Document Summary
Seed dispersal is plants getting off their newborn seeds to a good start in life, these are the advantages. Avoiding crowding and competition with the mother plant. Gives the offspring a better chance of survival as they will not all be in one place. Plants protect their seeds until they are mature. Cones have physical protection (the cone itself) Terpenoids are used to protect the seeds. Aposematic colouration (warns predators, don"t eat me i"m not ready) Resin, a terpenoid, is used for chemical protection. Berries are pale in color and taste bitter when they are not ready to be consumed. Milkweed seeds are protected by the pod that holds the seeds that are full of cardiac. Plants have multiple ways of sending off their seeds, so that the seeds can grow into plants. Anemochory is wind dispersal of seeds and is used by plants that grow in open sunny areas.
