Water dispersal. 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. 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. Modifications in seed structure, composition, and size help in dispersal. Plants disperse their seeds which are carried and spread through various means like wind, tagging to animals, birds and also water. Ans : a) The seed dispersal is the scattering of seeds away from the parent plants. 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. With wind dispersal, the seeds are simply blown about and land in all kinds of places. The seed dispersal is very crucial to the survival of plants. Wind Dispersal: When wind is used to disperse either pollen or seeds. Other plants depend on the wind in different ways. Many plants have seeds that use water as a means of dispersal. Most common dispersal mechanism. • Wind dispersal of seeds. The phenomenon of Seed Dispersal helps in reproduction in plants. Dispersal of seeds is important for the continued survival of a plant species. “Salt-and-pepper-shaker” style pods keep the seeds from falling directly below the parent plant. Some plants even shoot the seeds out explosively. Flowering plants have different adaptations to enable their seeds to be dispersed as far away as possible. b) The advatages of wind method is that it … The wind is the natural and fundamental means of seed dispersal in the plant kingdom. 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. The seeds float away from the parent plant. Seed size is an important factor. The methods of seed dispersal are : wind , water and insects. The dispersal advantage demonstrates the strategies plants have evolved to make sure sperm are delivered from one plant to another. 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). 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!. 80. Wind-dispersed fruit are lightweight and may have wing-like appendages that allow them to be carried by the wind. They may be carried by wind, water or animals. Seed dispersal 1. Pollinating animals are attracted to prominent and colorful flower petals. If plants grow too closely together, they compete for light, water, and soil nutrients; therefore, seed dispersal is a way to distribute offspring. This process of dispersal is mainly seen in those plants which bear very light seeds. Seed diSperSal 2. Seed Dispersal by Wind . For example, since many fruits are edible, animals and birds may play a role in increasing angiosperm seed dispersal. This is why plants that use wind dispersal produce so many seeds. 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. Poppy seeds, for example, can hardly be called aerodynamic, but these plants still depend on the wind. Ever wondered how seeds from one Plant get sown in a different area altogether?
