WAEC 2026 Biology Practical Specimen Questions

by

The WAEC Biology Practical examination is one of the most important components of the West African Senior School Certificate Examination (WASSCE) as it Examines Students majorly in Practical, which includes Dissection, Drawing, observation, Identification of different animals and plants.

The WAEC Biology Specimen 2026 is a Practical HANDBOOK, for every student/Candidate.

Every year, thousands of candidates fail to score high in Biology not because they lack knowledge, but because they are not familiar with the official WAEC Biology Practical Specimen.

  • Identify biological specimens

  • Observe carefully and draw accurately

  • Describe morphology and adaptations

  • Carry out simple food tests and experiments

  • Answer practical-based questions correctly

If you are preparing seriously for WAEC Biology, this  WAEC Biology Specimen 2026 article will save you from costly mistakes and last-minute panic.

What Is theWAEC 2026 Biology Practical Specimen?

The WAEC Biology Practical Specimen refers to the actual plants, animals, parts, models, and materials that candidates will handle during the Biology practical examination.

These specimens are used for:

  • Identification

  • Observation and description

  • Drawing and labeling

  • Comparison of structures

  • Simple experiments such as food tests

They differ slightly every year, but WAEC usually selects common organisms and materials that are familiar to secondary school students.

Typical categories include:

  • Insects (weevils, butterflies, mosquitoes, ants)

  • Plant parts (leaves, seeds, flowers, fruits)

  • Animal parts (feathers, bones, eggs)

  • Prepared slides or models

  • Simple chemical reagents for food tests

Understanding these specimens early is one of the strongest strategies for scoring A or B in WAEC Biology practical.

Comparison Between Specimen A and Specimen B

Similarities:

  • Both are small in size

  • Both are hard in texture

  • Both have outer coverings

Explanation of Holes in Specimen B

  • Caused by larvae feeding inside the seed

  • Larvae hatch from eggs laid in the seed coat

  • Relationship is parasitic

Prevention of Damage to Bean Seeds

  • Airtight storage

  • Use of insecticides or fumigation

  • Freezing

  • Radiation of seeds
