WAEC BIOLOGY PRACTICAL SPECIMEN 2024/2025
HERE IS THE DESCRIPTION OF THE SPECIMENS FOR THE WAEC BIOLOGY PRACTICAL EXAM 2024/2025:
IMPORTANT MATERIALS
To conduct the WAEC Biology Practical Exam 2024/2025 effectively, each candidate will need these essential materials:
1- Spatula
2- Petri dish
3- Fehling’s solutions A and B
4- Iodine solution
5- Hand lens/magnifying lens
6- Scalpel/razor blade/knife
7- Pair of forceps
8- Hand gloves
These materials will help candidates examine various specimens, from fish eggs to plant parts and soil components, during the exam.
DETAILED EXPLANATION OF THE WAEC BIOLOGY PRACTICAL SPECIMEN 2023/2024
Here is a detailed explanation of the WAEC Biology Practical Specimen for 2023/2024:
1. Specimen A:
Mature fresh eggs of catfish: These are fully developed eggs from a catfish. Candidates may need to observe their structure, size, and possibly stages of development.
2. Specimen B:
Fresh egg of domestic fowl (raw, with shell intact): This refers to an uncooked chicken egg with the shell still on. Students might examine its external features, such as the shell texture and color.
3. Specimen C:
Picture/model/chart of uterus containing a fetus: This could be a visual representation or model of the uterus of a mammal, like a human or other animal, showing the presence of a developing fetus. Candidates might be asked to identify different parts of the uterus and the fetus.
4. Specimen D:
Longitudinal section of ovary of pride of Barbados flower: This is a cut section of the ovary from a pride of Barbados flower. Students might study its internal structure, including ovules and other reproductive parts.
5. Specimen E:
Leaf of pride of Barbados flower: This refers to a leaf from the pride of Barbados plant. Candidates may examine its external features, such as shape, margin, venation, and possible adaptations.
6. Specimen F:
Panicum plant/Guinea grass (whole plant): This is the entire plant of Panicum grass, also known as Guinea grass. Students might study its morphology, including stem, leaves, flowers, and roots.
7. Specimen G:
Cocoyam plant/Caladium plant (whole plant): This represents the entire plant of cocoyam, also known as Caladium. Candidates may observe its overall structure, including leaves, stems, and roots.
8. Specimen H:
Corm of cocoyam: This refers to the underground bulb-like structure of the cocoyam plant. Students might examine its external features and internal structure.
9. Specimen J:
Dry humus in a beaker: This is dry organic material from the soil, commonly referred to as humus. Candidates might study its texture, color, and composition.
10. Specimen K:
Moist humus in a beaker: Similar to Specimen J, but this is moist humus. Students may compare its properties to dry humus and observe any differences.
11. Specimen L:
Ripe orange fruit (whole): This is a complete ripe orange fruit. Candidates might examine its external features, such as color, texture, and structure, and possibly its internal anatomy.
12. Specimen M:
Longitudinal section of coconut fruit: This is a cut section of the coconut fruit, showing its internal structure. Students might observe the arrangement of tissues and the presence of endosperm and embryo.
13. Specimen N:
Longitudinal section of fresh chili pepper fruit: This is a cut section of a fresh chili pepper fruit, displaying its internal structure. Candidates might observe the arrangement of seeds, placenta, and pericarp.
These specimens provide a wide range of biological materials for students to observe and study, helping them understand various aspects of plant and animal biology.
Conclusion
In conclusion, candidates should ensure thorough preparation for the practical examination to effectively demonstrate their practical skills and grasp of biological concepts. By familiarizing themselves with the specimens and essential materials provided, candidates can approach the exam confidently and showcase their abilities to the fullest extent.
