In some cases the seeds may remain hanging by their red or orange-coloured funicles from the open legume, the coloured funicle and aril acting as a bird attractant. Seed dispersal is the way seeds get away from the parent plant to a new place. If the wind is right, seeds from these plants can travel hundreds of miles. The birds disperse the seed while its passage through the bird's gut may assist in germination. Thus, drumstick plant has winged seeds. Seeds which have wings and hairy parachutes on them are carried by the wind. Some seeds dispersed by water. Most seeds don’t fall in suitable growing locations. Maple seeds with their twin propellors get ready to launch. It follows that it is an evolutionary advantage to get their seeds away from the parent plant. Seed dispersal is the movement, spread or transport of seeds away from the parent plant. Dispersal of seeds means to scatter seeds over a wide area. Acacia seeds are dispersed mostly by being ejected from the legume when it opens, usually under the influence of the hot sun. This is why plants that use wind dispersal produce so many seeds. This is called dispersal of seeds. Seeds from plants like dandelions, swan plants and cottonwood trees are light and have feathery bristles and can be carried long distances by the wind. With wind dispersal, the seeds are simply blown about and land in all kinds of places. Seeds of the cotton and dandelion have tiny hairs surrounding them. Plants, obviously, cannot move after they have put down roots. Seeds specially adapted for wind dispersal are characterised by the following: ADVERTISEMENTS: 1. Some seeds dispersed by wind. Very small, dry and dusty seeds as those of orchids (weighing as little as 0.004 mg in some cases—Fig. Plants have limited mobility and rely upon a variety of dispersal vectors to transport their propagules, including both abiotic vectors such as the wind and living vectors like birds.Seeds can be dispersed away from the parent plant individually or collectively, as well as dispersed in both space and time. – 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. Similarly, the seeds of maple plant also have wings which help in their dispersal by the wind. Ash trees seeds just have one wing so they don’t spin in the same way but do waft along on the wind long enough to get out of their parent’s shadow. Passing animals and people do their part to disperse sticky seeds like burdock and sea holly. They don’t float away but flutter to the ground. (b) The seeds of madar (aak) have hair which allow them to be carried away easily by the wind.T he fruits of sunflower have hair which enable them to be blown away by wind and get dispersed. It’s a big gamble though. Some plants, like kauri and maple trees, have ‘winged’ seeds. There are maple keys that spin and fly, cottonwood seeds that float gently, and dandelion seeds that fly along like tiny parachutes. For easy dispersal by wind seeds have to be light so that their buoyancy may enable them to float on air over long distances. The maple seeds have wings attached to it. These adaptations enable the seeds to be carried by the winds. Hitchhikers. The basic idea is as follows. 460) are carried by wind like pollens. "Dispersal" means to spread or scatter. E.g.
