BIOLOGY

Unit : 6 Physiology of Plants
-Cell as a functional unit, Composition of protoplasm; water relations; Absorption and conduction (Diffusion, osmosis, plasmolysis, permeability, water potential, absorption)
Theories of ascent of sap - root pressure, suction force transpiration - importance.
Factors affecting rate o transpiration; mechanism of stomatal opening and closing; (Potassium ion theory); factors affecting movement of guard cells.
-Mineral absorption - functions of mineral elements; essential major elements and trace elements; deficiency symphoms of elements; theories of translocation; translocation of solutes; Nitrogen metabolism, Nitrogen metabolism with emphasis on biological nitrogen fixation.
-Photosynthesis - signifcance; site of photosynthesis (functional importance of chlorophyll structure) photochemical and bio synthetic phases. Electron transport system;
Photo phosphorylation (cyclic and noncyclic)
C3 and C4 metabolic pathway; photo respiration, factors affecting - photosynthesis; mode of nutrition (Autotrophic, heterotrophic, saprophytic, parasitic and insectivorous plants) chemosynthetic nutrition.
Unit : 7 Physiology of Animals
  • Nutrition and its types; nutrients food and vitamins; digestive system of invertebrate (Cockroach)
    Digestive system and digestion process in humans (ingestion, digestion, absorption, assimilation, formation of faecal matter, defecation) (Intra cellular and extra cellular); role of enzymes and hormones in digestion.
    Malnutrition and under nutrition; disorder related to nutrition.
  • Gaseous exchange in animals (Earthworm, Cockroach)
    - Respiration in humans; respiratory organs; mechanism of respiration.
    - Breathing and its regulation; transport of gases through blood; common respiratory disorders, prevention and cure.
  • Circulation of body Fluids - Open circulatory system in coc kroach; closed circulatory system in humans; Blood and its composition and beating process; pulmonary and systemic circulation; Heart beat and pulse; rhythmicity of heart, beat.
    Blood related disorders - Hypertention, atheroma, and arteriosclerosis;
    ECG - Pace maker; lymphatic system; immunity, immune system.
  • Elimination of nitrogenous excretory substances - Amnotelism, Ureotelism, Urecotelism Excretory system of cockroach and humans Composition and formation of urine.
    - Role of kidney in osmoregulation, Kidney failure; dialysis, Kidney-transplantation, Role of ADH, role of skin and lungs.
  • Locomotion and movements -
    - Human skeleton, axial and appendicular, Cranium and cage bones; Joints and their types Bone, Cartilage and their disorders (Carthritis, osteoporosis) Mechanism of muscle contraction.
