Whorl

Whorl is a term used in various fields of study, including biology, botany, and forensics. It refers to a pattern that spirals around a central point or axis. In biology, it is often used to describe the arrangement of leaves, petals, or other structures in plants. In forensics, it is used to describe a type of fingerprint pattern.

Biology

In biology, a whorl refers to a circular arrangement of parts around a central axis. This can be seen in the structure of certain plants and animals. For example, the petals of a flower may be arranged in a whorl around the central stamen.

Botany

In botany, a whorl is a specific arrangement of leaves, petals, sepals, or stamens around a stem. This is also known as a verticil. Plants with this type of arrangement are said to be whorled. Examples of plants with whorled leaves include milkweed and bedstraw.

Forensics

In forensics, a whorl is a type of fingerprint pattern. It is characterized by circular ridges that spiral around a central point. There are four types of whorl patterns: plain whorl, central pocket loop whorl, double loop whorl, and accidental whorl. These patterns are used in fingerprint analysis to help identify individuals.
