Question

'Rat-ki-Rani' and tomato belongs to family
A. Mimosoideae
B. Oleaceae
C. Solanaceae
D. Malvaceae

Answer 1

Hint: It is also known as the nightshade family. Its members are recognized by flowers with five petals, sepals, and stamens and typically bear alternate leaves. Many species contain toxic alkaloids.

Complete answer:
To solve this question, at first, we have to know the biological classification of 'Rat-ki-Rani' and tomato. Family is one of the eight major hierarchical taxonomic ranks in Linnaean taxonomy; it is classified between order and genus. Rat-ki-Rani' and tomato belong to the family solanaceae. Solanaceae members are recognized by flowers which have five numbers of petals, sepals, and stamens and commonly bear alternate leaves. Many species contain poisonous alkaloids.
Now lets us find the solution from given options -
A) In the family of mimosoideae plants Leaves are usually twice pinnately compound. Flowers are actinomorphic, petals valvate, distinctly fused; number of stamens is 10 or many and commonly showier than the perianth. Pollen is released as monads, tetrads, or polyads. So, 'Rat-ki-Rani' and tomatoes do not belong to this family.
B) In the family of oleaceae plants dicotyledons account for 600 species of trees, shrubs and sometimes woody climbers. The flowers of most species have four sepals and four petals. Most species have flowers with two stamens (male organs) and one pistil (female organ). So, 'Rat-ki-Rani' and tomatoes do not belong to this family.
C) Rat-ki-Rani' and tomato belong to Solanaceae family. The family levels from annual and perennial herbs to vines, lianas, epiphytes,shrubs, and trees, and contains some of major agricultural crops, medicinal plants, spices, weeds, and decorative plants. Solanaceae individuals are recognised via way of means of flower with 5 petals, sepals, and stamens and usually bear alternate leaves. Many species contain poisonous alkaloids.
D) In the family of malvaceae the plant is generally herbs, shrubs, and a few trees (Gossypium arboreum) with a mucilaginous sap in all elements. Usually young portions of the flowers are included with stellate hairs. So, 'Rat-ki-Rani' and tomatoes do not belong to this family.

Thus, the correct solution is option C. i.e. Malvaceae.

Note: This family is an economically necessary family of flowering flowers. The gynoecium has two carpels, ovary is superior, bilocular, placentation is axile, placentae are swollen, most of ovules in each loculus and ovary obliquely placed.
