Question

Match the following columns (I) and (II):

Column I	Column II
(a) Porifera	(i) Roundworms
(b) Echinodermata	(ii) Tube feet
(c) Bony fish	(iii) Osculum
(d) Mammals	(iv) Frog
(e) Nematoda	(v) Chameleon
(f) Protochordata	(vi) Balanoglossus
(g) Amphibia	(vii) Labeo
(h) Reptilia	(viii) Jointed appendages
(i) Annelida	(ix) Pinna
(j) Arthropoda	(x) Segmented worms

Accepted Answer

(a)-(iii), Porifera have a cavity in the centre called spongocoel with a single large opening osculum at the upper end.

(b)- (ii), The body cavity of Echinodermata is modified into a unique water vascular system that moves organs of respiration and locomotion, the tube feet or podia.

(c)- (vii), They are exclusively aquatic animals and are called fishes. They obtain dissolved oxygen from water by making use of their respiratory organs known as gills.

(d)-(ix), The mammals are warm-blooded animals with four-chambered heart. A fleshy external ear called pinna is present.

(e)- (i), They are bilaterally symmetrical and triploblastic like Platyhelminthes. But the body is cylindrical (or round like) rather than flattened unlike that of flatworms and hence also called roundworms.

(f)- (vi), They are bilaterally symmetrical, triploblastic and coelomic animals. They possess the notochord at some stage of their life. Examples are Herdmania, Amphioxus and Balanoglossus.

(g)- (iv), They differ from the fishes in lacking scales on the skin, having mucus glands in the skin, and having a three-chambered heart. Respiration occurs either through gills or the lungs.

(h)- (v), They are cold-blooded terrestrial or aquatic vertebrates. Their body is covered by scales which prevent the loss of water. The body is divided into head, neck, trunk and tail.

(i)- (x), They are also bilaterally symmetrical and triploblastic but they have a true body cavity (called coelom). This allows true organs to be packaged in the body structure. Hence, there is extensive organ differentiation. The differentiation occurs in a segmental fashion. The segments are lined up one after another from head to tail due to which they are also called segmented worms.

(j)- (viii), Phylum Arthropoda includes the animals comprising exoskeleton made of chitin and jointed appendages.

(f) Spiny skinned animals	(vi) Annelida
