As the regular teaching-learning  in schools, during the session 2020-21, has widely been affected due to the COVID-19 pandemic, the subject experts committee, after due consideration, has recommended to reduce the syllabus by 30% in the following manner:-

Unit-VI Reproduction:

Chapter-1: Reproduction in Organisms

Reproduction, a characteristic feature of all organisms for continuation of species; modes of reproduction - asexual and sexual reproduction; asexual reproduction - binary fission, sporulation, budding, gemmule formation, fragmentation; vegetative propagation in plants.

Unit-VII Genetics and Evolution

Chapter-7: Evolution

Origin  of life;  biological  evolution  and  evidences  for biological  evolution  (paleontology, comparative anatomy, embryology and molecular evidences); Darwin's contribution, modern synthetic   theory   of   evolution;   mechanism   of   evolution   -   variation   (mutation   and recombination)  and natural selection with examples, types of natural selection; Gene flow and genetic drift; Hardy - Weinberg's principle; adaptive radiation; human evolution.

Unit-VIII Biology and Human Welfare

Chapter-9: Strategies for Enhancement in Food Production

Improvement   in  food  production:   Plant  breeding,   tissue  culture,   single  cell  protein, Biofortification, Apiculture and Animal husbandry.

Unit-X Ecology and Environment

Chapter-14: Ecosystem

Ecosystems: Patterns, components; productivity and decomposition;  energy flow; pyramids of   number,   biomass,   energy;   nutrient   cycles   (carbon   and   phosphorous); ecological succession; ecological services - carbon fixation, pollination, seed dispersal, oxygen release

(in brief).

Chapter-16: Environmental Issues

Air pollution and its control; water pollution and its control; agrochemicals and their effects; solid  waste  management;  radioactive  waste  management;  greenhouse  effect  and  climate change impact and mitigation; ozone layer depletion; deforestation;  any one case study as success story addressing environmental issue(s).

Reduced Practicals:

 

A. List of Experiments

1. Study the presence of suspended particulate matter in air at two widely different sites.

2. Study the plant population frequency by quadrat method.

3. Study the plant population density by quadrat method

B. Study/observation of the following (Spotting)

1. Pollen germination on stigma through a permanent slide.

2. Mendelian inheritance using seeds of different colour/sizes of any plant.

3. Controlled pollination - emasculation, tagging and bagging.

 

In accordance to the above, the remaining 70 percent of the total syllabus is as follows:

Unit-VI Reproduction (14 marks)

Chapter-2: Sexual Reproduction in Flowering Plants

Flower  structure;  development  of  male  and  female  gametophytes;  pollination  -  types, agencies  and examples;  outbreeding  devices;  pollen-pistil  interaction;  double  fertilization; post fertilization events - development of endosperm and embryo, development of seed and formation  of fruit; special  modesapomixis,  parthenocarpy,  polyembryony;  Significance  of seed dispersal and fruit formation.

Chapter-3: Human Reproduction

Male   and   female   reproductive   systems;   microscopic   anatomy   of   testis   and   ovary; gametogenesis - spermatogenesis and oogenesis; menstrual cycle; fertilisation, embryo development upto blastocyst formation, implantation; pregnancy and placenta formation (elementary idea); parturition (elementary idea); lactation (elementary idea).

Chapter-4: Reproductive Health

Need for reproductive health and prevention of Sexually Transmitted Diseases (STDs); birth control  - need and methods,  contraception  and medical  termination  of pregnancy  (MTP); amniocentesis;   infertility   and   assisted   reproductive   technologies   -  IVF,   ZIFT,   GIFT (elementary idea for general awareness).

Unit-VII Genetics and Evolution  

Chapter-5: Principles of Inheritance and Variation

Heredity and variation: Mendelian inheritance; deviations from Mendelism – incomplete dominance, co- dominance, multiple alleles and inheritance of blood groups, pleiotropy; elementary idea of polygenic inheritance; chromosome theory of inheritance; chromosomes and genes; Sex determination - in humans, birds and honey bee; linkage and crossing over; sex linked  inheritance  - haemophilia,  colour  blindness;  Mendelian  disorders  in humans  - thalassemia; chromosomal disorders in humans; Down's syndrome, Turner's and Klinefelter's syndromes.

Chapter-6: Molecular Basis of Inheritance

Search for genetic material and DNA as genetic material; Structure of DNA and RNA; DNA packaging;  DNA replication;  Central dogma;  transcription,  genetic  code, translation;  gene expression and regulation - lac operon; genome and human and rice genome projects; DNA fingerprinting.

Unit-VIII Biology and Human Welfare 

Chapter-8: Human Health and Diseases

Pathogens; parasites causing human diseases (malaria, dengue, chickengunia, filariasis, ascariasis,  typhoid,  pneumonia,  common  cold,  amoebiasis,  ring  worm)  and  their  control; Basic concepts of immunology - vaccines; cancer, HIV and AIDS; Adolescence - drug and alcohol abuse.

Chapter-10: Microbes in Human Welfare

In household food processing, industrial production, sewage treatment, energy generation and microbes as bio-control agents and bio-fertilizers. Antibiotics; production and judicious use.

Unit-IX Biotechnology and Its Applications

Chapter-11: Biotechnology - Principles and processes Genetic Engineering (Recombinant DNA Technology). 

Chapter-12: Biotechnology and its Application

Application   of  biotechnology   in  health  and  agriculture:   Human   insulin   and  vaccine

production, stem cell technology, gene therapy; genetically modified organisms - Bt crops;

transgenic animals; biosafety issues, bio piracy and patents.

Unit-X Ecology and Environment  

Chapter-13: Organisms and Populations

Organisms  and  environment:  Habitat  and  niche,  population  and  ecological  adaptations;

population interactions - mutualism, competition, predation, parasitism; population attributes

- growth, birth rate and death rate, age distribution.

Chapter-15: Biodiversity and its Conservation

Biodiversity-Concept,  patterns,  importance;  loss of biodiversity;  biodiversity  conservation; hotspots,  endangered  organisms,  extinction,  Red  Data  Book,  biosphere  reserves,  national parks, sanctuaries.

Practicals: 30 marks
