Question

Which of the following is phylogenetically most advanced of the dicotyledonous families?
A. Acanthaceae
B. Scrophulariaceae
C. Compositae
D. Umbelliferae

Answer 1

Hint:
Before we proceed to the solution, it is important to know about Compositae.
The Compositae (Asteraceae) family of plants is the largest in the plant kingdom, with 950 genera and 20.000 species. These primary herb plants have latex/oil ducts in their stems, making them the most advanced dicots.
The aster, daisy, or composite family belongs to the flowering plant phylum Asterales and is known by the common name Compositae. Asteraceae is one of the largest plant families in the world, with more than 1,620 genera and 23,600 species of herbs, shrubs, and trees.

Complete step by step answer:
The Compositae (Asteraceae) family of plants is the largest in the plant kingdom, with 950 genera and 20,000 species. These primary herb plants have latex/oil ducts in their stems and are the most highly developed dicots.
The Asteraceae family (Compositae) is recognized as the most developed and highly evolved, and it is thought to hold the highest place in the plant kingdom. Similar to how the structure of an individual flower in certain other plant families helps to draw pollinators, the cluster's overall look also serves this purpose. The earlier family name, Compositae, refers to the fact that what appears to be a single flower is actually a composite of tiny blossoms.
Therefore, phylogenetically the most advanced of the dicotyledonous families is Compositae.

Option ‘C’ is correct

Note:
The characteristics of Compositae are Herbs, shrubs, or trees that comprise this list. They are mainly semi-aquatic, xerophytic, and hydrophytic. As tubers, taproots change. Erect, hairy, woody or prostrate stems can all occur. Latex may occasionally be present. Radical, petiolate, exstipulate, or other leaf types. Flowers are tubular or ligulate in shape, bisexual or unisexual, typically dithecous, filament-free, and have joined anthers. Lacking is the androecium. You can either have a gynoecium or not. It has endosperm in its seed. A cypsela is a fruit that results.
