Question

ICBN stands for
(a)International Classification of Biological Nomenclature
(b)International Class of Biological Nomenclature
(c)International Code of Botanical Nomenclature
(d)International Classification of Biological Naming

Answer 1

Hint: It intends that each taxonomic group of plants has only one correct name that is accepted worldwide. It sets the formal starting date of plant nomenclature on 1 May 1753 in the publication of Species Plantarum by Linnaeus.

Complete answer:
ICBN stands for the International Code of Botanical Nomenclature. A botanical name is fixed to a taxon (groups such as species, family, class) from which the plant belongs. The ICBN can only be changed by the ‘International Botanical Congress (IBC)’ with the help of ‘International Association for Plant Taxonomy.’

Additional Information: -Botanical nomenclature is independent of the zoological and bacteriological nomenclature, which are governed by their codes.
-For the naming of cultivated plants, there is a separate code, ‘the International Code of Nomenclature for Cultivated Plants.’ This gives the supplementary rules and recommendations.
-Botany is also known as plant science, plant biology, or phytology, is the science of plant life and a branch of biology.
-International Code of Botanical Nomenclature (ICBN) is now known as ‘The International Code of Nomenclature for algae, fungi, and plants (ICN).’ The name was changed at the International Botanical Congress in Melbourne in July 2011.
So, the correct answer is, ‘International Code of Botanical Nomenclature.’

Note: The ICBN applies not only to plants, as they are now defined, but also to other organisms traditionally studied by the botanists. This includes the blue-green algae (Cyanobacteria); fungi, including chytrids, oomycetes, and slime molds; photosynthetic protists, and taxonomically related non-photosynthetic groups. There are special provisions in the ICBN for some of these groups, as there are for the fossils.
