Answer 1

Hint: Hibiscus belongs to an order that houses families like those of cotton plants. The characteristic feature of this order is the presence of mucilage canals in its tissue. The species of Hibiscus is commonly known as China rose.

Complete answer:
The hierarchy of a plant includes its taxonomic representation wherein it is stepwise classified into various taxonomic categories based on similarities and dissimilarities.
Hibiscus is an annual and perennial flowering plant. It is particularly found in warm temperate and subtropical regions. It is a dicotyledonous plant under the order of Malvales and family Malvaceae. Its famous species include Hibiscus rosa-sinensis and Hibiscus syriacus.
-Hibiscus is a dicotyledon because its seeds contain two cotyledons and are non-endospermic.
-The order Malvales is famous for its palmate venation in leaves where three principal veins have the same origin at the base of the leaf blade. Tissue bears mucilage canals which is evident in a slimy layer appearance. Star-shaped or stellate hairs grow on their vegetative parts and also on their stipules which are leaf-like structures at the base of the leaf stalk.
-The floral characters of the Malvaceae family include actinomorphic flowers, bracteate,5 calyces, 5 or polypetalous, monadelphous androecium and hypogynous flower with multicarpellary ovary.
-Sapindales is an order for plants like that of the Citrus family. These are generally woody plants with trees, woody climbers, and large shrubs.
-Rosales is an order of flowering plants including families such as Rosacea and Urticaceae.

So, the correct answer is ‘Malvales, rosa-sinensis.’

Note:
-About 85 genera and 1500 species are included in Malvaceae. Some notable members of this family include Abelmoschus esculentus (ladyfinger), Gossypium (cotton).
-Pollination usually occurs with the help of insects i.e entomophily. Self-pollination is prevented by protandry where the male sex organ develops before the maturation of the female organ.
