How many sepals does a marigold have?

What is a pappus?
Pappus, in a composite flower, is the element of the individual disk and ray flowers that surrounds the flower structure, in the same manner at the base as calyx does in a non-compound flower. Pappuses may be like bristles, teeth or scales and are usually too diminutive to discern without some type of magnification device. The etymology of this name is that it derives from the Ancient Greek word pappos, Latin pappus, meaning old man, but also used for a plant - assumed to be an Erigeron species - having bristles, and also for the woolly, hairy seed of certain plants.

How do dandelions change into puffs?
Dandelions change into puffs through a process called seed dispersal. After the bright yellow flower blooms, it matures into a spherical seed head composed of numerous tiny seeds attached to fine, hair-like structures called pappus. When the seeds are ready, the flower head dries out and the pappus expands, allowing the lightweight seeds to be carried away by the wind. This adaptation helps the dandelion spread and grow in new locations.
Number of petals of marigold flower?
Marigold belongs to the family Asteraceae (Compositae) where flowers are born on Head or Capetulum. In each flower there are five fused petals and the sepals are modified in to several haie like structures known as Pappus.

His contributions to projective geometry.
How does goats beard from a dandelion get dispersed?
The goat's beard, or dandelion seed, is dispersed primarily through wind. Each seed is attached to a fluffy, parachute-like structure called a pappus, which allows it to be carried away by even the slightest breeze. When the seed matures and the flower head dries, the pappus helps it float away from the parent plant, enabling it to colonize new areas. This wind dispersal mechanism increases the chances of germination in suitable environments.

How do you construct an arbelos pappus chain?
To construct a Pappus chain within an arbelos, begin by identifying the three semicircles that define the arbelos, which are formed by three tangent circles. From the points where these semicircles touch, draw circles tangent to each other and to the sides of the arbelos. The centers of these tangent circles will form a chain, known as the Pappus chain, which can be extended infinitely. This construction utilizes the unique properties of the arbelos and the relationships of tangency among the circles.
What are dandilion seeds called?
Dandelion seeds are commonly referred to as "puffballs" or "dandelion parachutes." They are actually the fluffy, white seed heads that form after the yellow dandelion flower blooms and matures. Each seed is attached to a fine, hair-like structure called a pappus, which helps it disperse in the wind.
How does the fruit dandelion help in the dispersal of its seeds?
Dandelion seeds are attached to a feathery structure called a pappus, which acts like a parachute, allowing them to be carried by the wind to new locations. When the wind blows, the pappus helps the seeds to float away from the parent plant and cover greater distances for dispersal.
