Is called germination to the germination act . The concept comes from the Latin word germinatio. He verb germinate , meanwhile, refers to begin to develop or sprout.
If we focus on the botany field, the idea of germination is linked to the development of a plant from the seed : that is, from the part of the fruit that houses the embryo of a new specimen.
Germination, therefore, is a process that begins with the embryo development and reaches the birth of a plant . In order for germination to occur, certain conditions of temperature, availability of water and nutrients, etc. are needed. The seed must also be in the right medium. Once the process is triggered, if it is deployed successfully it will culminate in the appearance of a new plant.
For the seed to form, a anterozoid (male gamete) must reach the ovary and enter the Ovum (female gamete). There the concrete fertilization and the ovule ends up becoming a seed, while the ovary takes the form of fruit.
Germination happens to a resting phase and involves the resumption of embryo growth, which is dry. With the supply of water, the embryo swells until it manages to break the seed envelope. Thus arises the outbreak, which begins with the appearance of the radicle . In the case of phanerogam plants, the first leaf of the embryo is called cotyledon : upon receiving the sun's rays, the cotyledon can develop the photosynthesis and so the plant subsists and grows.
He process Germination is usually part of the elementary school program. It is a very suitable experiment to get the children of the city to approach nature and see with their own eyes how their food grows, for example. Needless to say, in the countryside, agriculture-oriented education is very common, and in homes they learn these and other things since childhood.
Parents can do the experiment germination on their own, without waiting for teachers to demand it from their children, since it is an excellent opportunity to share with them the magic that the life cycle entails, not so different between plants and us. It is normal to use a bean, since it germinates quite easily, although this does not mean that it does not require attention and care.
Through the germination experiment, it is easier to know each of the parts of the plant, since we see step by step how they form. In addition, it is ideal for develop patience, love and respect from children to other living beings, three essential values to integrate into society in a healthy way. Another aspect of the person who is reinforced by germination is the responsibility : If we neglect the seed for too long, the experiment is spoiled.
The materials needed for germination are beans, a glass jar, cotton and Water . First the cotton is placed in the jar, without crushing it. Then, the beans, leaving enough space between one and the other. Next, the cotton should be moistened slightly. Finally, we must locate the bottle where it receives sunlight. Cotton should be moistened once a day throughout the entire process.
In a matter of days, if everything goes well, several plants are born and develop very quickly. After a week from the beginning, we are likely to be able to plant the shoots in the earth so that they continue growing in the most natural way possible.
