Column A	Column B
A) Polyadelphous	(i) Polypetalous
B) Pollen grains	(ii) Calyx, Corolla
C) Free petals	(iii) Nectar
D) Non-essential	(iv) Bombax
E) Sweat fragrant fluid	(v) Pollen sac

(a) A - (v), B - (iv), C - (iii), D - (ii), E - (i)
(b) A - (i), B - (ii), C - (iii), D - (iv), E - (v)
(c) A - (iv), B - (v), C - (i), D - (ii), E - (iii)
(d) A - (ii), B - (v), C - (i), D - (iv), E - (iii)

Answer 1

In the given table both the columns are provided with parts or type of flowers and also substances related to the flowers and name of plants to which the specific flower belongs too.

Complete answer:
In the provided column A and column B Polyadelphous is associated with Bombax, pollen grains are associated with pollen sac, free petals are associated with polypetalous, non-essential is associated with calyx, corolla and sweat fragrant fluid is associated with nectar.
A) The term Polyadelphous is associated with stamen. The Polyadelphous stamen is the stamen whose filaments are fused or united by the anthers into two or more or several groups or bundles. The androecium of flowers having polyadelphous stamen,shows varying degrees of fusion between the filaments and the anthers. Polyadelphous stamens are found in bombax trees belonging to the Malvaceae family. It grows in tropical countries and is cultivated in the West Indies and Brazil to obtain tree cotton.
B) Pollen grains are produced inside the pollen sac. They develop from microspore mother cells situated at the inner walls of the pollen sac by the process of meiosis. Pollen sacs are usually bi-lobed microsporangia.
C) Free petals are a condition in flowers when the petals of the corolla are not fused they are free, this condition is called polypetalous. The polypetalous flowers are flowers having distinct petals.
D) Non-essential is related to the Calyx and Corolla because calyx or sepals and corolla or petals are not directly involved in the sexual reproduction of flowers. They are very bright and colorful thus indirectly involved in the process by attracting the pollinators. E) Sweat fragrant fluids are produced in the nectaries or nectarines gland by the plants. These fluids are called nectar. Nectar is the sugar source for honey so it is considered an economically important substance.

So, the correct answer is, 'A - (iv), B - (v), C - (i), D - (ii), E - (iii)'.

Note:
-Polyadelphous stamens are found in bombax trees belonging to the Malvaceae family.
-Pollen grains are produced inside the pollen sac.
-The polypetalous flowers are flowers having distinct petals or free petals.
-Calyx and corolla are non-essential parts of flowers because they are not directly involved in sexual reproduction.
-Nectar is the sweat fragrant fluid found in the flowers.
