plants

My son has to do a project on monocots
and dicots, which I know are plants but he has to have 4 examples of each and place them on a poster board tell about them, etc. and to do a rubric about this project. I am having trouble finding what they are and the examples since he left his science book at school.


Monocots, more properly monocotyledons, one of two classes of flowering plants (see Angiosperm). They are mostly herbaceous and include such familiar plants as iris, lily, orchid, grass, and palm. Several floral and vegetative features distinguish them from dicots, the other angiosperm class. These features include flower parts in threes; one cotyledon (seed leaf); leaf veins that are usually parallel; vascular tissue in scattered bundles in the stem; and no true secondary growth.

Monocots are thought to have evolved from some early aquatic group of dicots through reduction of various flower and vegetative parts. Among living monocot groups, one order (see Water Plantain) contains the most primitive monocots. About 50,000 species of monocots are known—about one-third the number of dicot species.

Scientific classification: Monocots make up the class Liliopsida of the phylum Magnoliophyta. The most primitive living monocots belong to the order Alismatales.

Dicots, popular name for dicotyledons, one of the two large groups of flowering plants. A number of floral and vegetative features of dicots distinguish them from the more recently evolved monocotyledons (see Monocots), the other class of flowering plants. In dicots the embryo sprouts two cotyledons, which are seed leaves that usually do not become foliage leaves but serve to provide food for the new seedling. See Seed.

Flower parts of dicots are in fours or fives, and the leaves usually have veins arranged in a reticulate (netlike) pattern. The vascular tissue in the stems is arranged in a ring, and true secondary growth takes place, causing stems and roots to increase in diameter. Tree forms are common. Certain woody dicot groups (see Magnolia) exhibit characteristics such as large flowers with many unfused parts that are thought to be similar to those of early flowering plants. About 170,000 species of dicots are known, including buttercups, maples, roses, and violets.

Scientific classification: Dicots make up the class Magnoliopsida, in the
