Fruits dispersed by wind, like samaras or the achenes of a dandelion, are generally winged (Figure 8.3. 6 ). In the case of a dandelion, each achene is attached to a modified calyx that forms an umbrella-like structure to catch on the wind.

WebThe scattering of seeds or fruits is known as dispersal. There are two reasons for seeds to be dispersed: To prevent overcrowding. Dispersal ensures that the young plants grow far apart from each other. This reduces competition between the young plants and/or with the parent plant for sunlight, water, nutrients and space.
