What pattern is defined as "whorl"?

• A. Pattern of leaves arranged randomly
• B. Circulating pattern of twigs around a stem
• C. Line of trees in a row
• D. Setting of leaves in an alternating pattern

Answer: (B)

The term "whorl" specifically refers to a pattern where twigs or leaves are arranged in a circular manner around a central stem or axis. This configuration can often be observed in various plant species, where the arrangement allows for optimal exposure to sunlight and efficient growth. The whorled arrangement is distinct from other patterns, as it does not align in a linear fashion or alternate, but rather encircles the stem, creating a visually striking formation. In contrast, the other options describe different types of arrangements. For instance, random arrangements do not exhibit any specific pattern, while a line of trees in a row represents a linear organization. An alternating pattern of leaves typically involves a staggered layout on either side of a stem rather than the uniform circular pattern characteristic of a whorl. Understanding these definitions helps clarify why the whorl is recognized distinctly in botany.
