Grass Plant Structure and Growth - Key Parts of a Grass Plant

In order to better appreciate how grass plants grow, it is important to know something about the various plant tissues and organs involved in that growth. The major grass parts are shown in Figures 3.1a and 3.1b.

The leaf is composed of two parts: the leaf blade and the leaf sheath. Looking at the grass plant closely will reveal that the leaf rolls itself around the stem (or shoot) forming the leaf sheath.

The leaves, stems, and roots all originate from the crown of the plant.

The crown is a very tightly compressed stem or growing point that pushes the new leaves upward as they are formed and grow. This is a different growth habit than found in other garden plants such as tomatoes, marigolds, trees, and shrubs. In those instances, the outward growth extends from the tips of the branches or shoots. The location of the grass crown near the base of the plant and usually at, or slightly below the soil line allows us to mow our lawns regularly and yet have continued growth.
