Hello!

We can provide you with a detailed answer only when you are specific about the question. Reduced syllabus for 11th / 12th / NEET.

I am assuming that you are asking for class 12:

1) Reproduction in organism - 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.

2) 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.

3) Strategies for enhancement in food production - Animal husbandry, Plant breeding, tissue culture, single cell protein.

4) 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).

5) 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;  exemplifying  case study as a success story addressing environmental issue(s).

ALL THE BEST. Hope the answer was of some help.

Thank You
