What term describes a circular cluster of leaves radiating from the stem at ground level?

• A. Rosette
• B. Whorl
• C. Phyllotaxy
• D. Tuft

Answer: (A)

The concept here is a basal leaf pattern where leaves radiate outward in a circular cluster from a common point at ground level. That arrangement is called a rosette. In a rosette, leaves spread from a central crown and form a circular outline right at or near the soil, as seen in plants like dandelions or lettuces.

A whorl describes leaves arranged in a ring around the stem at a single node along the stem, typically higher up, not at ground level. Phyllotaxy is about the overall pattern of leaf arrangement along the stem (alternate, opposite, whorled), not specifically a ground-level circular cluster. A tuft refers to a small bunch of leaves or hair, but it doesn’t specifically convey radiating circular arrangement from the stem at soil level.

So, the circular cluster of leaves radiating from the stem at ground level is a rosette.
