Dicotyledonous seeds contain two cotyledons enclosed within a seed pod, fruit, berry, or other seed structure. Notice in the image how the leaves are broad and netted, and the cross-section features two cotyledons.
These plants have unique characteristics, separating them from monocotyledonous plants as they mature into adulthood, featuring broad, reticulated leaves, meaning the veins will look net-like across the length of the leaf. If the plant flowers, the petals will typically be – but not always – arranged in multiples of fours and fives.
Dicots contain roots which develop from the radicle, which is the first organ to develop inside the seed, becoming the main root structure in a taproot or bulb which collects nutrients and water underground.
Common dicotyledonous plants include oaks, maples, sunflowers, and roses. Agricultural plants of this seed type include radishes, mango, papaya, cocoa, and guava.
