Unit II. Plant Physiology

  1. Water Relations of Plants: Water availability in soil; water potential; movement of water:
    diffusion, osmosis; transport of water in plants: absorption by roots, root to shoot transport,
    transpiration (mechanism and factors affecting transpiration), cohesion-tension theory of ascent of
    sap; water stress: effects and plants‟ response.
  1. Plant Nutrients: Nutrient availability in soil; nutrient absorption by root; macro and
    micronutrients: roles in plant and symptoms of deficiencies; hydroponics.
  2. Plant Development: Growth and differentiation; Tissue culture and organogenesis; Polarity;
    Photomorphogenesis; Photoperiodism; Seed physiology: Seed germination and mobilization of
    reserved food, seed dormancy, vernalization; senescence.
  3. Plant Hormones: Concept of hormone; physiological roles of auxins, gibberellins, cytokinnins,
    ethylene, abscissic acid, and brassinosteroids; commercial uses of plant hormones.
  4. Metabolism: Anabolism and Catabolism; Photosynthesis: Radiant energy, ultrastructure of
    chloroplast, photosynthetic pigments, mechanisms (light reaction, and dark reaction/CO2
    assimilation – C3, C4 and CAM), factors affecting photosynthesis; photorespiration; respiration:
    ultrastructure of mitochondria, anaerobic and aerobic respiration, glycolysis, Kreb‟s cycle,
    respiratory chain; chemiosmotic mechanism of ATP synthesis.

Unit III. Cytology and Genetics

  1. Cytology: structural organization of prokaryotic and eukaryotic cells; Ultrastructure and function
    of cell organelles; cell inclusions; physical and chemical nature of chromosomes; cell division:
    cell cycle, karyokinesis (amitosis, mitosis and meiosis) and cytokinesis.
  2. Genetics: Physical structure, type and functions of nucleic acids (DNA and RNA); DNA
    replication; gene structure, gene expression and regulation in prokaryotes and eukaryotes.
    Mendelian genetics: Mendel‟s laws of inheritance, gene interactions (incomplete dominance, codominance, epistasis), linkage and crossing over, sex linked inheritance. Sources of genetic
    variation: gene and chromosomal mutation (chromosomal aberrations, euploidy, aneuploidy and
    polyploidy). Concept of plant breeding (hybridization).

Unit IV. Embryology

  1. Structure and development of microsporangium, microsporogenesis and the male gametophyte;
    structure and development of megasporangium, megasporogenesis and the female gametophyte;
    pollination and fertilization; development and types of endosperm; embryogenesis in typical dicot
    and monocot plants; polyembryony; apomixes; experimental embryology; palynology:
    introduction and its scope.

Unit V. Plant anatomy

  1. Tissues and tissue system: structure and functions of meristematic and permanent tissues (simple,
    complex and special tissues); shoot apical meristem (histological organizations in monocot and
    dicot stem); root apical meristem (histological organization in monocot and dicot root); theories
    of apical meristem differentiation.
  1. Primary structures and functions: epidermis: uniseriate and multiseriate, epidermal appendages
    and their morphological types; primary structure of typical dicot stem, root and leaf; primary
    structure of typical monocot stem, root and leaf; cambium: origin, structure and functions.
  2. Secondary structures and functions: Origin and structure of secondary xylem and phloem;
    secondary growth in dicot stem and root; anomalous secondary growth (dicot- Boerhaavia,
    Nyctanthes and Achyranthes; monocot- Dracaena); annual and growth rings; dendrochronology
    (concept and application); heart wood and sapwood; periderm; wound healing; leaf abscission;
    nodal anatomy; floral anatomy.
