A sunflower seed is a dicot that contains the characteristic double cotyledon. The cotyledon, also known as a seed leaf, holds food reserves for the developing seed.Know More
Monocots are marked by a single cotyledon that is contained inside their seed coat. When a monocot begins to grow, the seed leaf produces a single leaf on the new plant. A monocot leaf is long, narrow and contains veins that run up and down the length of the leaf. Its roots are unbranched and fairly fragile.
Dicots produce two leaves when they first germinate. The leaves of a dicot vary in shape and size, with the veins extending out from the center to form. Roots of a dicot are tough and branched.Learn more about Outdoor Plants & Flowers
According to the University of California Museum of Paleontology, the major morphological differences between monocot and dicot flowers include the number of cotyledons, pollen structure, number of flower parts, leaf veins, stem vascular arrangement, root development and secondary growth. The actual basis for differentiating the two classes of angiosperms is the number of cotyledons in the embryo.Full Answer >
Dicot stems have a circular arrangement of vascular tissues, whereas the stems of monocots have vascular-tissue bundles scattered throughout. In monocots the vascular bundles also tend to be toward the outside of the stem. Dicot vascular tissue forms a cylinder near the center of the stem.Full Answer >
The sunflower adapts through its heliotropic head, bristles on the stem of the sunflower, leaves that are broad and oppositely positioned and overall versatility. Sunflowers can function in a variety of climates and soil types, as well as drought. Its heliotropic head moves to follow the sun, from east to west and back east again at the end of the day.Full Answer >
