To help children learn more about seeds and their dispersal mechanisms, try some of the experiments and questions below. Floating or flying seeds. Many seeds, like dandelions, cottonwoods, milkweed and cattail are light and have adaptations that allow them to be easily carried by the wind. Do any of the seeds have a "better" design than others? Fruit and Seed Dispersal | Biology for Majors II Some fruit have built-in mechanisms so they can disperse by themselves, whereas others require the help of agents like wind, water, and animals (Figure 1). Modifications in seed structure, composition, and size help in dispersal. Wind-dispersed fruit are lightweight and may have wing-like appendages that allow them to be carried by the wind. Seed Dispersal Answer - Zephyrus Wind dispersal: dandelions have fruits with parachutes of hairs that catch the wind and are blown about. Sycamore fruits have wings which can be blown about and carried over distances. 2. Water dispersal: fruits which float, such as those of the water lily and the coconut palm are carried by water. Coconuts can travel for thousands of ... (PDF) Seed Dispersal - researchgate.net
A. Dispersal by Wind: Wind plays an important role in the dispersal of some fruits and seeds. Plants which require wind as an agent are called anemochorous. For wind dispersal, the seeds should be light in weight, so that their buoyancy may help them to fly for long distance.
Seeds that are small in size and light in weight are dispersed by wind. Cotton, Madar, and dandelion seeds are dispersed by wind. They have fine, long hair ...

Life cycle of a plant | Science & Nature | National Geographic Kids Wind: other plants have specially adapted seeds that are dispersed by the wind. One such plant is the dandelion, which has feathery parachutes attached to its ... Grassland biodiversity is blowing in the wind -- ScienceDaily
Seed Dispersion And Seed dispersal methods - botanystudies.com
Wind seed dispersal is also known as air seed dispersal. Seeds on plants that are programmed to undergo wind dispersal are very light and are somewhat similar to feathers. The unique appearance and characteristics of the leaf allow the wind to carry the seeds long distances. An example of a plant that undergoes wind seed dispersal is a dandelion. Dispersal of Fruits and Seeds | Essay | Angiosperms | Botany A. Dispersal by Wind: Wind plays an important role in the dispersal of some fruits and seeds. Plants which require wind as an agent are called anemochorous. For wind dispersal, the seeds should be light in weight, so that their buoyancy may help them to fly for long distance. Dispersal of Seeds by Wind - The Seed Site Dispersal of Seeds by the Wind. Wind is one of the main agencies of seed dispersal. The way it transports them depends on the type of seed and where it grows. Fruits and Seed Dispersal Free Essays - PhDessay.com Fruits and Seed Dispersal Nicole Saylor Meiko M. Thompson BIO 115 11/25/12 In this essay I will be answering questions about fruit and as to the reason why things are the way they are… First up is some fruits are sweet and some are not is because, "Actually, the taste of a fruit depends on the compounds present in it.
DISPERSAL BY WIND. The dispersal of seeds by the wind takes place in the following way: Minute seeds. The orchids and grasses seeds are minute in size and weigh around 0.004 g, hence they can easily be dispersed by wind. Winged seeds. The seeds are provided with wing like projections, which are easily carried by wind. e.g. Jacaranda, Moringa ...

What is the importance of wind in seed dispersal - answers.com
The paper "How the Seeds for Later Self-Government Were Sown in the Early Colonies" discusses that different European colonies in the new world of America built their economies according to their geographic location and natural resources available to them. … Orchid seeds: Nature's tiny treasures | Kew At the time of dispersal, orchid seeds consist of a spindle-shaped, wafer-thin seed coat that encloses an extremely small and simplified embryo in the shape of a spherical cluster of cells. Just one single cell layer thick, the seed coat (also called testa) forms a balloon around the embryo, a clear adaptation to wind dispersal. Seed Dispersal - Maggie's Science Connection Some animals bury seeds, like squirrels with acorns, to save for later, but they may not return to the seed later, so it can grow into a new plant. 3. Wind dispersal The kind of seeds which are often wind dispersed are smaller seeds that have wings or other hair-like or feather-like structures. Plants that produce wind blown seeds, like a ... examples of lab reports for biology - cheapgetwritingessay.com One of the seed dispersal mechanism is by wind, the seed is carried in their fruits and dispersed away from the parent plant depending on various factors such as the nature of the wind and physical characteristics of the seed/fruit. Seed dispersal is important for the continued survival of a plant species.Writing a Biology Lab Report A special ...
