What region of the grass plant must remain intact for new shoots and roots to grow?

What region of the grass plant must remain intact for new shoots and roots to grow?

• A. Crown
• B. Node
• C. Rhizome
• D. Apex

Answer: (A)

In grasses, the growth point for producing new shoots (tillers) and roots is located in the crown. The crown contains the apical meristem and buds that continuously generate above- and below-ground growth. If the crown is damaged or removed, these meristematic tissues are lost, and the plant cannot produce new shoots or roots, so regrowth largely stops. The other structures aren’t the primary site for initiating new growth in this context. The apex is the tip where growth occurs in a single shoot or root, not the centralized region that supplies multiple new shoots and root primordia. A rhizome is an underground stem that can spread and produce new plants, but it isn’t the main growth center for a single plant’s regrowth after damage at the crown. A node is simply a point on the stem where leaves or buds attach, not the central growth region responsible for new shoot and root formation.
