Answer 1

The correct option is A Only I

Herbarium sheets serve the purpose for quick referral systems in the study of taxonomy. These sheets contain specimens that are dried and evenly pressed with the help of a plant presser. The herbarium sheet is labelled with details like locality, ecological condition, vegetative and floral characteristics, date of collection, botanical name, family name, collector's name, etc. However, for the preparation of herbarium sheets, it is not necessary for the plant to be in its flowering stage.

So, the correct answer is option A.
