Reproduction in flowering plants: WAEC Biology Past Questions and Answers

What the WAEC syllabus covers in Reproduction in flowering plants

Our summary: Flower structure, pollination, fertilization, fruits and how fruits and seeds are dispersed.

• Arrangements of floral parts of a named insect-pollinated flower and a named wind-pollinated flower
• Structure and function of the male and female parts of a flower
• Pollination in plants: types of pollination (Named examples should be used to illustrate the types of pollination.)
• Features of cross-pollinated and self-pollinated flowers
• Agents of pollination (The features of the flower should be related to the agents of pollination.)
• Kinds of placentation: axile, marginal and parietal
• Process of development of zygote in flowering plants: fertilization (Pollen grains germinated in sucrose solution should be observed, prepared slides or charts showing various stages of embryo development in flowering plants should be observed and drawn.)
• Types of fruits (classification) (Fruits should be classified into dry and fleshy fruits.)
• Structure of fruits (The internal structure of a leguminous fruit, orange, maize and tomato should be examined and drawn.)
• Dispersal of fruits and seeds: agents of dispersal (The following fruits should be studied as examples to show the features that aid their respective methods of dispersal. Sunflower (achene), Combretum, cotton, Crotalaria/bean, Desmodium, Bidens sp., Tridax sp. and Coconut. Distinguishing differences between a fruit and a seed should be mentioned.)
