Practice question

When authentic floral diagram drawn following developmental observations, organ initiation proceeds centripetally meaning progression from outside toward inside following acropetal order on determinate floral apex where growth terminates with carpel primordia. Sequence begins with calyx as first initiated sepals forming outermost whorl, then corolla petals, then androecium stamens, finally gynoecium carpels occupying innermost central summit. This centripetal arrangement reflects genetic program governed by ABCDE MADS-box model organ identity genes with overlapping expression domains. Alternative orders would misrepresent ontogenetic pattern and misinterpret evolutionary relationships.
