Question

Identify the incorrect statements from the following:
P) Cymose inflorescence is found in Hibiscus
Q) Hypanthodium is found in Ficus
R) Synandrous stamens are found in Calotropis
S) Hesperidium type of fruit is found in Mango

Answer 1

The inflorescence of cymose is distinguished on the basis of a flower that is present at the apex of the flower axis. A specific form of inflorescence is Hypanthodium. The receptacle here is fleshy and, with an apical opening, forms a hollow ball-like shape. The stamens seem fused over the whole length as both the anthers and filaments are fused. It is known as Synandrous. A hesperidium with a rough, leathery rind is a modified berry.

Complete answer:
First we should know about inflorescence to answer this question. Many different features, including how the flowers are arranged on the peduncle, the flowering order of the flowers, and how different clusters of flowers are clustered among them, characterise inflorescences. As plants in nature may have a combination of forms, these concepts are general depictions. These structural results were based primarily on natural selection.

Now, let us find the solution from the options-

The main flowering stalk ending in a flower is distinguished by cymose inflorescence and the peduncle stops rising. The development of flowers from lateral buds results in this. In addition, the flowers display basipetal succession in this form of inflorescence, with the oldest at the apex and the youngest at the base. Hibiscus, periwinkle etc. are examples. Thus, the statement P is correct.
Hypanthodium is a specific kind of inflorescence where the fleshy peduncle shapes as a hollow cup with an apical opening with sessile flowers inside. For example, Ficus. Thus, the statement Q is correct.
In Synandrous stamens, anthers and filaments are joined in the same whorl as in Cucurbita maxima. Thus, the statement R is incorrect.
The fruit form of Hesperidium is a berry which has a strong aromatic rind which can be seen in Citrus medica and Citrus sinensis (orange). Thus, the statement S is incorrect.

Thus, the correct answer is option (B) P,Q.

Note: Inflorescence is the modified portion of the seed plant shoot where flowers are produced. A multiple or a composite fruit is considered a fruit that grows from a complete inflorescence. There are two major types of composite fruits, Sorosis and Syconus.
