The largest and heaviest wind-dispersed seeds, such as Sycamore cannot rely on hair-like parachutes to keep them airborne. They would have to be enormous to be effective. Instead they have developed a wing which causes them to spin through the air like mini helicopters. ... Rarely are all such seeds eaten.

How do sycamore plants disperse their seeds?
What do the seeds of ash, sycamore and maple trees have in common? They all are enclosed in a wing-like structure that helps them disperse - away from the parent plant and indeed each other. Wind dispersal is also known as anemochory.
How do sycamore reproduce?
Sycamore produces compact balls of tiny, single-sex flowers. The males and the females are in separate parts of the same tree. Wind pollination is the rule. When fertilized, the females develop into a round cluster of very light 1-seeded achenes.
Why do sycamore seeds spin through the air?
Why do sycamore seeds spin? When the helicopter shaped seed falls the air pushes upwards against it. ... The two arms get pushed in opposite directions, which makes the seed spin. This helps sycamore seeds to fall far from the tree so they have plenty of space to grow.
How does sycamore get dispersed Class 5?
Sycamore seeds are carried away by the wind.
What are the 4 mechanisms for seed dispersal?
The most common methods are wind, water, animals, explosion and fire. Dandelion seeds float away in the wind. To make sure at least some of the seeds land in a suitable growing place, the plant has to produce lots of seeds.
What type of seed dispersal mechanism do you think sycamore seeds use?
Seeds dispersed by the wind are easier to investigate than seeds dispersed by other methods. For example, you could release sycamore seeds and measure the distance they travel. Factors that could affect the distance travelled by a sycamore seed include: the surface area of the wings.
Can you bonsai a Sycamore?
It is said that Sycamore Maple, the forest giant, is not quite tameable and the idea of giving it the shape of a bonsai can be quite difficult. a) Positioning – Acer Pseudoplatanus must be positioned in a place where it can receive good sunlight during morning and evening.
Why does the bark fall off trees?
Usually, it's normal for a tree to lose bark. ... Bark falls off after frost, which usually happens on the tree's south or southwest side. Any sudden swing in temperature can make trees shed bark and crack under stress. Bark falls off after excessive heat, which, like frost damage, strips bark down to the wood.
Why do sycamore trees lose their bark?
The bark is brittle and can't accommodate the fast growth and annual diameter accruals of the trunk and branches, so it cracks and exfoliates. According to the United States Forest Service, low winter temperatures may injure the bark and cause excess sloughing.
Can you eat samaras?
Are Maple Seeds Edible? The helicopters, also called whirligigs, but technically known as samaras, are the outer covering that must be removed when eating seeds from maple trees. The seed pods under the covering are edible. After peeling the outer covering of the samara, you'll find a pod containing the seeds.
Why do Sycamore seeds fall?
Well-Known Member. Surely it must depend on the wind a lot. Sycamore seeds are the 'aeroplanes' which spin round as they fall. The majority would be around the tree where not so many would grow due to competition from the mother tree but if the wind was blowing as they fell then they could be in a much larger area .
Is a Sycamore a maple?
The Sycamore is a member of the maple family, known formally as the Aceraceae. (The Latin genus name Acer means sharp, and is a reference not to the form of the tree itself but to its timber. Wood from maple trees, including sycamores, was used for making spears.)
What is seed dispersal explain?
Seed dispersal is the mechanism by which plant seeds are transported to new sites for germination and the establishment of new individuals. Animals commonly mediate this process, and consequently, the ultimate fate of seeds depends on their effectiveness as seed dispersers.
Why does dispersal of seeds take place?
Dispersal of seeds is very important for the survival of plant species. If plants grow too closely together, they have to compete for light, water and nutrients from the soil. Seed dispersal allows plants to spread out from a wide area and avoid competing with one another for the same resources.
How do plants travel?
Plants may not have feet, but they do move! Plants travel by sending out seeds and fruit that fall on the ground and begin growing where they fall. Sometimes seeds are designed to travel long distances before they find soil to grow in, such as dandelion seeds that are blown far away by the wind.
