While grasses vary considerably in their growth habits and habitats and may be perennial or annual, they share some things in common. Almost all grasses are herbaceous. The seed contains an embryo with one cotyledon, as opposed to legumes with two monocotyledons. The cotyledon of all grass seedlings remains below the soil upon emergence.
The basic organs of grasses are leaves, stems, and roots (Fig. 1). Specially modified stems and leaves constitute the inflorescence and fruits. Leaves are attached to the stem, one at each node, alternately in two rows on opposite sides of the stem. Leaf blades are typically flat, narrow, and parallel-veined.
