#1. Which of the following animals are true coelomates with bilateral symmetry?

Annelids

Adult Echinoderms

Aschelminthes

Platyhelminthes

Annelids exhibit bilateral symmetry with metameric segmentation where external segments correspond to internal segments.

Aschelminthes are pseudocoelomates and platyhelminthes are acoelomates.

Adult echinoderms are bilaterally symmetrical.

#2. Which of the following animals does not undergo metamorphosis?

Earthworm

Tunicate

Starfish

Moth

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

Ostia

Oscula

Choanocytes

Mesenchymal cells

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

Absence of notochord

Ventral tubular nerve cord

Pharynx with gill slits

Pharynx without gill slits

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?

Jointed appendages

Chitinous exoskeleton

Metameric segmentation

Parapodia

Parapodia are present in aquatic annelids like Nereis and helps in swimming.

#6. Metagenesis refers to:

Presence of a segmented body and parthenogenetic mode of reproduction

Presence of different morphic forms

Alternation of generation between asexual and sexual phases of an organism

Occurrence of a drastic change in form during post-embryonic development

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:

Protozoa

Coelenterata

Porifera

Mollusca

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?

Eyes

Segmentation

Bilateral symmetry

Exoskeleton

#9. Which of the following endoparasites of humans does show viviparity?

Ascaris lumbricoides

Ancylostoma duodenale

Enterobius vermicularis

Trichinella spiralis

#10. Select the Taxon mentioned that represents both marine and fresh water species

Echinoderms

Ctenophora

Cephalochordata

Cnidaria

Echinoderms, ctenophores and cephalochordates are exclusively marine.

#11. Which one of the following living organisms completely lacks a cell wall?

Cyanobacteria

Sea-fan(Gorgonia)

Saccharomyces

Blue-green algae

#12. Planaria possess high capacity of

Metamorphosis

Regeneration

Alternation of generation

Bioluminescence

#13. Which group of animals belong to the same phylum?

Earthworm, Pinworm, Tapeworm

Prawn, Scorpion, Locusta

Sponge, Sea anemone, Starfish

Malarial parasite, Amoeba, Mosquito

Prawn, Scorpion and Locusta all belong to phylum arthropoda.

#14. One of the representatives of Phylum Arthropoda is

Silverfish

Pufferfish

Flying fish

Cuttlefish

#15. Which of the following are correctly matched with respect to their taxonomic classification?

Flying fish, cuttlefish, silverfish, - Pisces

Centipede, millipede, spider, scorpion - Insecta

House fly, butterfly, tsetsefly, silverfish - Insecta

Spiny anteater, sea urchin, sea cucumber -Echinodermata

#16. One example of animals having a single opening to the outside that serves both as mouth as well as anus is

Fasciola

Octopus

Asterias

Ascidia

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?

Corals

Flat worms

Sponges

Ctenophores

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?

Flat worms (Platyhelminthes) are coelomates

Round worms (Aschelminthes) are pseudocoelomates

Molluscs are acoelomates

Insects are pseudocoelomates

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?

Aschelminthes (Roundworms)

Ctenophores

Sponges

Coelenterates (Cnidarians)

#20. If a live earthworm is pricked with a needle on its outer surface without damaging its gut, the fluid that comesout is

Coelomic fluid

Haemolymph

Slimy mucus

Excretory fluid

#21. Ascaris is characterized by

Presence of true coelom and metamerism (metamerisation)

Absence of true coelom but presence of metamerism

Presence of neither true coelom nor metamerism

Presence of true coelom but absence of metamerism

Ascaris belong to phylum Aschelminthes. Aschelminthes are pseudocoelomate i.e. false coelom is present and have unsegmented body. Thus, metamerism is absent in Ascaris.
