- Stem
- Root
- Flower
What you must know:
- Identification: Be able to recognize each specimen by its shape, color, and structure
- Functions: Know what each part does (e.g., leaf → photosynthesis)
- Differences: Compare specimens (e.g., monocot vs dicot leaves)
B. Animal Specimens
These test your knowledge of animal structure, classification, and adaptation.
Insects: Grasshopper, cockroach
- Snail
- Fish
- Earthworm
Focus on:
- External Features: Body parts like head, thorax, abdomen, fins, shell
- Classification: Grouping animals into classes (e.g., insect, mollusk, annelid)
- Adaptations: Features that help them survive (e.g., gills in fish for breathing)
C. Microscopic Specimens
These require careful observation and sometimes drawing.
- Onion cells
- Cheek cells
- Microorganisms
You should understand:
- Slide Preparation: How specimens are placed on slides and stained
- Observation: Identifying cell parts like nucleus, cytoplasm, and cell wall
D. Laboratory Equipment
WAEC may present tools and ask about their uses.
- Microscope
- Beaker
- Test tube
- Hand lens
What to study:

- Identification: Recognizing each tool easily during the exam
WAEC questions often repeat similar specimen types every year. If you master these categories and understand their features and uses, you will find the practical exam much easier.
Detailed Answers and Explanations for Each Specimen
This is the most important section for your WAEC Biology Practical preparation. As a teacher, I always advise students to go beyond identification, you must understand what to write when a specimen is given. WAEC marking is very direct, and if your points are clear and correct, you will score high.
Use this simple structure for any specimen you see in the exam:
Example 1: Leaf (e.g., Hibiscus Leaf)
Name of Specimen: Leaf (Hibiscus leaf)
Classification: Plant (Dicotyledon)
Features:
- Broad and flat surface
- Presence of veins (reticulate venation)
- Green in color due to chlorophyll
- Has petiole (leaf stalk)
Functions:
- Photosynthesis (food production)
- Transpiration (loss of water)
- Gaseous exchange
Diagram Tips:
- Draw a neat, large outline
- Show veins clearly
- Label important parts like lamina and petiole
Students often forget to mention venation type, this is a common WAEC marking point. Always include it.
Example 2: Snail
Name of Specimen: Snail
Classification: Phylum Mollusca
Features:
- Soft body
- Hard shell for protection
- Muscular foot for movement
- Tentacles for sensing
Functions:
- Shell protects the body
- Foot helps in locomotion
- Tentacles detect environment
Diagram Tips:
- Draw the spiral shell clearly
- Label tentacles, shell, and foot
Always mention “muscular foot” WAEC frequently awards marks for that specific term.
Example 3: Fish
Name of Specimen: Fish
Classification: Class Pisces
Features:
- Streamlined body
- Presence of fins
- Gills for breathing
- Scales covering body
Functions:
- Fins for movement and balance
- Gills for respiration in water
- Scales for protection
Diagram Tips:
- Draw side view
- Label fins, gills, and scales
Do not confuse gills with lungs, this is a very common mistake.
Example 4: Onion Cells
Name of Specimen: Onion cell
Classification: Plant cell
Features:
- Rectangular shape
- Presence of cell wall
- Large vacuole
- Visible nucleus
Functions:
- Cell wall provides support
- Nucleus controls activities
- Vacuole stores substances
Diagram Tips:
- Draw brick-like shapes
- Label nucleus, cytoplasm, and cell wall
Always mention “cell wall” it is the key difference between plant and animal cells.
Example 5: Microscope
Name of Specimen: Microscope
Classification: Laboratory equipment
Features:
- Eyepiece
- Objective lenses
- Stage
- Mirror or light source
Functions:
- Used to magnify tiny objects
- Helps in observing cells and microorganisms
Diagram Tips:
- Draw upright structure
- Label eyepiece, stage, and base
Many students only write “used for viewing objects” this is too vague. Always say “magnify tiny objects” for full marks.
Final Teacher Advice
- Always follow the same answering pattern in the exam
- Use correct biological terms
- Keep answers short, clear, and straight to the point
- Practice writing these formats repeatedly
If you master this structure, you can confidently answer almost any WAEC Biology practical specimen question.
