FAQs on Taxonomical Aids Video Lecture - Biology Class 11 - NEET

1. What are taxonomical aids?
Ans. Taxonomical aids are tools that help in the identification, classification, and naming of organisms. These aids include keys, field guides, monographs, herbarium specimens, museum specimens, and databases.
2. What is the importance of taxonomical aids in biology?
Ans. Taxonomical aids play a crucial role in biology by helping to identify and classify organisms. They also enable scientists to study the relationships between different species, which is essential for understanding the diversity of life on Earth and how it has evolved over time.
3. What is the difference between a key and a field guide?
Ans. A key is a taxonomic aid that uses a series of dichotomous (either/or) questions to identify an unknown organism. A field guide, on the other hand, is a book or other resource that provides illustrations and descriptions of different species to help in their identification.
4. How are herbarium specimens used as taxonomical aids?
Ans. Herbarium specimens are dried and pressed plant specimens that are mounted on paper and stored in herbaria. These specimens serve as a reference for the identification and classification of plants. They can also be used to study the distribution and ecology of different plant species over time.
5. What are some of the challenges in using taxonomical aids?
Ans. One of the main challenges in using taxonomical aids is the difficulty in identifying and classifying organisms that are very similar to one another. Another challenge is the lack of comprehensive resources for certain groups of organisms, which can make identification and classification difficult. Additionally, taxonomical aids can become outdated as new species are discovered, and taxonomic relationships between species are revised.
