What spreads seeds by the sun?

There are many ways to spread seeds, such as wind transmission, water transmission, ejection transmission and so on.

What spreads seeds by the sun?

The plants that rely on the sun to spread seeds are peas, soybeans, hemp, melon, impatiens, clover, chestnut, cruciferous plants and so on. Among them, peas are dried in the sun, and then explode and pop out to spread. Impatiens is when the fruit is dried by the sun, the fruit will crack, and then put the seed bullet in all directions.

Second, what are the ways in which seeds are transmitted?

1. Wind propagation

Plants that rely on the wind to spread their seeds: dandelion, Artemisia annua, a little red, bitter wheatgrass, Reed and so on. The seeds of these plants are relatively light, and each seed has fluffy fibers or thin wings. As soon as the wind blows, it begins a walk-and-go journey. When it comes to the right soil and climate, it will take root and sprout and grow into new plants.

2. Animal transmission

Plants that rely on animal fur to spread seeds: Xanthium sibiricum, peach blossom, Bidens bipinnata, inverted buckweed, etc. The seeds of these plants have barbed thorns on the outside, stick to human clothes or animal fur, and take them to a distance to spread the seeds.

3. Ejection propagation

The seeds of some plants, relying on their own explosive power, spread the seeds, such as fried soy sauce grass, impatiens, sesame, and most beans such as red beans and mung beans. These seeds generally have a shell, and when the seed is ripe, the shell fiber will become dehydrated and tight, and the shell will burst as soon as the wind blows, ejecting the seed.

4. Hydraulic transmission

Plants that spread their seeds by the flow of water: coconuts, lotus seeds, Euryale seeds, etc. These plants generally grow on the edge of the water, and the seeds have a hard shell. After maturing, it falls into the water, floats with the waves, is washed to the shore and takes root and sprouts.

5. Bird transmission

Most of the seeds transmitted by birds are fleshy fruits, such as berries, drupes and cryptic fruits. Birds peck at the seeds of Lauraceae and spit them out. After the fruit is eaten, the seeds pass through the digestive tract and are excreted at will. Plants that rely on birds to spread seeds are a relatively advanced group, because birds spread seeds the farthest of all ways.
