Reproductive organs include flowers, fruits and seeds. Examples of vegetables will be used to illustrate the different organs and their parts. Differences between Monocot and Dicots Cotyledon is a food storage area in the embryo of a plant. Monocotyledonous plants are a class of flowering plants that may be recognized because they have only one cotyledon. The other characteristics of monocots include parallel veins in leaves, vascular bundles scattered through a monocots stem's cross section, tend to have fibrous roots, and their monocot flower parts are in 3 or multiple of 3's.
Dicotyledonous plants are a class of plants that have two cotyledons.
The other characteristics of dicots include net venation in leaves, vascular bundles arranged in a ring inside the perimeter of a stem, dicot flower parts either are in 4's or 5's or their multiples. On plants that live more than one year the twigs lose their leaves in the autumn forming a winter twig . Many of the external features that are characteristics of a species of plant can be learned from looking at the winter twig. Leaf arrangements can be determined by looking at the leaf scars which denotes where leaves where attached to the stem at a node. Inside of leaf scars there are often bundle scars where veins break when the leaves break off the stem.
