PLANT STATION #13Seed dispersalSeed development was a major factor in the success of angiosperms and gymnosperms. Seeds offer protection and nutrition of the embryo. Angiosperm seeds have an advantage over gymnosperm seeds by having a fruit surrounding the seed. This fruit is instrumental in the dispersal of the seed. 1. There are four types of seed dispersal: explosive, wind, animal and water. Go to the following web site on the computer and fill in the chart.
