Area of Concentration for Biology JAMB 2025
The Joint Admissions and Matriculation Board (JAMB) exam is a major milestone for students hoping to gain admission into Nigerian universities and other higher institutions. Biology, as one of the core science subjects, plays a big role and it can make a real difference in your total score.
That is why proper preparation is key, and that’s where our JAMB 2025 Biology Areas of Concentration guide comes in!
In this guide, we have outlined the most important topics and concepts you should focus on to confidently tackle the Biology section of the exam. Whether you are just starting your JAMB journey or you’ve been studying for a while, this guide will help you stay on track and study smart.
So, if you are aiming to boost your JAMB score and make your Biology preparation easier, keep reading. Below are the key topics and areas of concentration for the 2025 JAMB Biology exam:
Sure! Let me act like a passionate Nigerian Biology teacher and explain each of the JAMB 2025 Biology topics in a way that’s simple, clear, and exam-focused.
SECTION A: Variety of Organisms
1. Living Organisms: These are all the things that show the characteristics of life like movement, respiration, growth, reproduction, excretion, nutrition, and sensitivity. You’ll study how both plants and animals show these traits.
2. Evolution Among the Following: Here, you wil look at how organisms have changed over time. You’ll compare groups like:
- Monera (e.g., bacteria),
- Protista (e.g., amoeba),
- Fungi (e.g., mushrooms),
- Plantae (plants), and
- Animalia (animals).
This helps you understand how complex life evolved from simple forms.
3. Structural, Functional, and Behavioural Adaptations of Organisms: Organisms adapt to survive. For example:
- Structural: Cactus has thick stems to store water.
- Functional: Frogs can breathe through their skin.
- Behavioural: Nocturnal animals come out at night to avoid predators.
SECTION B: Form and Functions
1. Internal Structure of Plants and Animals: Study the inside parts of both plants (like xylem, phloem) and animals (like organs and tissues) to understand how their bodies work.
2. Nutrition: Learn how organisms get their food:
- Autotrophs (e.g., green plants) make their own food via photosynthesis.
- Heterotrophs (e.g., humans, animals) eat other organisms.
3. Transport: How substances like water, nutrients, and oxygen move in plants (through xylem and phloem) and in animals (via blood and the circulatory system).
4. Respiration: Breaking down food to release energy. Know the difference between aerobic (with oxygen) and anaerobic (without oxygen) respiration.
5. Excretion: Removal of waste products from the body. E.g., kidneys remove urea in humans, stomata release water vapor in plants.
6. Support and Movement: How organisms hold their body and move. In plants: cell wall and stem. In animals: skeleton and muscles.
7. Reproduction: How organisms give rise to new ones — either sexually (involving male and female) or asexually (from one parent, like in amoeba).
8. Growth: Increase in size and number of cells. It’s a result of nutrition and cell division.
9. Co-ordination and Control: How organisms respond to changes. In humans, the nervous system (brain, spinal cord) and hormones control this. In plants, hormones like auxins help with response.
SECTION C: Ecology
1. Factors Affecting the Distribution of Organisms: Things like light, temperature, soil, water, and competition influence where organisms live.
2. Symbiotic Interactions of Plants and Animals: Living relationships between organisms, like:
- Mutualism (both benefit) – e.g., bee and flower,
- Parasitism (one benefits, one is harmed) – e.g., tick on a dog,
- Commensalism (one benefits, the other is not affected) – e.g., remora and shark.
3. Natural Habitats: Types of environments organisms live in — like forest, desert, swamp, river, etc.
4. Local (Nigerian) Biomes: These are large ecosystems in Nigeria — like savannah, rainforest, mangrove swamp. You must know their features and examples of organisms found in each.
5. The Ecology of Populations: Study how populations (groups of the same species) grow, interact, and survive in an environment.
6. Soil: Understand the types of soil (sand, loam, clay), their properties, and how they support plant life.
7. Humans and Environment: How human activities like pollution, deforestation, and urbanization affect the environment and what we can do to manage it responsibly.
SECTION D: Heredity and Variations
1. Variation in Population: These are the differences among individuals of the same species. Can be:
- Continuous (e.g., height, skin color),
- Discontinuous (e.g., blood group, tongue rolling).
2. Heredity: Passing of traits from parents to offspring. You’ll learn about genes, chromosomes, dominant and recessive traits, and simple Mendelian genetics.
SECTION E: Evolution
1. Theories of Evolution: You will explore major ideas explaining how life evolved. For example:
- Darwin’s Theory of natural selection,
- Lamarck’s Theory of use and disuse.
2. Evidence of Evolution: Clues that support evolution like:
- Fossils,
- Comparative anatomy,
- Embryology,
- DNA similarities.
