PAPER - I (Marks 100)


The candidates will be required to attempt five questions-three from Part - A and two from Part - B.



General organization (general morphology, mode of life adaptations life cycles and economic importance) of the following groups with special reference to the topics mentioned in each group

  • Protozoa: Parasitism, conjugation and autogamy, medical importance.

  • Porifera: Canal system, skeletal structures and their taxonomic value, position of porifera in the Animal Kingdom.

  • Coelenterata: Polymorphism; measenteries corals and coral reefs.

  • Platyhelminthes: Parastic adaptations, medical importance

  • Nematoda: Medical importance.

  • Anneilda: Coelom, metamerism,

  • Mollusca: Shell, modifications of foot, feeding, respiration, shell fishery,

  • Arthropoda: Appendages, feeding: respiration, larvae.

  • Echinodermata: Skeleton, water vascular system, larvae.



Origin; comparative account of skeleton, circulatory, excretory and nervous systems, development (egg types, cleavage, blastula and gastrula, germ layer/formation, embryonic membranes and placentation) natural history (mode of life, migration, adaptations, biting mechanism of snakes)
