Spread of seeds and fruits – simply explained
Do you know why dandelion seeds fly around so wonderfully? It's because the plant spreads with the help of the wind. In this video, you'll learn about different mechanisms for seed and fruit dispersal. You now know that not only the wind, but also water, animals, and people play an important role.
You'll also find a worksheet and interactive exercises on the topic of seed and fruit dispersal. So you can test your newly acquired knowledge right away!

As you already know, after fertilization, plants produce seeds. These contain the plant's seedlings, which can later develop into fully grown plants themselves. To spread, a plant tries to spread its seeds over as long distances as possible.
There are plants that produce free seeds after fertilization (gymnosperms) and others whose seeds are enclosed in a fruit (angiosperms). Depending on whether the plant is a gymnosperm or angiosperm, the free seeds or the enclosed seeds disperse with the help of their fruit.
