Biological Science (BIOS)
3 units: Diversity of Living Organisms, Structural Organisation in Plants and Animals, Cell Structure and Functions.
Detailed syllabus
Unit 1: Diversity of Living Organisms (19 hours, 8 marks)
The living world (biodiversity, need for classification, three domains of life, taxonomy and systematics, species, taxonomic hierarchy, binomial nomenclature, museums, zoological and botanical gardens, herbaria); biological classification (five kingdoms, Monera, Protista, Fungi, lichens, viruses, viroids, prions); plant kingdom (algae, bryophytes, pteridophytes, gymnosperms); animal kingdom (non-chordates up to phyla, chordates up to classes).
Unit 2: Structural Organisation in Plants and Animals (16 hours, 12 marks)
Morphology of flowering plants (root, stem, leaf, inflorescence, flower, fruit, seed; families Malvaceae, Solanaceae, Brassicaceae, Compositae, Leguminosae, Poaceae, Liliaceae); anatomy of flowering plants (tissue systems in dicots and monocots); animal tissues and the digestive, circulatory, respiratory, nervous and reproductive systems of the frog.
Unit 3: Cell Structure and Functions (20 hours, 15 marks)
Cell theory, prokaryotic and eukaryotic cells, plant and animal cells, cell envelope, membrane and wall, cell organelles and their ultrastructure; biomolecules (proteins, carbohydrates, lipids, nucleic acids, enzymes); cell cycle, mitosis and meiosis.
