The HSC/12th Syllabus of Biology on which the question paper is based of Gujarat Secondary and Higher Secondary Education Board is as follows:


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 the 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 the movement of guard cells.
-Mineral absorption - functions of mineral elements; essential major elements and trace elements; deficiency symptoms of elements; theories
of translocation; translocation of solutes; Nitrogen metabolism, Nitrogen metabolism with emphasis on biological nitrogen fixation.
-Photosynthesis - significance; site of photosynthesis (functional importance of chlorophyll structure) Photochemical and biosynthetic phases.
Electron transport system;
-Photophosphorylation (cyclic and noncyclic)
C3 and C4 metabolic pathway; photorespiration, factors affecting - photosynthesis; mode of nutrition (Autotrophic, heterotrophic, saprophytic,
parasitic and insectivorous plants) chemosynthetic nutrition.


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, the formation of fecal matter, defecation)
(Intracellular and extracellular); the role of enzymes and hormones in digestion
-Malnutrition and undernutrition; disorder related to nutrition. Gaseous exchange in animals (Earthworm, Cockroach)
- Respiration in humans; respiratory organs; mechanism of respiration.
- Breathing and it's regulation; transport of gases through blood; common respiratory disorders, prevention, and cure.
Circulation of body Fluids - Open circulatory system in cockroach; closed circulatory system in humans; Blood and its composition and beating
process; pulmonary and systemic circulation; Heartbeat and pulse; rhythmicity of heart, beat.
Blood-related disorders - Hypertension, atheroma, and arteriosclerosis; ECG - Pacemaker; lymphatic system; immunity, immune system
-Elimination of nitrogenous excretory substances - Ammonotelism, Ureotelism, Urecotelism Excretory system of cockroach and humans
Composition and formation of urine
- Role of the kidney in osmoregulation, Kidney failure; dialysis, Kidney-transplantation, Role of ADH, the role of skin and lungs.
Locomotion and movements –


Reproduction, Growth, and Development

Modes of reproduction in flowering plants; vegetative propagation (natural and artificial); significance of vegetative progagation; sexual
reproduction; development of. male and female gametophyte, Pollination (types and factors); Double fertilization, incompatibility, embryo
development, parthenogenesis and parthenocarpy.
-Characters of plant growth, growth regulators (phytohormones) Auxins, Gibberellins, Cytokinins, ethylene, ABA, Seed germination -
mechanism and factors; role of growth regulators in domancy of seeds; senescence, abscission. Plant movement, geotropism, phototropism,
turgor growth movements, (tropics, nastic, and nutation) Flowering, Photoperiodism, -Vernalization
-Sexual and asexual reproduction in animals in general. Male and female reproductive system of humans; reproductive cycle in human,
oogenesis, fertilization - physical and chemical events.
Embryonic development up to three germinal layers and their derivatives Embryonic membranes, General aspect of placenta
-Cellular growth Growth rate, growth map, growth - regulation and hormones; Mechanism and types of- regeneration. Ageing - cellular and
extra cellular changes;principles of ageing.


Ecology and Environment

-Organism and their environment; factors - Air, Water, Soil, temperature, light, biota; range of tolerance; ecological adaptations
-Levels of organisation - Structure and functions, productivity, energy flow, ecological efficiencies; decomposition and nutrient cycling; major biomes - forests, grass lands and deserts.
ecological succession - types and mechanism; Natural resources types and resources. Environment pollution - kinds, sources and abatement of air, water soil and noise pollution
-Global environmental changes, green-house effects; global warming; sea level rise and ozone layer depletion. Living resources
- Terrestrial, marine and other aquatic resources; biodiversity - benefits and evaluation, threats.
Endangered species, extinctions, conservation of biodiversity (biosphere reserves and other protected areas) National and international efforts
both governmental and non-governmental; environmental ethics and legislation.
-Population, environment and development; Population growth and factors (Vitality, mortality, immigration, emigration, age and sex ratio)
-Impact of population growth; Reproductive health; common problems of adolescence; social and moral implications; mental and addictive
disorders; population as a resource.
-Food production, Hybridization, improved varieties, biofertilizers plant tissue culture and its applications; crop and animal diseases;
biopesticides; genetically modified food; biowar; biopiracy, biopatent, biotechnology and sustainable agriculture.
-Recent research in vaccines, organ transplantation, immune disorders; modern techniques in diseases diagnosis; AIDS, STD, Cancer (types,
causes, diagnosis, remedy) Biotechnology in therapeutics - hormones, interferon and immuno modulations.
