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 researchers understand characteristics, behaviors, or properties. For instance, a biological specimen might include a tissue sample from a plant or animal. In laboratories, specimens are often preserved and cataloged for future reference. They can also be used in educational settings to teach students about different species or materials. Collecting specimens is essential for scientific research, as it allows for detailed examination and comparison across different contexts.
