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 - 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 ...

Seed dispersal distances of mother plant is a basic aspect in plant life history, and have great effects on plant ecology, evolution and conservation. Seed dispersal modes of species can often be recognized by morphological characteristics of fruits and seeds.

Results. Variation in seed and fruit morphology is caused in part by selection for dispersal capabilities [].Wings and plumes, as well as fleshy, juicy, and nutritious tissues, have each arisen many times across a broad taxonomic range [], and they originate in a variety of histological layers of the testa, pericarp, and adjacent tissues. The ingenious ways plants disperse their seeds - Seed dispersal There is no animal alive that eats the avocado seed, and its too big to be transported by wind. It is believed to have evolved to be carried by a now extinct species. Dispersal is the process of organisms spreading from one place to another. All species, including plants, maintain or expand their range through dispersal. Seed dispersal Facts for Kids - Kiddle encyclopedia Many grass seeds have surfaces which catch onto passing creatures. For instance spear grass has spiky tips that can get stuck in passing animals or blown by a strong wind to a new place. Another way for animals to help in seed dispersal is for the animals to actually plant the seeds themselves.

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 Dispersal of Seeds by Wind - The Seed Site

This is why plants that use wind dispersal produce so many seeds. Other plants depend on the wind in different ways. Poppy seeds, for example, can hardly be called aerodynamic, but these plants still depend on the wind. “Salt-and-pepper-shaker” style pods keep the seeds … Gone with the Wind: Plant Seed Dispersal - Scientific American
