Seed dispersal WALT – Explain How plants distribute seeds
7
There are four main ways in which seeds can be dispersed:
Animals Wind Water Explosions
8
Animals Hawthorn Elderberry Blackberry Cherry
Plants use juicy fruits which are carried by birds and other animals. Fruits are eaten, but only the juicy parts are digested. The stones and pips leave the animal's body via the droppings which may be some distance away from the parent plant. Hawthorn Elderberry Blackberry Cherry

1) Why do you think the plant wants the seed to be sown far away from the parent plant? Hawthorn Elderberry Blackberry Cherry

Animals Hawthorn Cherry Elderberry Blackberry
Why do you think the plant wants the seed to be sown far away fro the parent plant? To reduce competition for resources : Water Light Space Nutrients Hawthorn Cherry Elderberry Blackberry

Animals Hazelnuts Burdock Goose Grass Mistletoe
Fruits with hooks and barbs, e.g. the burdock fruit, are carried in the hair, fur and wool of animals. Squirrels bury nuts, including acorns and hazelnuts, for food supplies over the winter, but sometimes leave some behind which may grow into new plants in the spring. Burdock Goose Grass Mistletoe
12
Wind Foxglove Dandelion Sycamore Ash
Plants such as dandelions and foxgloves have fruits with parachutes of hairs that catch the wind and are blown about. Sycamore and ash fruits have wings which can be blown about and carried over distances. Dandelion Sycamore Ash
13
Water Coconut Pond Iris Water Lily
Fruits which float, such as those of the water lily and pond iris are carried by water. Coconuts can also travel for thousands of kilometres across seas and oceans. Pond Iris Water Lily
14
Explosions Broom Laburnum Pea Gorse
Some plants disperse their own seeds. The pods dry and split open suddenly with some considerable force which throws their seeds for some distance. Laburnum Pea Gorse
15
Adaptations For each of the methods, list the way in which the plant/ seed are adapted
16
Adaptations An adaptation is a characteristic that allows a living thing to survive in a particular environment. For example, consider the different ways in which humans and fish breathe. What adaptations can you see in the following plants that help the species to survive by dispersing seeds?
17
Blackberry

Blackberry Blackberries are adapted to be dispersed by animals because they fruit is sweet and the seed is hard and cannot be digested

In your books, choose 2 fruits that we have covered and draw detailed diagrams
1 deispersed by wind 1 dispersed by animal Calculate the magnificationof you drawing Annotate each diagram to explain how the fruit is adapted for it’s type of dispersal
