#1. Which of the following animals are true coelomates with bilateral symmetry?
Aschelminthes are pseudocoelomates and platyhelminthes are acoelomates.
Adult echinoderms are bilaterally symmetrical.
#2. Which of the following animals does not undergo metamorphosis?
Metamorphosis refers to transformation of larva into adult. Animal that perform metamorphosis are said to have indirect development. In earthworm development is direct which means no larval stage and hence no metamorphosis.
#3. In case of poriferans the spongocoel is lined with flagellated cells called
Choanocytes (collar cells) form lining of spongocoel in poriferans (sponges). Flagella in collar cells provide circulation to water in water canal system.
#4. An important characteristic that Hemichordates share with Chordates is
Pharyngeal gill slits are present in hemichordates as well as in chordates. Notochord is present in chordates only. Ventral tubular nerve cord is characteristic feature of non-chordates.
#5. Which of the following features is not present in the Phylum-Arthropoda?
Parapodia are present in aquatic annelids like Nereis and helps in swimming.
#6. Metagenesis refers to:
In coelenterates, metagenesis is alternation of generation between polyp and medusa. Polyp reproduces asexually by budding to form medusa and medusa reproduces sexually to form polyp.
#7. Body having meshwork of cells, internal cavities lined with food filtering flagellated cells and indirect development are the characteristics of phylum:
In poriferans, the body is loose aggregate of cells (meshwork of cells). Internal cavities and canals are lined with food filtering flagellated cells i.e. choanocyte/collar cell. Choanocytes help in filter feeding.
#8. Which of the following characteristics is mainly responsible for diversification of insects on land?
#9. Which of the following endoparasites of humans does show viviparity?
#10. Select the Taxon mentioned that represents both marine and fresh water species
Echinoderms, ctenophores and cephalochordates are exclusively marine.
#11. Which one of the following living organisms completely lacks a cell wall?
#12. Planaria possess high capacity of
#13. Which group of animals belong to the same phylum?
Prawn, Scorpion and Locusta all belong to phylum arthropoda.
#14. One of the representatives of Phylum Arthropoda is
#15. Which of the following are correctly matched with respect to their taxonomic classification?
#16. One example of animals having a single opening to the outside that serves both as mouth as well as anus is
Organisms having single opening to outside that serves both mouth as well as anus have incomplete digestive system.
- Fasciola – incomplete digestive system (Platyhelminthes)
- Octopus – (Mollusca) complete digestive system
- Asterias – (Echinodermata) complete digestive system
- Ascidia – (Urochordata) complete digestive system
#17. Which one of the following kinds of animals are triploblastic?
Triploblastic refers to organisms having three germ layers- ectoderm, mesoderm and endoderm.
(1) Corals (Cnidarians) – Diploblastic organisms
(2) Flatworms (Platyhelminthes) – Triploblastic
(3) Sponges (Porifera) – Diploblastic
(4) Ctenophores – Diploblastic
#18. Which one of the following statements about certain given animals is correct?
Flatworms are acoelomates (not coelomates) Roundworms/Aschemlminthes are pseudocoelomates Molluscs are schizocoelomates (not acoelomates) Insects are schizocoelomates (not pseudocoelomates
#19. Which one of the following groups of animals is bilaterally symmetrical and triploblastic?
#20. If a live earthworm is pricked with a needle on its outer surface without damaging its gut, the fluid that comesout is
#21. Ascaris is characterized by
Ascaris belong to phylum Aschelminthes. Aschelminthes are pseudocoelomate i.e. false coelom is present and have unsegmented body. Thus, metamerism is absent in Ascaris.
#22. Which one of the following is not a characteristic of phylum Annelida?
Annelida phylum belong to non-chordate hence have ventral nerve cord. Annelid possesses closed circulatory system and true segmentation. Annelid possess true coelom hence are eucoelomate. Annelids are not pseudocoelomate
#23. What is true about Nereis, Scorpion, Cockroach and Silver fish?
#24. Which one of the following pairs is mismatched?
Pinctada (Pearl oyster) is famous for pearl formation.
#25. Metameric segmentation is the characteristic of
Metameric segmentation (true segmentation) is characteristic feature of Annelid and arthropoda. Body of arthropods is segmented.
#26. Biradial symmetry and lack of cnidoblasts are the characteristics of
Presence of cnidoblast is characteristic feature of cnidaria. Ctenoplana and Beroe belong to phylum Ctenophora. Ctenophores are radially symmetrical and cnidoblast cells are absent.
#27. Two common characters found in centipede, cockroach and crab are
Centipede, Cockroach and Crab belong to Arthropoda. Arthropodes bear jointed legs and have chitinous exoskeleton.
#28. From the following statements select the wrong one
Animals belonging to phylum porifera are mostly marines but some members live in fresh water also e.g. Spongilla (fresh water sponge).
#29. In contrast to annelids the platyhelminths show
#30. Which one of the following groups of animals reproduce only by sexual means?
Ctenophores reproduce exclusively by sexual means only but sponges, cnidarians and protozoans undergo asexual means of reproduction also (fragmentation, budding, fission respectively)
