relationship of various phyla up to subclasses: Acoelomate and Coelomate,
Protostomes and Deuterostomes, Bilateria and Radiata; Status of Protista,
Parazoa, Onychophora and Hemichordata; Symmetry. (b) Protozoa: Locomotion,
nutrition, reproduction, sex; General features and life history of Paramaecium,
Monocystis, Plasmodium and Leishmania. (c) Porifera: Skeleton, canal system and
reproduction. (d) Cnidaria: Polymorphism, defensive structures and their
mechanism; coral reefs and their formation; metagenesis; general features and
life history of Obelia and Aurelia. (e) Platyhelminthes: Parasitic adaptation;
general features and life history of Fasciola and Taenia and their pathogenic
symptoms. (f) Nemathelminthes: General features, life history, parasitic
adaptation of Ascaris and Wuchereria. (g) Annelida: Coelom and metamerism; modes
of life in polychaetes; general features and life history of Nereis, earthworm
and leach. (h) Arthropoda: Larval forms and parasitism in Crustacea; vision and
respiration in arthropods (Prawn, cockroach and scorpion); modification of mouth
parts in insects (cockroach, mosquito, housefly, honey bee and butterfly);
metamorphosis in insect and its hormonal regulation, social behaviour of Apis
and termites.
(i) Mollusca: Feeding, respiration, locomotion, general
features and life history of Lamellidens, Pila and Sepia, torsion and detorsion
in gastropods. (j) Echinodermata: Feeding, respiration, locomotion, larval
forms, general features and life history of Asterias. (k) Protochordata: Origin

skull types, status of Sphenodon and crocodiles. (o) Aves: Origin of birds,
flight adaptation, migration. (p) Mammalia: Origin of mammals, dentition,
general features of egg laying mammals, pouched-mammals, aquatic mammals and
primates, endocrine glands (pituitary, thyroid, parathyroid, adrenal, pancreas,
gonads) and their interrelationships. (q) Comparative functional anatomy of
various systems of vertebrates (integument and its derivatives, endoskeleton,
locomotory organs, digestive system, respiratory system, circulatory system
including heart and aortic arches, urino-genital system, brain and sense organs
(eye and ear).
2. Ecology: (a) Biosphere: Concept of biosphere;

green house effect, ecological succession, biomes and ecotones, community
ecology. (b) Concept of ecosystem; structure and function of ecosystem, types of
ecosystem, ecological succession, ecological adaptation. (c) Population;
characteristics, population dynamics, population stabilization. (d) Biodiversity
