Echinodermata

Given below are the pair of phyla with their body cavities. {:(,"Phylum","Body cavity"),(I., "Platyhelminthes",-"Pseudocoel"),(II.,"Annelida",-"Schizocoel"),(III,"Nematoda",-"No body cavity"),(IV.,"Echinodermata ",-"Enterocoel"):} Choose the option with the correct codes

The body of an individual can be divided into equal halves by any plane pasing through the center from top to bottom. This type of symmetry is found in I. Cnidaria II. Echinodermata III. Coelenterata IV. Mammals

Match column I with column II and select the correct option from the codes gives below. {:(Column I,Column II),(A."Hirudin",(i)"Hydra"),(B."Canal system",(ii)"Echinodermata"),(C."Nematocysts",(iii)"Leech"),(D."Feather star",(iv)"Sponges"),(E."Insects",(v)"Termites"):}

The name of phylum is derived from certain features of animals. Select that how many of these are correct. A. Cnidaria-Cnidoblasts/cnidocytes b. Latworms -Dorso-ventrally flattened body c. Platyhelminthes-Circular cross section d. Aschelminthes-Body surface is indistinctly Marked out into segments or metameres e. Echinodermata-Exoskeleton of calcareous ossicles.
