Answer 1

Answer:

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.

Answer 2

Answer:

1 is incorrect

because the plant can be collected at the stage after the flowering also it is need not be followed because if we want the only flower we should take if we don't need it it is need not to be taken.

herbarium sheets are the sheets which contain this plants .

First we have to collect the plant and we should put it in the news papers or papers so the all plant parts are evenly pressed.so that much it's watery content will leave so that easily the fungus can't effect that.and after a week we should remove the specimen from the papers and we should paste it in the sheets.

then the information regarding that such as the floral information, family,etc should be written down of it.

if it helps you thank me .
