Agents of dispersal Name of the seed/Fruit By wind Cotton seeds By water Coconut seeds By animal Sunflower seeds By bird Bignonia seeds By man Burdock seeds By gravity Apple seeds Seed dispersal is the movement, spread or transport of seeds away from the parent plant to ensure the germination of seeds into an adult plant. The seeds that are light-weighted are carried through the wind from one place to another. The seeds that are dispersed by water are capable to float on the water. These are mainly seen in those plant that lives in water or nearby the water bodies. A few animals and birds eat the entire fruit and only the juicy part is digested by their system and the seed are excreted out in the form of their dropping, which forms into new plants. Spikes and hooks of the seed entangle in the feather of animals and therefore help in the seed dispersal. Seeds are dispersed by humans during farming, irrigation, etc. Gravity is the force of attraction towards the earth surface. As the fruit ripens, it falls on the ground due to the force of attraction, they sometimes roll down to some smaller distance, get buried in the soil after a few days and germinate into a new plant.
