Question

Epipetalous stamen, obliquely placed placenta and fruit berry or capsule are diagnostic features of family
A)Cruciferae
B)Solanaceae
C)Malvaceae
D)Labiatae

Answer 1

Hint: Families of flowering plants and family relationships have been determined primarily by morphology for more than 250 years (the structure, shape and number of plant parts). To some extent, the previous morphological classifications were accompanied by molecular research.

Complete answer:
One of the eight most hierarchical taxonomic ranks of Linnaean taxonomy is the family (Latin: familia, plural familiae); it is divided within order and genus. It is possible to split a family into subfamilies, which are intermediate ranks between the family and genus ranks. The official family names are of Latin origin, although informal names are also used: walnut trees and hickory trees, for instance, belong to the Juglandaceae family, but the "walnut family" is generally referred to as that family.

As an economically valuable family of flowering plants, the members of the Solanaceae family consist of some 98 genera and some 2,700 species. Few of the family's characteristics include-stamens-generally 5 and epipetal, regardless of the presence of pseudo septum, the gynoecium is bicarpellary, syncarpous, bilocular or tetralocular. The ovary is superior and positioned obliquely. A berry or capsule is the fruit.

Hence, the correct answer is option (B)

Note: In zoology, Pierre André Latreille presented the family as an intermediate rank between order and genus in his Précis des caractères génériques des insectes, disposés dans un ordre naturel (1796). In some but not all of his "insect" orders, he used families (some of them were not named) (which then included all arthropods).
