The methods of plant dispersal of seeds include: animal dispersal, wind dispersal, water dispersal, ejection dispersal, bird dispersal, etc.
In nature there are many plants, not sown by humans, but able to multiply more and more, so how do these plants spread the seeds? Let’s get to know it.
Details
01
Animal dispersal: Some seeds stick to other animals, or after being eaten by birds, seeds that are excreted without being fully digested are taken further afield, all of which are dispersing seeds for plants.
02
Wind spread: some seeds grow hair or structure like wings, which will float far away when blown by strong winds, such as dandelion achenes, which grow a lot of long crown hairs, which spread out like a parachute when ripe, spreading the seeds far away.
03
Water transmission: Many plants that grow in or near water usually use water power to spread seeds. Like water lily: When the fruit of water lily matures, it will fall into the water and slowly rot. The seeds covered with spongy outer seed coat will float on the water surface, drift with the waves, and finally sink to the bottom to take root and sprout.
04
Ejection propagation: after the fruit of some plants matures, it is exposed to fierce sunlight for a long time. At this time, as long as it is touched, the fruit will be completely split, and the seeds will be ejected by the elastic force of the peel.
05
Bird dispersal: Birds peck at the fruit and then spit out the seeds. Or after the seeds are swallowed by the bird, they fly farther and then excreted. Plants that transmit seeds by birds are more advanced groups, because birds spread seeds the furthest of all ways.
