Why is the aster flower a diot?

The aster flower is classified as a dicot (or dicotyledon) because it exhibits key characteristics typical of this group, such as having two cotyledons in its seeds, broad leaves with a net-like venation pattern, and flower parts arranged in multiples of four or five. Additionally, its vascular tissue is arranged in a ring within the stem, which is another distinguishing feature of dicots. These traits align with the broader classification of dicot plants within the angiOSperms.
