locomotion a. Small turbellarians ciliated, swim b. Larger turbellarians travel on substrate, use cilia and distribute weight. c. Longitudinal, circular and dorso-ventral muscles contract against tissue fluids, which serve as a "hydrostatic skeleton". This enables the animal

Unit 4: Acoelomate Animals: Phylum Platyhelminthes, Phylum Nemertea 1. Discuss the current triploblastic acoelomate body plan. 2. Discuss the concept of the organ/system level of organization and apply this to the phylums to be studied in this unit. 3. Define bilateral symmetry and cephalization. 4. Compare the enbryo development in cnidarians and in the higher metazoa, including presence, formation and function of the mesoderm. 5. Explain what excretion consists of and tell why excretory systems are necessary in the more complex animal groups. 6. Describe flame cells and their function in general, and the excretory system of planaria in particular. 7. Briefly describe these advances of the flatworms over previously studied phyla: symmetry, nervous and sensory systems, mesoderm formation, muscle systems, excretory systems, digestive systems and reproductive systems. 8. Explain the terms hermaphroditic, monoecious and dioecious, and state what animal types in general are hermaphroditic. 9. List features which will be expected in higher phyla but are not possessed by the flatworms, and tell why these features are unnecessary in flatworms.

Main Page See live article Alphabetical index Acoelomata Acoelomates consist of two modern phyla of worms the Platyhelminthes and Nemerteans. These animals are quite common with perhaps 20,000 species known. Some are free living. Many are parasitic. Although the acoelomates are triploblastic with three germ layers in the developmental forms, they are developmentally more primitive than the coelomate phyla. They are therefore thought to have evolved prior to the coelomates arthropods chordates , etc). They are the most primitive forms with bilateral symmetry and having a head and internal organs. They have no body cavity . Their digestive systems are primitive at best a pit with a single opening rather than a tube with a mouth and anus. In many cases, nutrients are absorbed through the skin rather than eaten and digested. This article is from Wikipedia . All text is available under the terms of the GNU Free Documentation License

Cours de Biologie Licence Biologie Animale Chapitre 3 : acoelomates et pseudo-coelomates Biologie Animale Chapitre 3 : Les Métazoaires Triploblastiques Acœlomates et Pseudo-cœlomates Chez les métazoaires triploblastiques, il y a apparition du mésoderme (troisième feuillet embryonnaire) qui dérive de l’endoderme pendant le développement embryonnaire. L’ectoderme et l’endoderme ont des fonctions bien définies ; le mésoderme permet la différenciation d’organes internes (appareil excréteur, organes génitaux) dont la musculature qui permettra des mouvements orientés (locomotion). Il apparaît le déplacement dans une direction donnée : les animaux ont maintenant un avant et un arrière. Apparition de la symétrie bilatérale La symétrie bilatérale remplace la symétrie radiaire des cnidaires ; l’animal a donc une région antérieure, une postérieure et une orientation dorso-ventrale. Cette symétrie existe à l’état embryonnaire mais peut disparaître chez l’adulte comme chez les oursins pentaradiés ) ou chez les gastéropodes Cette symétrie bilatérale est un des principaux facteurs qui vont infléchir le cours de l’évolution animale.
