Question

Which floral family has \[\left( 9 \right) + 1\] arrangement of anthers in the androecium?
A. Malvaceae
B. Rutaceae
C. Fabaceae
D. Caesalpiniaceae

Answer 1

Hint: The Asteraceae are a very diverse family and include both annual and perennial plants, as well as herbs, shrubs, and trees. The most frequent androecium condition among members of the Fabaceae family is diadelphous, which occurs when nine of the ten stamens are joined by the bottom half of their filaments to create an incomplete tube around the pistil. The tenth stamen towards the back of the flower is unattached.

Complete step-by-step answer:
One of the most notable features of the Asteraceae is their flower heads, which are composed of many tiny flowers called florets. The florets are arranged in a spiral pattern, and each has its own set of stamens (the male reproductive organs) with 9+1 anthers. The central floret in the flower head is usually more prominent and showy than the others and is called the disc floret. The Asteraceae is sometimes referred to as the "daisy family" because of the typical appearance of their flower heads.
The Asteraceae are an essential family of plants for their economic value and ecological role. They are a significant food source for humans and animals, and their flowers provide nectar for pollinators such as bees and butterflies. In addition, the Asteraceae are an essential part of the global ecosystem, and their flowers play a role in seed dispersal. The androecium of Fabaceae has ten stamens, nine of which have their filaments fused to produce an adelphy state. In contrast, one stamen is free, resulting in a diadelphy condition, or an \[\left( 9 \right) + 1\]arrangement of anthers in the androecium.
Thus, 'Fabaceae' Option C is the correct answer.

Note: TThe Asteraceae are a large and diverse family of plants found in all parts of the world. They are characterized by their \[\left( 9 \right) + 1\]arrangement of anthers in the androecium and their flower heads, composed of many small florets. The Asteraceae are an essential family of plants for their economic value and ecological role.
