Dicots may be herbaceous (for example, a tomato plant) or woody (for example, a hickory tree). Their leaves vary in shape but usually are broader than monocot leaves, with netted veins (branched veins resembling a net). Flower parts usually occur in fours or fives or multiples thereof. Two cotyledons are present in dicot seeds, and endosperm is usually absent in the mature seed, having been absorbed by the two cotyledons. The vascular bundles in the stem cross section of dicots is arranged in a circle, or ring. The root...

The vascular bundles in the stem cross section of dicots is arranged in a circle, or ring. The roots are a taproot system.
