In these pods the seeds are arranged in four rows and the flat lens-shaped seeds have peculiar hood-like projections, called jaculators or retinacula, from their funicles which straighten out during dehiscence so that the four rows of seeds are ejected cross­wise in four different directions. Many mistletoes have explosive fruits with sticky seeds to (hopefully) propel their parasitic offspring high into neighboring trees. 3. This is called dispersal by explosive. Smart videos for curious minds of all ages, This site uses cookies to improve your experience. Some plants, like peas, gorse and flax, have seedpods that dry out once the seeds are ripe.

Edible fruits, specially those that are brightly colo­ured, are devoured by various animals and, in many cases, their seeds pass through animal alimentary canals without any injury. 469E), Cleome viscosa, etc., possess sticky glands so that they stick to the faces and bodies of grazing animals and are thereby dispersed. Welcome to BiologyDiscussion! (i) Pappus (Figs. L. Whitby; 2 Which method of dispersal does this seed use? The same purpose is served by the inflated ovaries of the pod of Colutea arborescens (Leguminoseae) and the capsules of the balloon vine (Cardiospermum halicacabum) and also a few other plants of Sapindaceae (Fig. Miss. 462) is a tuft of hair developed as a crown on the seeds of Calotropis, Holarrhena, Alstonia (two tufts) and most plants of Apocynaceae and Asclepiadaceae. Some plants distribute their seeds by violently ejecting them so that they fall well away from the parent plant. If all seeds of a plant fall under the parent plant they will grow crowded together and many will die because of lack of space or air, water, sunlight and minerals. Fruits of Tribulus are provided with sharp spines-enabling them to stick to cattle hoofs. Seeds dispersed by water are contained in light and buoyant fruit, giving them the ability to float.

For easy dispersal by wind seeds have to be light so that their buoyancy may enable them to float on air over long distances. This is important because if the seeds are not dispersed, many germinating seedlings will grow very close to the parent plant… This dehiscence is accompanied by the expression of great force in many fruits so that seeds are jerked a considerable distance away from the mother plant. This is of special importance in seashore plants like the coconut which has migrated thousa­nds of miles in the Pacific and Indian Oceans floating on the sea waves from island to island. 1.
