SET 4
Introduction
This set covers
sexual reproduction in flowering plants. Questions focus on flower structure,
unisexual and bisexual flowers, pollination types, fertilisation, gamete
formation, and the development of seeds and fruits. The set also explains why
sexual reproduction creates more variation than asexual reproduction.
