Answer 2

Answer:

ascular plants contain two main types of conduction tissue, the xylem and phloem. These two tissues extend from the leaves to the roots, and are vital conduits for water and nutrient transport. In a sense, they are to plants what veins and arteries are to animals. The structure of xylem and phloem tissue depends on whether the plant is a flowering plant (including dicots and monocots) or a gymnosperm (polycots). The terms dicot, monocot and polycot are summarized in the following table.

Class Monocotyledoneae: Monocots

Flower parts in 3's or multiple of 3's; one cotyledon inside seed; parallel leaf venation; includes Lilium, Amaryllis, Iris, Agave, Yucca, orchids, duckweeds, annual grasses, bamboos and palms.

Class Dicotyledoneae: Dicots

Flower parts in 4's or 5's; 2 cotyledons inside seed; branched or net leaf venation; contains the most species of flowering herbs, shrubs and trees; includes roses (Rosa), buttercups (Ranunculus), clover (Trifolium), maple (Acer), basswood (Tilia), oak (Quercus), willow (Salix), kapok (Ceiba) and many more species.

Gymnosperms: Plants With Naked Seeds

Gymnosperms include pines (Pinus), spruce (Picea), fir (Abies), hemlock (Tsuga) and false hemlock (Pseudotsuga). Some of the coniferous genera (division Coniferophyta) are the most important timber trees in the world. Since these species have several cotyledons inside their seeds, they are conveniently referred to as polycots.
