Predators target areas which have a high concentration of seeds as they have to spend a lesser amount of time and energy. If all seeds of a plant fall under the parent plant they will grow crowded together and many will die because of lack of space or air, water, sunlight and minerals. The 4 methods of seeddispersalWater,Explosive Action, Wind, Animals. Let’s talk about seed dispersal with this lesson. Description Classroom Ideas. Activity - The children are given images of different seeds. Long distance. Some seeds, like those of the jacaranda, are “flutterers” and have papery edges to help them disperse. Plant seeds can be dispersed in a number of different ways. Long distance seed dispersal (LDD) is a type of spatial dispersal that is currently defined by two forms, proportional and actual distance. Method # I. Dispersal by Wind: For easy dispersal by wind seeds have to be light so that their buoyancy […] The 4 methods of seed dispersal 1. Part of. In order to answer questions on Seed Dispersal correctly, your child needs to know how to link the characteristics of the fruit/seed with the respective seed dispersal method. Seed dispersal. One of the most-amazing examples of wind dispersal is seen in the Javan cucumber, whose seeds are borne in translucent aerodynamic gliders that can be 12 cm (about 5 inches) across! For this activity use your own critical thinking and the lab manual only. Select five of the above mechanisms of seed dispersal (1 point each). Seed dispersal is sometimes split into autochory (when dispersal is attained using the plant's own means) and allochory (when obtained through external means). Duration 01:12. Discuss at least two environmental pressures or characteristics that might have influenced the selection of each type and why that method of dispersal might be advantageous under that pressure. The scattering or spreading of seeds to different places is called seed dispersal. Plants. Types. Therefore, seed dispersal is an essential ecological service. Seed dispersal means the movement of seeds away from the parent plant. ADVERTISEMENTS: The following points highlight the four major methods of dispersal of fruits and seeds. TO be able to be dispersed bywater, a plant seed needs a husk,They are hollow insideThey split open when it reachesthe shoreWater 3. Seed dispersal is essential for plants as it improves the chances of the seeds being able to grow to the adult stage. They must work in groups to discuss the questions and figure out which method(s) the seed uses to disperse. SEED DISPERSAL. The 5 agents of dispersal are : wind, water, eaten by animals, carried by animals and explosion of fruits! The four methods are: (1) Dispersal by Wind (2) Dispersal by Water (3) Dispersal by Animals and (4) Mechanical Dispersal. Science. There are certain characteristic features present in the seeds of various types of plants that help them in getting dispersed by various means/agents. 2. Description.
