Brief Explanation of the Biology Specimen for WAEC 2024
Specimen A: Mature fresh eggs of catfish
These are fully developed and viable eggs from a catfish, demonstrating reproductive characteristics and allowing students to study the developmental stages of fish embryos.
Specimen B: Fresh egg of domestic fowl (raw, with shell intact)
This specimen provides an opportunity to examine the structure of a bird's egg, including the shell, membranes, and yolk, which is crucial for understanding avian reproduction.
Specimen C: Picture/model/chart of uterus containing a foetus
This visual representation aids in studying the anatomy of the uterus with a foetus. It allows students to identify and understand the structures involved in the development of a mammalian embryo.
Specimen D: Longitudinal section of ovary of pride of Barbados flower
This section of the flower's ovary provides insight into plant reproduction, showcasing the arrangement of ovules and other reproductive structures within the ovary.
Specimen E: Leaf of pride of Barbados flower
The leaf specimen allows for the examination of leaf structure, venation patterns, and adaptations, providing insights into the plant's physiology and ecological role.
Specimen F: Panicum plant/Guinea grass (whole plant)
Studying the entire plant enables students to observe its morphology, including root structure, stem characteristics, and reproductive features, contributing to a comprehensive understanding of grass plants.
Specimen G: Cocoyam plant/Caladium plant (whole plant)
This specimen allows for the observation of the entire cocoyam or caladium plant, facilitating the study of root tubers, leaves, and overall plant structure.
Specimen H: Corm of Cocoyam
The corm, an underground storage organ, is essential for studying plant adaptations. It provides nutrients and serves as a point of interest for understanding the plant's life cycle.
Specimen J: Dry humus in a beaker
Dry humus represents decomposed organic matter in soil. Studying this specimen aids in understanding soil composition, nutrient cycling, and the role of humus in supporting plant growth.
Specimen K: Moist humus in a beaker
Moist humus, being organic matter in a hydrated state, allows students to investigate the influence of moisture on soil characteristics and its significance in supporting plant life.
Specimen L: Ripe orange fruit (whole)
This fruit specimen provides insights into the structure of a fleshy fruit, seed dispersal mechanisms, and the nutritional content of the fruit, contributing to a broader understanding of plant reproduction.
Specimen M: Longitudinal section of coconut fruit
This section enables the examination of the internal structures of a coconut fruit, including the endosperm and embryo, offering insights into seed development and coconut reproduction.
Specimen N: Longitudinal section of fresh chili pepper fruit
Studying the longitudinal section of a chili pepper fruit allows for the observation of seed distribution, placenta arrangement, and fruit anatomy, enhancing understanding of pepper plant reproduction.
