characteristics of seeds dispersed by wind

Modifications in seed structure, composition, and size help in dispersal. Poppy seeds, for example, can hardly be called aerodynamic, but these plants still depend on the wind. 460) are carried by wind like pollens. Many wetland plant seeds can be dispersed both by surface water and by wind (Bouman and others 2000; Middleton and others 2006; Soons 2006). Some fruit have built-in mechanisms so they can disperse by themselves, whereas others require the help of agents like wind, water, and animals (Figure 1). This makes it easy for the wind to carry them. Larger wind-dispersed seeds are generally heavier and therefore require features such as parachutes or wings to help keep them aloft. Hairy structures, light weight, small size etc. They have special structures that catch the air, such as wings or fluff. They are usually lighter and smaller than other seeds. For example, Dandelion seeds have developed very light and fluffy parachute-like structures. Other plants depend on the wind in different ways. 1. 2. These structures are adaptations in the seeds for dispersal to the remote places. example- cotton seeds, drumstick etc. Seeds that are dispersed by the wind have several characteristic adaptations that allow them to be successful with that strategy. Two examples are the fluffy seeds of the dandelion and the rose-bay willow herb blowing far and wide on the wind. Seeds which have wings and hairy parachutes on them are carried by the wind. This is why plants that use wind dispersal produce so many seeds. Some seeds are very small and light, almost like dust. Examples of different seeds that are dispersed by the wind (Depending on where you live, you may be able to find some of these seeds outside. all over the landscape. Seeds of Cinchona are … Majority of the plants belong to the Asteraceae disperse their seeds by the help of wind. Seeds specially adapted for wind dispersal are characterised by the following: ADVERTISEMENTS: 1. Seeds such as Foxglove are minute and are easily blown about by the wind. 1) Seeds dispersed by wind- Many seeds get dispersed by wind and therefore they may develop hair like structures that offer air resistance so that they are carried over long distances before falling on the ground. How can wind help disperse seeds? An important detail for a wind-dispersed seed is that it is very light.It must be able to float easily on wind or else it will drop straight to the ground. Wind-dispersed fruit are lightweight and may have wing-like appendages that allow them to be carried by the wind. Therefore, the seeds are dispersed by the wind. E.g. Orchid seeds and poppy seeds are like that. Very small, dry and dusty seeds as those of orchids (weighing as little as 0.004 mg in some cases—Fig. – sycamore, ash, maple, lime, dandelion and thistle When pods dry, they split open suddenly and shooting the seeds away from the parent plant and this is easy when the wind is there. help the seeds to disperse by the help of wind. There are "parachutes" on top of some seeds, like milkweed and dandelion seeds. “Salt-and-pepper-shaker” style pods keep the seeds from falling directly below the parent plant. “ Salt-and-pepper-shaker ” style pods keep the seeds are dispersed by the wind in different ways several characteristic adaptations allow...
