There are several ways to disperse seeds (what are the methods for plants to disperse seeds)
Every life reproduces in its own way. Cows and horses have feet, and birds have wings. As immobile plants, nature also endows them with a special way of spreading seeds. So what are the ways in which plants disperse their seeds? Let’s take a look at how these plants spread their seeds.
Animal transmission
The plants that disperse seeds through animals include cocklebur, terrestris, ghost needle grass, mountain grapes, pine trees, cherries, pine nuts, chestnuts, etc. Seeds such as ghost needle grass and cocklebur are covered with barbed hairs and barbs, which will stick to the fur of animals when touched lightly. Most plants such as cherries and wild grapes have fleshy fruits. After the fruits of these plants are eaten by birds, the seeds pass through the digestive tract and are excreted freely everywhere. Chestnuts, pine nuts, etc. The squirrels will carry them home for storage, some of them will be eaten, and the rest will take root and sprout in the coming year.

The plants that spread their seeds by wind include dandelion, willow, poplar, maple and so on. The seeds of these plants are usually light enough to be suspended in the air. A light blow of the wind can take them to the ends of the earth. Some plant seeds also grow some special structures suitable for flying by the wind, such as the fine hairs on the seeds of cotton and willow, the umbrella-shaped crown hairs on the dandelion fruits, and the wing-like structures of the seeds of pine, maple, and elm trees.
Water Transport
Plants that grow in or near water usually disperse their seeds by water, such as coconut trees and water lilies. When the fruit of the coconut tree is ripe, its shell is hard, like a boat drifting with the sea, and new coconut trees will grow after being washed ashore by the tide. After the water lily fruit matures, it will fall into the water and slowly rot. The seeds covered with the spongy exocarp will float up, drift with the current on the water surface, and finally sink to the bottom of the water to take root and germinate.
Jet propagation
Ejection means that the seeds are ejected like cannonballs. Common seeds are canola, mustard greens, peas, soybeans, mung beans, sorrel, and impatiens. When the seeds of these plants are ripe, their dry, hard skins tend to burst when baked in the hot sun, and the seeds are catapulted far away like bullets from the chamber of a gun. One of the most interesting is a plant called “spray melon”. When the melon is ripe, it will fall off with a light touch, and the seeds in the melon will be sprayed out from the top in an instant.
