Members of this phylum range in size from a single-celled organism to around 2-3 feet long. Most Platyhelminthes are parasites on other animals, only the Turbellarians are mostly non-parasitic. What are the Morphological, Anatomical, Physiological and Reproductive Adaptations of Parasites such as Platyhelminthes, Nematodes, Protozoa, Insects and Parasitic Plants Immunological Adaptations. Most of the flatworms are classified in the superphylum Lophotrochozoa, which also includes the mollusks and annelids. 1. Phylum Platyhelminthes is composed of the flatworms: acoelomate organisms that include many free-living and parasitic forms. Flatworms were once divided into three groups. Parasitic flatworms possess organs of attachment such as suckers or hooks or both. Find PowerPoint Presentations and Slides using the power of XPowerPoint.com, find free presentations research about Parasitic Adaptations In Platyhelminthes PPT All three of the parasitic groups have what are called holdfasts, which resemble jagged, toothed suckers. The parasitic flatworms have undergone tremendous amount of modifications to adapt to their parasitic mode of life. They are bilaterally symmetrical and lack specialized respiratory, skeletal, and circulatory systems; no body cavity (coelom) is … They are unsegmented and soft-bodied invertebrate animals having flattened shapes that help in diffusion of … A few species are commensalists living in harmony – or mutual benefit – with another, normally larger organism. Types of parasitism in protozoa and human diseases. Platyhelminthes (flatworms) have captivated the imagination of biologists for centuries. Parasitic Adaptations Parasitic flatworms have hooks on their mouths that allow them to securely attach to their hosts. Phylum Platyhelminthes belongs to kingdom Animalia. PARASITIC ADAPTATIONS OF TAPEWORMS AND FLUKES * have suckers & hooks so that they can attach to the host * have a tough tegument to prevent being digested by the host (tapeworm) or they have a cuticle (flukes) * absent or reduced digestive, circulatory, and muscular systems as they are parasites living inside a host Microscopy Research and Technique Volume 42, Number 3, August 1,1998 Topical Papers Histology of Parasitic Platyhelminthes Guest Editor: Jean-Lou Justine Jean-Lou Justine Introduction to Histology of Parasitic Platyhelminthes 173 Geoffrey N.
