Question

Select the correct statement
A. Biological names are generally in Greek and written in Italics
B. Family comprises a group of related species which has more characters in common
C. Triticum aestivum comes under the order Sapindales
D. An order includes related classes
E. Family like Convolvulaceae and Solanaceae are included in the order polemoniales mainly based on floral characters

Answer 1

On the basis of whether plants have a well-differentiated body and the presence or lack of specialized tissues for transport, the capacity to carry seeds Kingdom Plantae (Plant Kingdom) can be divided into different divisions such as different families, orders, species and classes etc, They have universal biological names.

Complete answer:
A. Biological names are usually in Latin and written in italics, as per the laws of nomenclature. For example Biological names given for Sunflower is Helianthus annuus and that for Housefly is Musca domestica. Thus the statement 'Biological names are generally in Greek and written in Italics' is incorrect.

B. Families form a group of linked genera with fewer similarities and not of those having more common characters. Walnuts (genus Juglans) and hickories (genus Carya), for example, are all members of the walnut family (the Juglandaceae). Thus the given statement is incorrect.

C.Triticum aestivum is the cultivated species of common wheat, also known as bread wheat. It belongs to the family of Poaceae and order Poales. Sapindales is a dicotyledonous flowering plant order that consists of 9 families, 460 genera, and 5,700 species of shrubs, woody vines, and trees. It contains the Citrus genus as well as other fruit-producing plants.

D. A class consists of one or more linked orders. The Dicotyledoneae class of flowering plants, for example, includes all dicots grouped into multiple orders, such as Rosales, Passifloraceae, Asterales, Sapindales, etc. Similarly, all mammals are in the mammalian class of animals.

E. Plant families including Convolvulaceae and Solanaceae are primarily based on the floral/sexual characters in the order Polemoniales. They have flowers adnate to the corolla lobes with stamens and a single superior compound ovary.

Thus front the above discussion it is clear that the correct answer is option E that is 'Family like Convolvulaceae and Solanaceae are included in the order polemoniales mainly based on floral characters.'

Note: The system of binomial nomenclature which was introduced by Carl Linnaeus is the biological method of naming the organisms of which the name is composed of two words, where the first word indicates the genus and the second term indicates the species of the organism. The international body which deals with biological nomenclature for plants is the International Code of Botanical Nomenclature (ICBN).
