Question

Which of the following statements is not related to Dolichos?
(a) The fruit wall dehisces dorsoventrally into two halves liberating the seeds
(b) Stem is weak and climbs over the support with the help of tendrils
(c) Out of ten stamens in a flower, the filaments of nine stamens are fused to form one bundle and the tenth one remains free as a second bundle
(d) Monocarpellary gynoecium, unilocular ovary, non-endospermic seeds, marginal placentation

Answer 1

Hint: Dolichos is a member of the legumes group. Dolichos is a genus of the family of flowering plants, the Fabaceae, and the Faboideae subfamily. These are herbs and shrubs growing upright, either with stems ascending or prostrate on the ground spreading. Dolichos's fruit wall is one that has two surfaces that differ in appearance and structure from each other. There is one locule in the ovary.

Complete step by step answer:
Dolichos is called legumes as their fruits develop from the monocarpellary superior ovary. They have unilocular ovary and several ovules are arranged with marginal placentation. Mature fruits dehisce by separating them into two sutures, one on each side.
The leaves of this plant are divided into three leaflets, have single blades, or are pinnate. Sometimes after blooming, the plants grow their leaves. The flowers are solitary or numerous in recipes. The flowers are white or purple, or even yellow and they have diadelphous androecium.
Dolichos is a perennial, semi-erect, bushy herb, grown as an annual. They have innate trifoliate leaflets. Flowers are carried on a straight upright stem, sometimes a high foot on which they open successively. The oblong, flat, and thick, firm-walled, and fibrous pods contain 4-6 seeds with a long axis at the right angle to the suture. Near to rounded white, brown, or black seeds. The plant gives off a characteristic odor.
So, the correct answer is, ‘(b) Stem is weak and climbs over the support with the help of tendrils’.

Note: Dolichos is circulating in Africa and Asia. They have woody rhizomes. The general type of the plant, annual stems that sprout from a large perennial rootstock, is believed to be adapted to habitat vulnerable to seasonal wildfire. Some of the species grow to 30 feet in height. Dolichos on average are between 5 and 10 feet tall. Around 60 species of Dolichos exist.
