Specimens are samples or examples of a particular type of material, organism, or object that are collected for study or analysis. They can be used in various fields, such as biology, geology, and medicine, to help scientists understand characteristics, behaviors, or properties. For instance, a plant specimen might be collected to study its growth patterns, while a blood specimen can be analyzed to diagnose health conditions. In laboratories, specimens are often preserved and labeled to ensure accurate identification and analysis. They can include tissue samples, mineral samples, or even insect specimens. Proper handling and storage of specimens are crucial for maintaining their integrity and usefulness in research.
