If plants grow too closely together, they compete for light, water, and soil nutrients; therefore, seed dispersal is a way to distribute offspring. • Wind dispersal of seeds. The methods of seed dispersal are : wind , water and insects. To help their chances that at least some of the seeds land in a place suitable for growth, these plants have to produce lots of seeds. Wind-dispersed fruit are lightweight and may have wing-like appendages that allow them to be carried by the wind. The phenomenon of Seed Dispersal helps in reproduction in plants. Seed diSperSal 2. This process of dispersal is mainly seen in those plants which bear very light seeds. Pollinating animals are attracted to prominent and colorful flower petals. Seed dispersal 1. For example, since many fruits are edible, animals and birds may play a role in increasing angiosperm seed dispersal. The dispersal advantage demonstrates the strategies plants have evolved to make sure sperm are delivered from one plant to another. Dispersal of seeds is important for the continued survival of a plant species. Parachutes include seeds or achenes (one-seeded fruits) with an elevated, umbrella-like crown of intricately-branched hairs at the top, often produced in globose heads or puff-like clusters.The slightest gust of wind catches the elaborate crown of plumose hairs, raising and propelling the seed into the air like a parachute. They may be carried by wind, water or animals. The seeds float away from the parent plant. The wind is the natural and fundamental means of seed dispersal in the plant kingdom. Seed Dispersal by Wind . 80. 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). The different methods of seed dispersal are… by wind by animals by water by explosion Reproduction in plants — getting the seeds dispersed Seed Dispersal 3. Click on the links below to find out more. This strongly reminds us of our biology classes where reproduction was a major topic and also the spreading of seeds. Wind Dispersal: When wind is used to disperse either pollen or seeds. Most common dispersal mechanism. Ever wondered how seeds from one Plant get sown in a different area altogether? Water dispersal. Plants disperse their seeds which are carried and spread through various means like wind, tagging to animals, birds and also water. Some plants even shoot the seeds out explosively. The seed dispersal is very crucial to the survival of plants. “Salt-and-pepper-shaker” style pods keep the seeds from falling directly below the parent plant. Flowering plants have different adaptations to enable their seeds to be dispersed as far away as possible. Advantages and Disadvantages of Seed Dispersal The dispersal advantage demonstrates the strategies plants have evolved to make sure sperm are delivered from one plant to another. Poppy seeds, for example, can hardly be called aerodynamic, but these plants still depend on the wind. This is why plants that use wind dispersal produce so many seeds. Seed size is an important factor. Modifications in seed structure, composition, and size help in dispersal. Ans : a) The seed dispersal is the scattering of seeds away from the parent plants. Many plants have seeds that use water as a means of dispersal. With wind dispersal, the seeds are simply blown about and land in all kinds of places. Other plants depend on the wind in different ways. For example, since many fruits are edible, animals and birds may play a role in increasing angiosperm seed dispersal. You can also access an activity sheet related to seed dispersal, or try out the Ranger's Puzzle Page, with Wordsearch, Crossword and Ranger's bad joke!. b) The advatages of wind method is that it … Used to disperse either pollen or seeds hardly be called aerodynamic, but these plants still depend on links.
