Question

Persistent calyx is characteristic of
a. Allium/Liliaceae
b. Hibiscus/Malvaceae
c. Dalbergia/Papionateae
d. Solanum/Solanaceae

Answer 1

Hint: The peripheral whorl of the bloom that establishes sepals is known as calyx. For the most part sepals are green leaf like and they secure the bloom in the bud stage. The calyx might be gamosepalous (sepals stay joined together) and polysepalous (when sepals stay free). The bit of the calyx which stays with the natural product gets developed is named as relentless calyx.

Complete answer:
• In the Allium/Liliaceae family calyx and corolla get intertwined to frame perianth. They have valvate aestivation. So calyx isn't relentless in this family.
• In malvaceae family calyx are normally five and are isolated. The calyx doesn't stay joined with natural products. In this way, persevering calyx isn't normal for the malvaceae family.
• Dalbergia/papilionatae has a gamosepalous condition yet not a steady calyx. The calyx of this might be equivalent and inconsistent.
• In Solanum/Solanaceae family the calyx has a gamosepalous condition. They have tenacious calyxes and show valvate aestivation. Along these lines, this alternative is right.

Hence, the correct answer is option (D).

Additional information:
Called the nightshade family or the potato family, Solanaceae has in excess of 90 genera and almost 3,000 species conveyed all through the world. Its individuals are portrayed by blossoms with five petals, sepals, and stamens and normally bear substitute leaves. Numerous species contain poisonous alkaloids.
Alkaloid is a class of normally happening natural nitrogen-containing bases. Alkaloids have different and significant physiological consequences for people and different creatures. Notable alkaloids incorporate morphine, strychnine, quinine, ephedrine, and nicotine.

Note: When sepal exists till the fruit formation and also present even after maturation of fruit. This condition is called persistent calyx. Principally the calyx and corolla shed after the development of organic product or vegetable yet here and there it stays with the natural product as on account of solanaceae and in organic products like strawberry.
