PAPER I (Marks-100)

INVERTEBRATE AND CHORDATE ZOOLOGY

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

PART - A

Invertebrate

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.

PART - B

Chordata

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).

PAPER - II (Marks 100)

GENERAL ZOOLOGY

The candidates will be required to attempt at least one question from each part.

Part - A

Cell Biology: Morphology. Chemical composition and functions of nucleus, nuclear inclusions and cytoplasmic organelles, protein synthesis and molecular genetics. mechanism of mitosis and meiosis.

Part - B

General Physiology: Respiration, respiratory mechanism, respiratory pigments, transport of oxygen and carbon dioxide, circulation : haemodynamics, control of cardiovascular system, nutrition: modes of nutrition, digestion and assimilation of food stuff, Excretion: nature and sources of substances excreted, modes of excretions, Nervous system, nerve impulses, Hormones and their biological action.

Part - C

Genetics: Mendelian principles, multiple alleles, interaction of genes: linkage and crossing over, mapping of genes, sex determination and sex linkage, mutations, chromosoinal aberrations, gene concept.

Part - D

Evolution: Origin of life, organic diversity, theories to account for organic diversity, Phylogeny and ontogeny, species concept, mechanism of evolution, modem concept of natural selection, evolutionary trends.

Part - E

Ecology : Concept of ecosystem, biogeochemical cycles, animal adaptations to major habitats, environmental pollution and its effect on life.
