TundeAre you sitting for the upcoming JAMB UTME exam and searching for the JAMB biology syllabus 2026/2027? Search no more, here at masterjamb.com we have shared with you the updated JAMB syllabus for biology including the areas of concentration and recommended textbooks.
Biology is one of the most important subjects in JAMB 2026, especially for candidates willing to study Medicine, Nursing, Pharmacy, Agriculture, Environmental Science, and other science-related courses.
The only smart way to prepare is by studying with the official JAMB Biology syllabus. This syllabus is compulsory because every Biology question set in the CBT exam is drawn strictly from it. Reading outside the syllabus wastes time and often leads to poor results.
JAMB biology syllabus 2026 cover topics like: living organisms, ecology, heredity and variation, evolution, structural/functional and behavioural adaptations of organisms, internal structure of plants and animals, nutrition, transport, support and movement, etc.
Is the JAMB Biology Syllabus 2026 Officially Out?
Yes, The JAMB Biology syllabus for 2026 is officially out, as JAMB operates with a stable syllabus structure that is used every year, with only minor updates when necessary.
Overview of JAMB Biology Syllabus 2026
The JAMB Biology syllabus 2026 is carefully designed to test candidates understanding of biological concepts, their ability to apply these concepts, and how well they can relate Biology to everyday life. The general objectives of the syllabus are to ensure that candidates can demonstrate clear knowledge of the diversity, unity, and interdependence of living organisms, explain the continuity of life through reproduction, heredity, and evolution, and apply biological principles to issues affecting health, environment, agriculture, and the economy.
In the UTME, JAMB does not test memorization alone. Candidates are assessed on knowledge of facts and concepts, application of biological principles, and the ability to interpret biological processes in real life situations such as disease control, nutrition, environmental conservation, and human health. This is why understanding, not cramming, is strongly emphasized.
The JAMB Biology syllabus is structured into five major sections (A–E):
- Section A: Variety of Organisms
- Section B: Form and Functions
- Section C: Ecology
- Section D: Heredity and Variations
- Section E: Evolution
Each section covers specific topics that form the basis of all Biology questions asked in the JAMB CBT examination.
JAMB Biology Syllabus 2026
SECTION A: Variety of Organisms
This section introduces candidates to the basic features and diversity of living things. It forms the foundation of JAMB Biology and helps students understand how organisms are classified, structured, and adapted to their environment. Below are topics covered:
- Characteristics of living organisms and how they differ from non-living things
- Cell structure and functions, including plant and animal cells
- Levels of organization from cell → tissue → organ → system → organism
- Evolution and classification of organisms, including:
- Monera, Protista, and Fungi
- Plantae (Thallophyta, Bryophyta, Pteridophyta, Gymnosperms, Angiosperms)
- Animalia (Invertebrates and Vertebrates)
- Structural, functional, and behavioural adaptations of organisms to their habitats
JAMB frequently tests classification features, adaptive characteristics, and simple biological diagrams in this section. Candidates should also understand the economic importance of plants and animals, as well as how adaptations help organisms survive in different environments.
SECTION B: Form and Functions
This is one of the most important and widest sections of the JAMB Biology syllabus. It focuses on how the structures of living organisms enable them to perform vital life functions. Below are topics covered:
- Internal structure of plants (root, stem, and leaf)
- Internal structure of mammals
- Nutrition:
- Plant nutrition (photosynthesis, mineral requirements)
- Animal nutrition (classes of food, digestive enzymes, digestion and absorption)
- Transport systems (blood circulation in mammals, xylem and phloem in plants)
- Respiration (aerobic and anaerobic respiration)
- Excretion and excretory organs
- Support and movement in plants and animals
- Reproduction in plants and mammals
- Growth and germination
- Coordination and control (nervous and hormonal systems)
- Homeostasis and internal body balance
Questions from this section often test biological processes, functions of organs, food tests, and basic physiology. Candidates should pay attention to step-by-step processes, definitions, and relationships between structure and function, as these are commonly examined in the CBT.
SECTION C: Ecology
This section deals with the relationship between living organisms and their environment. It emphasizes how environmental factors influence the distribution, survival, and interaction of plants and animals, with strong focus on real-life and Nigerian examples. Below are topics covered:
- Factors affecting the distribution of organisms (biotic and abiotic factors)
- Symbiotic relationships such as mutualism, parasitism, commensalism, and competition
- Energy flow and nutrient cycles, including food chains, food webs, carbon cycle, nitrogen cycle, and water cycle
- Natural habitats, both aquatic and terrestrial
- Nigerian biomes, including rainforest, savanna, desert, and highland regions
- Population ecology (population size, density, competition, and succession)
- Soil: types, fertility, erosion, and conservation methods
- Humans and the environment, covering diseases, sanitation, pollution, and conservation of natural resources
JAMB often tests ecology diagrams, food chains/webs, nutrient cycles, and environment-related questions. Candidates should understand Nigeria-based environmental examples, common diseases, methods of disease control, pollution types, and conservation practices.
SECTION D: Heredity and Variations
This section explains how traits are passed from parents to offspring and why differences exist among individuals within a population. It is one of the most scoring sections when properly understood.
- Variation in populations (morphological and physiological variations)
- Continuous and discontinuous variation
- Blood groups and fingerprints
- Chromosomes and DNA as the basis of heredity
- Mendelian genetics and inheritance patterns
- Sex-linked traits such as colour blindness and haemophilia
- Applications of heredity in agriculture, medicine, and marriage counselling
Questions from this section usually involve genetics calculations, definitions, and simple inheritance patterns. JAMB also tests real-life applications, including blood transfusion, paternity determination, disease prevention, and selective breeding in agriculture.
SECTION E: Evolution
This section explains how living organisms have changed and diversified over long periods of time. It helps candidates understand the origin of life, adaptation, and the gradual development of plants and animals. Below are topics covered:
- Theories of evolution, including:
- Lamarck’s theory of acquired characteristics
- Darwin’s theory of natural selection
- Evidence of evolution, such as fossil records, comparative anatomy, physiology, and embryology
- Evolutionary trends in plants and animals, showing increasing complexity
- Modern evolutionary theories, including genetic studies and the role of mutation
JAMB often sets questions that require comparison of evolutionary theories, identification of evidence supporting evolution, and understanding how organisms adapt over time. Candidates should focus on clear definitions, differences between theories, and practical examples.
