All the details for WAEC Biology Practical Specimens 2025 (May/June): Updated & Verified List can be found here on TJ News Nigeria.
The West African Examinations Council (WAEC) has officially released the 2025 Biology Practical Specimens for the May/June West African Senior School Certificate Examination (WASSCE). These specimens are essential for the practical aspect of Biology and will be used during the actual examination.
This article provides a detailed description of each of the WAEC 2025 Biology Practical Specimens, helping candidates understand their physical characteristics, scientific relevance, and how to handle them during the exam.
Why the WAEC Biology Practical Specimens Matter
Biology practicals test students’ observational, analytical, and experimental skills. With questions based directly on physical specimens, understanding what you are handling is vital to scoring high.
Confirmed WAEC Biology Practical Specimens 2025
Each candidate sitting for the Biology practical is expected to be familiar with the following materials, labeled accordingly:
- Specimen A: Bean Weevil
- Specimen B: Bean Seeds (with holes)
- Specimen C: Waterleaf Plant (whole)
- Specimen D: Quill Feather of a Domestic Fowl
- Specimen E: Pineapple Fruit (longitudinal section)
- Specimen F: Orange Fruit (transverse section)
- Specimen G: Raw Egg of a Domestic Fowl (with shell)
- Specimen H: Test Tube with 3 ml of Water
- Specimen J: Longitudinal Section of Boiled Egg (with shell)
Detailed Descriptions and Importance of Each Specimen
Specimen A: Bean Weevil
- Scientific Classification: Insect pest (Callosobruchus maculatus)
- Description: Small, oval-bodied insect found in stored beans.
- Use in Exam: Used to demonstrate pest infestation and its impact on food preservation.
Specimen B: Bean Seeds (with Holes)
- Observation: Boreholes caused by bean weevil larvae.
- Educational Value: Shows storage damage; used in teaching pest control and food security.
Specimen C: Waterleaf Plant
- Scientific Name: Talinum triangulare
- Parts Visible: Root, stem, leaf (entire plant structure)
- Exam Use: Helps in identifying vegetative parts and plant morphology.
Specimen D: Quill Feather
- Source: Domestic fowl (chicken)
- Parts: Rachis, barbs, barbules
- Relevance: Demonstrates structural adaptations in birds and thermoregulation.
Specimen E: Pineapple (Longitudinal Section)
- Type: Multiple fruit
- Observations: Fruitlets, fibrous core, skin
- Use: Understanding compound fruits, fruit formation, and morphology.
Specimen F: Orange (Transverse Section)
- Fruit Type: Hesperidium
- Features: Juice sacs, central core, seeds
- Relevance: Study of fruit anatomy and placentation in dicots.
Specimen G: Raw Egg (Domestic Fowl)
- Observation: Shell, yolk, albumen
- Relevance: Studies in animal reproduction, development, and structure of an ovum.
Specimen H: Test Tube with Water
- Volume: 3 ml
- Tool Function: For performing food tests (glucose, starch, protein)
- Lab Relevance: Reinforces laboratory techniques and handling skills.
Specimen J: Boiled Egg (Longitudinal Section)
- Observation: Yolk centered, hardened white
- Use: Demonstrates heat effects on biological tissue and internal egg structure.
How to Prepare for the Biology Practical Examination
Follow these tested strategies to perform well:
1. Study the Specimens Thoroughly
- Know their structure, function, and biological significance.
- Learn to label diagrams and identify parts accurately.
2. Practice Drawing and Labeling
- Neat and well-labeled diagrams score high.
- Focus on features like feather structures, fruits’ internal arrangements, and animal organs.
3. Understand Food Tests
- Common practicals include tests for starch (iodine), glucose (Benedict’s), and protein (biuret).
- Use the test tube specimen (H) appropriately under examiner’s instruction.
4. Revise Animal and Plant Morphology
- Most specimens relate to topics on anatomy, reproduction, and pest biology.
- Revise plant systems and storage pests.

WAEC Practical Exam Tips
- Read all instructions carefully before handling any specimen.
- Avoid contamination or damage to samples.
- Use appropriate terminologies (e.g., rachis, hilum, pericarp) in answers.
- Manage your time wisely – don’t spend too long on drawings.
Final Notes
WAEC has warned that schools and supervisors must prevent any leakage of these specimen details to candidates before the exam. However, publishing this article is for educational and preparatory purposes only.
