What plants propagate by seeds and how they spread

Plants meet us at every step. The person uses them in different industries: not only for food, but also for making clothes, furniture, and also for creating comfort and beauty. More than 200 species are now cultivated by humans. And the main value in human life is seed plants, mainly flowering plants. They are grown on fields and vegetable gardens. And so for amateur gardeners and flower growers it is very important to know which plants multiply seeds. After all, this method is the simplest and cheapest.

History of Seed Breeding

The first plants on Earth were spreading spores. But this mechanism turned out to be imperfect, since a very small number of disputes fell into favorable conditions. Therefore, to date, only ferns, mosses and lichens have survived. The emergence of a huge variety of plants nature is due precisely to the appearance of the seed method of reproduction. After all, a seed that has a protective shell and a supply of nutrients is more adapted to harsh conditions, can lie for a long time and wait until animals or humans transfer it to the soil favorable for growth.

The first seed plants are conifers, ginkgoids and sagovnikovidnye. They are still very common on Earth. A very large group is angiosperms, or flowering plants. They not only provide a person with food and clothing, but also decorate his life. Therefore, everyone will be interested to know which plants reproduce by seeds.

Structure of seed plants

The peculiarity of all of them is that at least once in their life they form a flower, in the place of which the fruit with seeds ripens. Beauty, aroma and coloring of it depend on the method of pollination. The main parts of such plants are pestle and stamens. Each flower is different. Stamens contain pollen and are necessary for pollination of flowers. Pestle consists of ovary, post and stigma. It is in the first that the fruit develops with the seeds.

All plants are divided into single-seeded and many-seeded. Seeds vary in size, color and shape. They can be small, like dust, or large and hard (for example, beans or acorns). From all that has been said, it can be inferred that seeds multiply plants that have flowers.

How the seeds spread

During the evolution of nature, invented many ways to spread them. After all, for the survival of plants it is important that the seeds scatter over long distances. They must germinate under favorable conditions. If you know which plants multiply seeds, it becomes clear that the latter can not be the same. After all, many of them have a special structure, which depends on the way they are distributed.

1. Most seeds are spread by the wind. In some plants, they are therefore very small, like dust. Other seeds have special devices to fly long distances. For example, the maple fruit is called "lionfish" and when rotated it rotates, so it blows away very far from the wind. Poplar and dandelion seeds are fluffy and light. They are covered with small hairs, and the dandelion still has the shape of a parachute.
2. Very many seeds are spread by humans or animals. They have the devices to cling to clothing or wool and are thus carried over long distances. This, for example, is a string or burdock. Some seeds are sticky and stick to everything, even to the paws of birds.
3. Often, plants that reproduce with seeds have juicy and tasty fruits. They are eaten by birds or man, and the bones fall into another place.
4. There are also plants that throw away their seeds, often over long distances, such as a rabid cucumber. The yellow acacia does the same.

How to grow plants from seeds

There are a lot of lovers of indoor flowers now. But rarely one of them is interested in what plants reproduce by seeds. It's a cheap, but rather troublesome way. Seeds must first be soaked, then sown in a favorable soil for them. It is necessary to create special conditions: optimum temperature, humidity and illumination. After germination, it is important to water them in time, put them in a sunny warm place, thin out sprouts. Therefore, most growers prefer to buy ready-made seedlings.
