Question

Which of the following is the characteristics of leguminosae?
A Zygomorphic flower
B Raceme inflorescence
C Calyx with imbricate venation
D All of the above

Answer 1

Hint The Fabaceae or Leguminosae family of flowering plants, also known as the legume, pea, or bean family, is a huge and commercially significant flowering plant family. It contains trees, shrubs, and perennial or annual herbaceous plants with fruit and compound, stipulate leaves that are clearly identified.

Complete step by step answer:
Leguminosae is a dicot plant family that is distinguished by the following characteristics
Floral symmetry refers to the ability of a flower, specifically its perianth, to be divided into two or more identical or mirror-image portions. Flowers, on the other hand, rarely have an axis of symmetry since their parts are spirally arranged.
A zygomorphic flower is one that may be divided into two equally spaced mirror parts that are done on the same plane.

A group or cluster of flowers formed on a stem made of a primary branch or a sophisticated arrangement of branches is known as an inflorescence. It is the modified section of the seed plant's shoot where flowers are generated morphologically.
A raceme, also known as a racemoid, is an indeterminate, unbranched form of inflorescence that bears pedicellate flowers along its axis. An axis in botany refers to a shoot, in this case the one bearing the flowers.

In a flower bud, aestivation is the placement of accessory floral organs (sepals or petals) in relation to one another. The kind might be valvate, open, imbricate, or twisted. Imbricate aestivation occurs when the margins of petals or sepals overlap without a defined direction.
There is an uneven overlapping of petals by each other in this type of aestivation. Aside from the imbricate proper, they have ascending imbricate, quincuncial, and descending imbricate subtypes. This aestivation can be seeded on Pisum, Cassia, and other plants.

As a result, the right answer is Option D: "All of the Above."

Note: Due to their extraordinary diversity and abundance, the wide variety of edible vegetables they represent, and the variety of uses they can be put to: in horticulture and agriculture, as a food, for the compounds they contain that have medicinal uses, and for the oil and fats they contain that have a variety of uses, legumes are economically and culturally important plants.
