NSEB Plant Physiology Syllabus 2026, Download PDF
Plant Physiology is an important section of the National Standard Examination in Biology (NSEB) 2026 that evaluates a candidate's understanding of the processes responsible for plant functioning.
The questions in this section test both conceptual knowledge and the ability to apply biological principles to objective and analytical problems. Candidates should prepare this unit thoroughly, as it covers several fundamental topics that frequently appear in the NSEB examination.

Transport in Plants |
Movement of water, gases and nutrients; cell to cell transport; diffusion, facilitated diffusion, active transport; plant-water relations, imbibition, water potential, osmosis, plasmolysis; long distance transport of water – absorption, apoplast, symplast, transpiration pull, root pressure and guttation; transpiration; opening and closing of stomata; uptake and translocation of mineral nutrients; transport of food; phloem transport; mass flow hypothesis. |
|
Mineral Nutrition |
Essential minerals; macro- and micronutrients and their role; deficiency symptoms; mineral toxicity; elementary idea of hydroponics as a method to study mineral nutrition; nitrogen metabolism; nitrogen cycle; biological nitrogen fixation. |
|
Photosynthesis and Respiration in Higher Plants |
Photosynthesis as a means of autotrophic nutrition; site of photosynthesis; pigments involved in photosynthesis (elementary idea); photochemical and biosynthetic phases of photosynthesis; cyclic and non-cyclic photophosphorylation; chemiosmotic hypothesis; photorespiration; C3 and C4 pathways; factors affecting photosynthesis; exchange of gases. |
|
Plant Growth and Development |
Seed germination; phases of plant growth and plant growth rate; conditions of growth; differentiation, dedifferentiation and redifferentiation; sequence of developmental processes in a plant cell; growth regulators; seed dormancy; vernalisation; photoperiodism. |

How to Prepare the NSEB Plant Physiology Syllabus 2026
Plant Physiology is a concept-intensive section that requires a clear understanding of biological processes rather than rote memorisation. Regular revision and practice of conceptual questions can help improve accuracy in this unit.
1. Prepare Fundamental Concepts
Focus on understanding processes such as water transport, mineral uptake, photosynthesis, respiration, and plant growth regulation before moving to advanced questions.
2. Learn Flowcharts and Biological Processes
Prepare diagrams and flowcharts for topics like the nitrogen cycle, mass flow hypothesis, C3 and C4 pathways, and photosynthesis to improve retention.
3. Practice Concept-Based MCQs
Solve previous NSEB-level objective questions to strengthen conceptual application and improve problem-solving speed.
4. Revise Plant Physiology Regularly
Create short notes covering important definitions, plant hormones, transport mechanisms, nutrient deficiencies, and photosynthetic pathways for quick revision.
5. Focus on Frequently Tested Topics
Give extra attention to transport in plants, photosynthesis, plant growth regulators, nitrogen fixation, and water relations, as these topics are commonly asked in NSEB.
