1. (c) Herbarium is a place where dried and pressed plant specimen mounted on sheets are kept systematically.
Key is the Identification of various taxa. Museum is an institution where plant and animal specimen are exhibited to public. A collection may include scientific specimen works of arts etc. Catalogue is an alphabetical listing of species.
2. (a) Binomial nomenclature is a formal system of naming species of living things by giving each a name composed of two parts, both of which use Latin grammatical forms, although they can be based on words from other languages.
