As we go from species to kingdom in a taxonomic hierarchy, the number of common characteristics
(a) As we go higher from species to kingdom, the number of common characteristics goes on decreasing. Lower the taxa, more are the characteristics that the members within the taxon share. Higher the category, greater is the difficulty of determining the relationship to other taxa at the same level.
Which of the following ‘suffixes’ used for units of classification in plants indicates a taxonomic category of ‘family’.
(c)
(a) -Ales -> Order (plant)
(b) -Onae -> Class (plant)
(c) -Aceae -> Family (plant)
(d) -Ae -> Phylum (plant)
The term ‘systematics’ refers to:
(c) Human beings were, since long, not only interested in knowing more about different kinds of organisms and their diversities, but also the relationships among them. This branch of study was referred to as systematics. Systematics takes into account evolutionary relationships between organisms.
Genus represents
(c) Genus comprises a group of related species which has more characters in common in comparison to species of other genera.
The taxonomic unit ‘Phylum’ in the classification of animals is equivalent to which hierarchical level in classification of plants
(c) Classes comprising animals like fishes, amphibians, reptiles, birds along with mammals constitute the next higher category called Phylum. All these classes are included in the phylum chordata. In case of plants, classes with a few similar characters are assigned to a higher category called Division.

(c) Flora contains the actual account of habitat and distribution of plants of a given area. These provide the index to the plant species found in a particular area. Manuals are useful in providing information for identification of names of species found in an area. Monographs contain information on any one taxon, i.e. any one genus or family at a particular time. They also help in correct identification.
All living organisms are linked to one another because
(b) All living organisms – present, past and future are linked to one another by the sharing of the common genetic material, but to varying degrees.
