XI BIOLOGY, , MAURYA SCIENCE ACADEMY, CHAPTER NO.4, , KINGDOM ANIMALIA, , , CRITERIA FOR ANIMAL CLASSIFICATION:, , 1. Number of Germ layers: In multicellular organisms, after, fertilization zygote forms. Zygote undergoes repeated cell division, [mitosis] and forms mass of cells. The mass of cells forms germinal, layers i.e. ectoderm, mesoderm and endoderm. These germinal layers, form tissues. From tissues organs are developed .From organs, system, developed. All system forms a complete body of an organism., a. Diploblastic animals: The animals made up of two germinal layers, i.e. ectoderm and endoderm is called as diploblastic animals., Ectoderm and endoderm are separated by mesogloea. Mesogloea is, non living jelly like substance which separates ectoderm and, endoderm., o Example: Phylum Cnideria /Coelenterata., , b. Triploblastic animals: The animals made up of three germinal layers, i.e. ectoderm, mesoderm and endoderm called as triploblastic animals., o Example: Phylum Platyhelminthes, Aschelminthes, Annelida,, Arthropoda, Mollusca, Echinodermata, Hemichordata and all, chordates., , 2. Animal body plan:, , 1 KINGDOM ANIMALIA, , I SIGN OUT BY DR. VIRESH SHELKE

XI BIOLOGY, , MAURYA SCIENCE ACADEMY, , a. Cell aggregate plan: In this plan, cells do not form tissues or organs, and no nervous co ordination present., o Example: Phylum Porifera, b. Blind sac body plan: In this plan, digestive cavity with a single, opening present which acts as mouth as well as anus., o Example: Phylum Cnideria, c. Tube with in tube body plan: In this plan, digestive cavity/system is, complete i.e mouth and anus present at opposite side., o Example: Phylum Annelida to hemichordata and all chordates, 3. Body symmetry: Similarity in shape, size and number of parts on, the opposite sides of median line is called as body symmetry., , a. Asymmetrical animals: The animals in which body can not be, divided into two equal parts/halves by any plane., o Example: Sponges[Porifera] and Snails[mollusca], b. Radially symmetrical animals: The animals in which body can be, cut into two similar parts/halves in a number of planes., o Example: Hydra[Cnideria],Starfish[Echinodermata], c. Bilaterally symmetrical animals: The animals in which body can, be divided into two similar parts/halves in a median /vertical plane, only, o Example: Fish [Pisces] ,Frog [Amphibians], 4. Body cavity/Coelom: The space between body wall and alimentary, canal is called as coelom. Coelom formed by splitting of mesoderm., , a. Acoelomates: The animals in which coelom is absent called as, Acoelomates. The space filled by parenchymatous tissue., 2 KINGDOM ANIMALIA, , I SIGN OUT BY DR. VIRESH SHELKE

MAURYA SCIENCE ACADEMY, , XI BIOLOGY, , o Example: Platyhelminthes, b. Pesudocoelomates: The animals in which false body cavity present, called as pesudocoelomates. The coelom lined by patches of, mesodermal cells, o Example: Phylum Aschelminthes, c. Coelomates: The animals in which true body cavity present called as, coelomates. In coelomates, mesoderm splits into outer and inner, layer. The outer layer forms inner lining of body wall and inner layer, forms outer covering of alimentary canal. In non-chordates, coelom, filled with coelomic fluid. [Cockroach: Haemocoel (blood in coelom)], o Example: Phylum Annelida to hemichordata and all chordates, 5. Body segmentation/Metamerism: The series of successive units, arranged along a length of body is known as body segmentation., o Example: Phylum Annelida and Arthropoda, , 6. Body support: The external and internal framework which supports, body called as skeleton. Skeleton is of two types:, a. Exoskeleton: External frame work of body: wings nails, claws, b. Endoskeleton: Internal framework of body: Bones, cartilage, , , , Non-Chordates:, , Absence of notochord & without, vertebral column so also known as invertebrates., , 3 KINGDOM ANIMALIA, , I SIGN OUT BY DR.
