1.      Pseudocoelom is present in Aschelminthes phylum.

2.      Symmetry in echinodermata is radial.

3.      Comb plates are found in Ctenophora phylum.

4.      Worm-like creatures with proboscis and collar are found in Hemichordata phylum.

5.      Reptiles have three chambered heart, except crocodile which has four chambered heart.

6.      Water canal system is found in Porifera phylum while water vascular system is found in Echinodermata phylum.

7.      Operculum is found in Osteichthyes class.

8.      Parapodia may be found in Annelida phylum.

9.      Radula is found in Mollusca phylum.

10.  Coanocytes are found in Porifera phylum.

11.  Hairs are found in Mammalia class.

12.  Placoid scales are found in Chondrichthyes class.

 

5.      “All vertebrates are chordates but all chordates are not vertebrates.” Justify.

Urochordata, Cephalochordata and Vertebrata all possess a notochord at least in some stage of their life cycle. Thus, they are all Chordates. In Vertebrata the notochord is changed into a bony vertrebral column. They are, thus, called Vertebrata. But Urochordates and Chephalochordates do not have bony vertebral column. Thus, they are not Vertebrates. Therefore, all vertebrates are chordates but all chordates are not vertebrates.
