Dikotyledona

Dikotyledona, commonly known as dicots, represent a major group of flowering plants. The name "dicotyledona" refers to the presence of two cotyledons, which are embryonic leaves, within the seed. These cotyledons often provide nourishment to the developing seedling. Other distinguishing features of dicots include net-like or reticulate venation in their leaves, and their flowers typically have petals in multiples of four or five. The vascular bundles in the stem of a dicot are arranged in a ring, which allows for secondary growth, leading to the development of wood and bark in many species. This contrasts with monocots, which have a single cotyledon, parallel leaf venation, and scattered vascular bundles. Examples of dicots are abundant and include many familiar plants such as roses, sunflowers, oaks, beans, and tomatoes. This diverse group encompasses a vast array of plant life, from herbaceous annuals to large woody trees, playing crucial roles in ecosystems and human life. The classification of flowering plants has undergone revisions, and the term "eudicots" is now often used for the largest and most diverse clade within the dicotyledons, encompassing the majority of what were traditionally considered dicots.
