Question

Answer

The pappus is the modified calyx, the part of an individual floret, that surrounds the base of the corolla tube in flower heads of the plant family Asteraceae.

Answer

The pappus is the modified calyx. When the calyx is modified to form the hairy or feathery structure and it persists in fruits to allow the dispersal, the calyx is said to be modified into pappus. It is a feature of the family Asteraceae.

So, the correct answer is 'Calyx'

Answer

Pappus is a modified calyx in the Asteraceae family of plants.

Explanation:

- The Asteraceae family of plants, also known as the daisy family, is one of the largest families of flowering plants, with more than 23,000 species.
- One of the distinctive features of this family is the presence of a unique structure called the pappus, which is a modification of the calyx.
- The calyx is the outermost whorl of the flower, consisting of sepals that protect the developing flower bud.
- In Asteraceae plants, the sepals of the calyx are modified into a variety of structures that form the pappus, which is usually located at the top of the fruit.
- The pappus can take different forms, depending on the species, but it often consists of hair-like structures, scales, or bristles.
- The function of the pappus is to aid in the dispersal of the fruit by wind or other means, as it can catch the wind and carry the fruit away from the parent plant.
- Some examples of Asteraceae plants with pappus structures include dandelions, thistles, and sunflowers.

Therefore, we can conclude that Pappus is a modification of the calyx in the Asteraceae family of plants.
