Question

method of seed dispersal write 5 points on it

Answer 1

Seeds are dispersed away from each other and from the parent plant so that there is less competition. The commonest methods of seed dispersal are:

wind e.g. dandelion, sycamore fruits are light and have extensions which act as parachutes or wings to catch the wind
animal internal e.g. tomato, plum, raspberry, grape have brightly coloured and succulent fruits which contain seeds with indigestible coats which allow the seeds to pass through the animal undamaged
animal external e.g. goose grass, burdock, the fruits have hooks which attach them to the fur of passing animals.
explosive/ self propelled e.g. pea pod. The pod burst open when ripe projecting the seeds away from the plant.
