In a pea flower, five petals are arranged in a specialized manner with one posterior, two lateral and two anterior. These are named as and respectively.
1 Keel, Standard and Carina
2 Standard, Wings and Keel
3 Keel, Wings and Standard
4 Vexillum, Keel and Standard
Explanation:
B Aestivation is the arrangement of either the sepals or petals in a flower bud with relation to one another. - Vexillary is the typical aestivation of the papillionaceae corolla. The posterior vexillum (standard) overlaps the two alae (wing) which again overlap the paired anterior carina (keel). - In this aestivation, the petal i.e. standard overlaps the two smaller lateral petals that are wings which in turn overlap. The two smallest anterior petals are keel.

In Calotropis, aestivation is :
1 Imbricate
2 Twisted
3 Valvate
4 Vexillary
Explanation:
C Arrangement of sepals or petals in floral buds called aestivation. - In velvet floral leaves in a whorl may just touch one another at the margins without overlapping. Ex Calotropis (Asclepiadaceae). - When overlapping is regular in one direction so that one margin overlaps the next member on one side while the other margin is overlapped by that one before. Ex-Cotton, (Malvaceae family) - Imbricate aestivation, the margins of the flower overlap but not in a specific way. Ex- Cassia (Caesalpinaceae). - In vexillary aestivation is a distinctive arrangement in which one gaint petal covers the other smaller petals. Ex- pea (Leguminaceae).

(A) Valvate aestivation:- In this sepals or petals or tepals just touch one another without any overlapping e.g.:- Calotropis procera. (B) Twisted aestivation:- Here, one margin of each petal overlap the margin of an adjacent petal and the other margin being overlapped by margin of another adjacent petal. e.g.:- Cotton, China Rose. (C) Imbricate aestivation:- If the margin of sepals or petals overlap one another but not in any particular direction as in Cassia and Gulmohar, the aestivation is called imbricate. (D) Vexillary aestivation:- It is the characteristics aestivation of corolla of pea when posterior petal is outermost. e.g.:- Bean.

Which one of the following plants shows vexillary aestivation and diadelphous stamens?
1 Solanum nigrum
2 Colchicum autumnale
3 Pisum sativum
4 Allium сера
Explanation:
C In family Fabaceae, pea (Pisum sativum) plant has bilateral symmetry, vexillary aestivation, diadelphous stamens, marginal placentation. - Vexillary or descending imbricate aestivation is the arrangement of corolla in which the anterior petal is innermost and the posterior petal is outermost and largest. Diadelphous - When the filaments are united in two bundles but the anther remain free Marginal placentation is found in unilocular ovary the placenta forms a ridge along the ventral suture of the ovary and the ovules are borne in this ridge.

Verticillaster inflorescence is the characterstic feature of family :
1 Euphorbiaceae
2 Moraceae
3 Musaceae
4 Lamiaceae
Explanation:
D Verticillaster inflorescence is an inflorescence in which the flowers are arranged in a seeming whorl, consisting infact of a pair of opposite axillary, usually sessile cymes as in many mints. In this type of inflorescence, the leaves are arranged in an opposite manner on the stem. It is common among the lamiaceae family. Ex- Salvia and Ocimum. - The euphorbiaceae are distinctive in having unisexual flowers with a superior, usually 3 -carpellate ovary with 1 ovule per carpel, apical axile placentation. - Moraceae have milky or sometimes watery latex. Leaves are mostly alternate, simple, entire and pinnately veined. - Musaceae is the family of monocot perennial herbs and widely distributed in tropical region. It is also called as the banana family, flowers are unisexual or bisexual.
