The International Code of Botanical Nomenclature $(ICBN)$ has provided a code for the classification of plants. Provide the hierarchy of units of classification that botanists follow while classifying plants and mention the different 'suffixes' used for these units.

(N/A) As per the $ICBN$,the hierarchy of taxonomic categories for plants and their respective suffixes are as follows:

Hierarchy	Suffix
Division	-phyta
Class	-opsida (or -ae)
Order	-ales
Family	-aceae

Note: For Genus and Species,there are no specific suffixes as they form the binomial name. The Genus is the first part of the scientific name (capitalized),and the Species is the second part (specific epithet,lowercase). Both are italicized when printed.
