Discover the body plans of the three types of Porifera. Triploblastic animals have three germ layers (ectoderm, mesoderm, and endoderm) and three basic body plans related to body cavities (acoelomate, pseudocoelomate, and coelomate). SUBJECT and GRADE Life Sciences Grade 11 TERM 1 Week 7 TOPIC Biodiversity of animals AIMS OF LESSON At the end of this lesson you should be able to know the following: The concept of a phylum The six phyla: Porifera, Cnidaria, Platyhelminthes, Annelida, Arthropoda and Chordata (Comparative table of: four key features i. This profusion of animal phyla occurred 533-525 million years ago. Flatworms (Phylum Platyhelminthes) This phylum contains some 20,000 Asymmetrical body plans are relatively rare in the animal kingdom. The first of the worm phyla is Platyhelminthes, commonly called flatworms. Which phylum does an animal belong to, if it has stinging tentacles and a mouth, but no anus? A. 28. snail c. Finally, explore how they support their bodies with spicules in the absence of a skeletal system. Blind Sac Plan: The body has a single cavity with one opening to the outside. In some species, the corona can also be used to propel the rotifer CLASSIFICATION: Only answer the phyla, classes, subclasses and other classification that you are responsible for knowing this week for Lab 6 A)Phylum Annelida B)Phylum Mollusca C)Phylum Nematoda D)Platyhelminthes E)Class The Animal kingdom contains about 30 phyla, however in Grade 11 we are only going to look at six: Porifera, Cnidaria, Platyhelminthes, Annelida, Arthropoda and Chordata. All animals belong to the Kingdom Animalia. Mollusca. Sponges (Phylum Porifera): They are the earliest and the simplest form of filter feeders that have a porous body structure. Muscle Contraction: Actin and Myosin: Proteins crucial for muscle contraction. Term. Sponge b. Compare and contrast the polyp and medusa forms of cnidarians in terms of body structure, mobility, and lifestyle. The A phylum is a taxonomic rank below kingdom and above class. What is the difference between a hard, prickly sponge and a soft sponge? Hard, prickly sponges contain spicules while soft sponges Answer to BIOL 202 Spring 2019 Homework 1.

Flashcards; Learn; Depending on the classification scheme, there are roughly 34 animal phyla. D. Compare the body plan of a sponge to a cnidarian, explain how these change. excretory cells that remove metabolic waste and excess water from the body of flatworms. basic body plan in cnidarians such as jellyfish that is tubular in shape and typically sessile; Cnidaria: (10,000 species) Although the freshwater hydra is a much-studied representative, it is not typical of the class as most members are: marine; colonial; produce two body forms – the sessile polyp (like the hydra) and the free This form of symmetry marks the body plans of many animals in the phyla Cnidaria, including jellyfish and adult sea anemones (Figure 27. An example of the polyp form is Hydra spp. Animal diversity reflects shared ancestry among different phyla. shown here in a cross section of a generalized worm body. Study with Quizlet and memorize flashcards containing terms like What are the distinguishing animal characteristics?, List the characteristics that divide the animal Phyla?, List the characteristics that unite all animals. Cnidarians live primarily in marine environments. 7 invertebrate Phyla-Porifera-Cnidaria-Platyhelminthes-Mollusca-Annelida-Nemotoda-Arthropods. They have a basic body plan that includes a radially symmetrical structure with two main body forms: the polyp PHYLUM - ECHINODERMATA . Arthropods, Which would be a great surprise if found in the body of a sponge? A. 1 / 236. Use different colours if you have more than one Animals in this phylum display two distinct morphological body plans: polyp or “stalk” and medusa or “bell” (Figure 2). Phylum (plural: phyla) is a taxon used in the scientific classification of life. Describe the echinoderm body plan and compare the major echinoderm lineages. 404 Evolutionary Tree of Animals Similarities between Porifera and Cnidaria: They both are multicellular eukaryotes. This is such a simplistic structure because the body plan has only one large internal chamber, called a Organisms in the phylum Cnidaria possess either radial or biradial symmetry. has muscles and nerve cells Submit, Which Below is a list of some general characteristics of the phylum Platyhelminthes. Explain the basic body plan of members of the Kingdom Animalia. While Phylum Cnidaria includes animals that show radial or biradial symmetry and are diploblastic, that is, they develop from two embryonic layers. Polyp forms are sessile as adults, with a single opening to the digestive system (the mouth) facing up with tentacles surrounding it. Subject areas. Flatworms (Phylum Platyhelminthes): Organisms which are soft-bodied and have bilateral symmetry such as those belonging to the Porifera, Cnidaria, Platyhelminthes, Mollusca, Annelida, Nematoda, Arthropoda, Echinodermata, Chordata. Porifera, Cnidaria and Phylum Platyhelminthes belongs to kingdom Animalia. Their body surface is distinctly marked out into segments or metameres [metamerically segmented] and, Study with Quizlet and memorize flashcards containing terms like Illustrate the evolutionary relationship between Porifera, Cnidaria, and Platyhelminthes. The animal kingdom is divided into major phyla including porifera, cnidaria, platyhelminthes, nematoda, annelida, arthropoda, mollusca, echinodermata, and chordata. Members of the Phylum Annelida are the segmented worms and are abundant in all habitats. Label the groups Study with Quizlet and memorize flashcards containing terms like This animal phylum is comprised of segmented worms Annelida Nematoda Porifera Platyhelminthes Cnidaria, Protostomes differ from deuterostomes in which of the following embryological features Origin of coelom Cleavage pattern of the embryonic cells Developmental fate of cells Both A & B All of Experiment 2: Creating a Phylum Key Data Tables Table 2: Phylum Taxonomic Key Porifera Cnidaria Platyhelminthes Annelida Arthropoda Mollusca Echinodermata Speciali zed cell, but no tissues Hollow body cavity for food Three tissue layers, no body cavity Setae used for moveme nt Bilateral phylum with segmentati on Most have calcium- containin g Phyla Comparison: Phyla are groups of animals that share a common ancestor and can be divided with the help of any one of several different techniques. c. What are the common organisms of each Phylum? What is the symmetry, digestive tract, and other distinguishing characteristics? Answer these questions for Phylum Porifera, Cnidaria, Platyhelminthes, Nematoda, Annelida, Mollusca, Arthropoda, Echninodermata, and Chordata. Most animals have either bilateral or radial symmetry. C. Whittaker’s five classification system, Processed in 1969, characterizes living organisms into Five-Kingdom Classification: Kingdom Monera, Kingdom Protista, The Phylum Cnidaria is notable for its remarkable diversity, encompassing classes such as Hydrozoa, Scyphozoa, and Anthozoa, each exhibiting unique adaptations that allow them to thrive in a variety of marine environments.

The medusa ("jellyfish") is a floating form, and looks like an upside-down version of the polyp. Body divided into segments that are Tough exoskeleton => chitin 3. Flashcards Place each of the following organisms into its proper phylum (Porifera, Cnidaria, Annelida, Mollusca, Platyhelminthes): bacteria, and organic material that is in the water which they pump through their body. Arthropods have an exoskeleton made principally of chitin—a waterproof, tough polysaccharide composed of N-acetylglucosamine. Organisms are classified for several advantages including making the study of living things easier, helping with identification, and indicating evolutionary relationships. 7b, c). Members of the phylum Cnidaria include hydras, jellyfish, sea corals, and sea anemones. , Compare the three phyla according to symmetry, presence of tissues, if tissues present whether diploblastic or triploblastic.
