Why is wind dispersed?
Wind is very important for dispersing seeds to help plants reproduce. In this project you will design some of your own “seeds” and see which ones work best when they are blown across the room by a fan. Dispersal of seeds is very important for the survival of plant species.
What is an example of wind dispersal?
Wind dispersal 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. Some plants, like kauri and maple trees, have ‘winged’ seeds.
What happens during wind dispersal?
Dispersal of Seeds by Wind. Some tall trees produce seeds with stiff wings covering the seed that enable them to fly long distances. The wings are twisted and balanced so that the seed spins around as it is carried along by the wind.
What fruit is dispersed by wind?
Some fruits, such as the dandelion, have hairy, weightless structures that are suited to dispersal by wind. The remarkable Protea Family (Proteaceae) of Australia contains some truly amazing genera with winged seeds, including Banksia and Hakea. They don’t float away but flutter to the ground.
Is coconut dispersed by wind?
Wind-dispersed fruit are lightweight and may have wing-like appendages that allow them to be carried by the wind. Seeds dispersed by water are contained in light and buoyant fruit, giving them the ability to float. Coconuts are well known for their ability to float on water to reach land where they can germinate.

Which plants are dispersed by wind?
The seeds of the orchid plant, dandelions, swan plants, cottonwood tree, hornbeam, ash, cattail, puya, willow herb, are all examples of plants whose seed are dispersed by the wind.
Is mango dispersed by wind?
Most of the mango seeds are dispersed by animals, birds, and humans.
How are mangoes dispersed?
Mango – Most of the mango seeds are dispersed by animals, birds, and humans. The flesh of mango fruits are eaten by the animals and birds and they drop the edible part on the ground. Elephants and other large animals act as a seed dispersal because they swallow the whole fruit and excreted out as droplets of dung.
Is mango an Indehiscent?
Drupe or stone – a fleshy indehiscent simple fruit that develops from a simple ovary, with the layers of the pericarp distinctly separated. The endocarp which encloses the seed is hard and woody or stone-like. In most fruits, the mesocarp is fleshy when ripe (e.g. mango).
How are tomatoes dispersed?
Tomato seeds can be dispersed by birds and foraging animals. Animals excrete the undigested seeds miles away from the original plant. Half-eaten fruit was often carried and dropped miles away from the original plant. Wildlife readily dispersed tomato seeds throughout countries such as Bolivia, Chile and Peru.
