(c) Euspongia - Scypha
(d) Spongilla - bath sponge
Show Answer & Explanation

Answer: (b) Euplectella - Venus flower basket

Explanation:
1. Euplectella is the Venus flower basket. Sycon (Scypha) is a marine sponge, Spongilla is the fresh water sponge and Euspongia is the bath sponge.

Question 2: Which of the following is incorrect for phylum Porifera?
(a) Development is indirect, with a larval stage
(b) They are hermaphrodite
(c) The body is supported by a skeleton of spicules and spongin fibres
(d) Fertilisation is both internal and external
Show Answer & Explanation

Answer: (d) Fertilisation is both internal and external

Explanation:
1. Sponges are hermaphrodites with internal fertilisation and indirect development. Fertilisation is not external.

Question 3: Which function is not performed by cnidoblasts of coelenterates?
(a) Anchorage
(b) Defence
(c) Capture of prey
(d) Reproduction
Show Answer & Explanation

Answer: (d) Reproduction

Explanation:
1. Cnidoblasts (stinging cells) help in anchorage, defence and capture of prey. Reproduction is carried out by gametes and buds.

Question 4: When polyps produce medusae asexually and medusae form polyps sexually, the phenomenon is called
(a) Metagenesis
(b) Metachrosis
(c) Polymorphism
(d) Retrogressive metamorphosis
Show Answer & Explanation

Answer: (a) Metagenesis

Explanation:
1. Alternation of a sexual generation with an asexual one, as in Obelia, is metagenesis.

Question 5: Which statement about flatworms is not correct?
(a) Most flatworms are endoparasites of animals, including humans
(b) A flatworm like Taenia has an incomplete alimentary canal and flame cells as respiratory organs
(c) They are dorsoventrally flattened and acoelomate
(d) They are mostly monoecious and their development passes through several larval forms
Show Answer & Explanation

Answer: (b) A flatworm like Taenia has an incomplete alimentary canal and flame cells as respiratory organs

Explanation:
1. Tapeworm has no alimentary canal at all, and flame cells are excretory (osmoregulatory), not respiratory.

Question 6: Which is the correct pair of respiratory structure and animals in which it is found?
(a) Tracheal system - Culex and Nereis
(b) Book gills - Locusta and Limulus
(c) Gills - prawn and Unio
(d) Book lungs - crab and spider
Show Answer & Explanation

Answer: (c) Gills - prawn and Unio

Explanation:
1. Prawn and Unio breathe with gills. Nereis uses parapodia, Locusta has tracheae (Limulus has book gills) and crabs have gills (spiders have book lungs).

Question 7: The special mode of feeding by radula is found in
(a) Sea mouse
(b) Sea fan
(c) Sea lily
(d) Sea hare
Show Answer & Explanation

Answer: (d) Sea hare

Explanation:
1. Radula is a rasping organ of molluscs. Sea hare (Aplysia) is a mollusc, while sea mouse is an annelid and sea fan and sea lily are cnidarian and echinoderm.

Question 8: Match the phylum with its level of organisation: 1 Porifera, 2 Platyhelminthes, 3 Echinodermata, 4 Coelenterata with a tissue level, b organ-system level, c cellular level, d organ level.
(a) 1-a, 2-c, 3-d, 4-b
(b) 1-b, 2-c, 3-a, 4-d
(c) 1-c, 2-d, 3-b, 4-a
(d) 1-c, 2-b, 3-d, 4-a
Show Answer & Explanation

Answer: (c) 1-c, 2-d, 3-b, 4-a

Explanation:
1. Porifera show cellular grade, Platyhelminthes organ level, Echinodermata organ-system level and Coelenterata tissue level.

Question 9: Which of the following animals are true coelomates with bilateral symmetry?
(a) Adult echinoderms
(b) Aschelminthes
(c) Platyhelminthes
(d) Annelids
Show Answer & Explanation

Answer: (d) Annelids

Explanation:
1. Annelids have a true coelom and bilateral symmetry. Adult echinoderms are radial, aschelminths have a pseudocoelom and flatworms are acoelomate.

Question 10: Bioluminescence is well marked in
(a) All members of coelenterata
(b) Platyhelminthes and annelida
(c) Members of ctenophora
(d) Mollusca and hemichordata
Show Answer & Explanation

Answer: (c) Members of ctenophora

Explanation:
1. Ctenophores (comb jellies) are well known for bioluminescence.

Question 11: Which group has bilateral symmetry?
(a) Tapeworm, silkworm, starfish
(b) Balanoglossus, Pleurobrachia, Ascaris
(c) Ascaris, Leucosolenia, butterfly
(d) Scorpion, butterfly, Ascaris
Show Answer & Explanation

Answer: (d) Scorpion, butterfly, Ascaris

Explanation:
1. Scorpion, butterfly and Ascaris are all bilaterally symmetrical. Adult starfish are radial, Pleurobrachia is biradial and Leucosolenia is asymmetrical or radial.

Question 12: True coelom appeared for the first time in the course of evolution in
(a) Annelida
(b) Mollusca
(c) Chordata
(d) Protozoa
Show Answer & Explanation

Answer: (a) Annelida

Explanation:
1. Annelids are the first animals with a true, mesoderm-lined coelom (they are also the first metameric animals).

Question 13: A characteristic feature of Echinodermata is
(a) Smooth skin and radial symmetry
(b) Spiny skin and radial symmetry
(c) Spiny skin and asymmetry
(d) Smooth skin and bilateral symmetry
Show Answer & Explanation

Answer: (b) Spiny skin and radial symmetry

Explanation:
1. Echinoderm means spiny skin. The adults are radially symmetrical and the larvae are bilateral.

Question 14: Locomotory structures in annelida are
(a) Parapodia
(b) Setae
(c) Longitudinal and circular muscles
(d) All of these
Show Answer & Explanation

Answer: (d) All of these

Explanation:
1. Aquatic annelids like Nereis use parapodia, earthworms use setae with the longitudinal and circular body wall muscles.

Question 15: What is common to the phyla Platyhelminthes, Aschelminthes and Annelida?
(a) Bilateral symmetry
(b) Coelom
(c) Segmentation
(d) All of the above
Show Answer & Explanation

Answer: (a) Bilateral symmetry

Explanation:
1. All three are bilaterally symmetrical and triploblastic. Only annelids have a true coelom and segmentation.

Question 16: The specialised cells that help in osmoregulation and excretion in Platyhelminthes are
(a) Choanocytes
(b) Cnidocytes
(c) Flame cells
(d) Renette cells
Show Answer & Explanation

Answer: (c) Flame cells
