Biology (Zoology) flashcards for SRMJEEE

22 of 74 cards from the Biology (Zoology) deck — real questions with worked answers.

1. What are the five kingdoms in Whittaker's classification of living organisms?

   Monera, Protista, Fungi, Plantae, and Animalia.

2. List the levels of the taxonomic hierarchy from broadest to most specific.

   Kingdom, Phylum, Class, Order, Family, Genus, Species.

3. What is the basis of classification of the animal kingdom (key criteria used)?

   Levels of organisation, symmetry, germ layers (diploblastic/triploblastic), presence/nature of coelom, segmentation, and presence of a notochord.

4. Distinguish diploblastic from triploblastic animals.

   Diploblastic animals have two germ layers (ectoderm and endoderm) e.g. cnidarians; triploblastic animals have three (ectoderm, mesoderm, endoderm) e.g. from platyhelminthes onwards.

5. Define a coelom and name the three coelomic conditions.

   A coelom is a true body cavity lined by mesoderm. Conditions: acoelomate (no cavity), pseudocoelomate (cavity not fully mesoderm-lined), and coelomate (true mesoderm-lined cavity).

6. Compare radial and bilateral symmetry with examples.

   Radial symmetry: body can be divided into equal halves through any plane passing through the centre (e.g. cnidarians, echinoderms). Bilateral symmetry: only one plane divides the body into identical left and right halves (e.g. annelids, arthropods, chordates).

7. What are the defining features of the phylum Porifera?

   Pore-bearing aquatic animals (sponges); cellular level of organisation; water canal (canal) system with ostia and osculum; choanocytes (collar cells); spicules/spongin skeleton.

8. Name the three classes of the phylum Cnidaria with an example of each.

   Hydrozoa (Hydra, Obelia), Scyphozoa (Aurelia, jellyfish), Anthozoa (Adamsia, sea anemone, corals).

9. What unique cells do cnidarians possess and what is their function?

   Cnidoblasts (cnidocytes) containing nematocysts, used for anchorage, defence, and capturing prey (stinging).

10. What are the key characters of phylum Platyhelminthes?

    Dorsoventrally flattened (flatworms); triploblastic, acoelomate, bilaterally symmetrical; mostly parasitic with hooks/suckers; flame cells for excretion and osmoregulation. Example: Taenia, Fasciola.

11. What is the distinguishing feature of phylum Aschelminthes (Nematoda)?

    Roundworms that are triploblastic and pseudocoelomate, with a complete digestive tract; many are parasites. Example: Ascaris, Wuchereria.

12. List the defining features of phylum Annelida.

    Metamerically segmented body (true segmentation); triploblastic, coelomate, bilaterally symmetrical; closed circulatory system; nephridia for excretion. Example: Pheretima (earthworm), Hirudinaria (leech).

13. What features make Arthropoda the largest animal phylum?

    Jointed appendages, chitinous exoskeleton, segmented body, open circulatory system with haemocoel; respiration by gills, trachea or book lungs. Example: Periplaneta (cockroach), Apis (honeybee).

14. What are the characteristic features of phylum Mollusca?

    Soft unsegmented body with a muscular foot, visceral hump, and mantle; usually a calcareous shell; radula for feeding; open circulatory system. Example: Pila, Octopus, Unio.

15. Which features define phylum Echinodermata?

    Exclusively marine; spiny skin; radial symmetry in adults (bilateral larvae); unique water vascular system with tube feet; calcareous endoskeleton. Example: Asterias (starfish), Echinus.

16. What are the four fundamental (defining) chordate characters?

    Presence of a notochord, a dorsal hollow nerve cord, paired pharyngeal gill slits, and a post-anal tail at some stage of life.

17. Name the three subphyla of Chordata with an example of each.

    Urochordata (Ascidia/tunicates), Cephalochordata (Branchiostoma/Amphioxus), and Vertebrata (fishes to mammals).

18. How do chordates differ from non-chordates in heart, notochord, and nerve cord position?

    Chordates have a ventral heart, a notochord, and a dorsal, hollow, single nerve cord; non-chordates have a dorsal heart (if present), no notochord, and a ventral, solid, double nerve cord.

19. Distinguish the two classes of the superclass Pisces.

    Chondrichthyes have a cartilaginous endoskeleton, ventral mouth, placoid scales, and no air bladder (e.g. Scoliodon, shark); Osteichthyes have a bony endoskeleton, terminal mouth, and an air bladder (e.g. Labeo, Catla).

20. What are the distinguishing features of class Amphibia?

    Moist glandular skin without scales, usually two pairs of limbs, three-chambered heart, cold-blooded (poikilotherms), and external fertilisation with aquatic larvae. Example: Rana, Salamandra.

21. Which class of vertebrates first showed amniotic eggs, and what defines class Reptilia?

    Reptilia first showed amniotic (shelled) eggs; characterised by dry, scaly skin, creeping/crawling, three-chambered heart (four in crocodiles), and being poikilothermic. Example: Naja, Chelone.

22. What are the defining features of class Aves?

    Warm-blooded (homeothermic); body covered with feathers; forelimbs modified into wings; presence of a beak without teeth; pneumatic bones; four-chambered heart. Example: Corvus, Columba.
