CHSE Odisha Elective Biology · Work through your exam, one topic at a time.
The CHSE Odisha Elective Biology examination is the written subject paper taken by +2 (senior secondary) science students in Odisha who choose Biology as an elective. It is intended for candidates completing higher secondary schooling under the Council of Higher Secondary Education, Odisha, and for private or repeat candidates preparing for the same paper. The CHSE Odisha Elective Biology study guide has 10 sections and about 2,782 words.
01Diversity of Living Organisms
Domain 1 examines taxonomy and classification and the diversity of major plant and animal groups. The exam expects precise use of binomial nomenclature, taxonomic hierarchy and the diagnostic features that separate kingdoms, plant divisions and animal phyla.
297 words, about 1 min02Structural Organisation in Plants and Animals
Domain 2 tests plant morphology and anatomy and the four animal tissue types. Expect questions on root, stem and leaf modifications, tissue systems, vascular bundle arrangement and tissue identification.
283 words, about 1 min03Cell Structure and Function
Domain 3 covers cell structure, biomolecules and the cell cycle. Questions test organelle functions, membrane models, tests for biomolecules, enzyme action and the differences between mitosis and meiosis.
292 words, about 1 min04Plant Physiology
Domain 4 covers transport, photosynthesis, respiration and plant growth. The exam tests water potential, transpiration, phloem loading, C3 and C4 pathways, respiration stages and hormone effects.
293 words, about 1 min05Human Physiology
Domain 5 covers digestion, circulation, respiration, excretion and neural and endocrine control. Questions ask for enzyme actions, heart and nephron function, gas transport and hormone effects.
294 words, about 1 min06Reproduction
Domain 6 covers sexual reproduction in flowering plants and humans and reproductive health. Expect questions on flower structure, gametogenesis, double fertilisation, the menstrual cycle, contraception and STDs.
267 words, about 1 min07Genetics and Evolution
