Is named germination to the act of germinating. The concept comes from the Latin word germination. The verb germinate, for its part, refers to starting to develop or sprout.
If we focus on the field of botany, 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 it reaches the birth of a plant. 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 successfully deployed 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 fertilization and the ovule ends up becoming a seed, while the ovary takes the form of a fruit.
Germination occurs at a resting phase and supposes the resumption of the growth of the embryo, which is dry. With the contribution of water, the embryo swells until it manages to break the envelope of the seed. Thus arises the outbreak, which begins with the appearance of the radicle. In the case of phanerogamic plants, the first leaf of the embryo is called cotyledon: when receiving the sun’s rays, the cotyledon can develop the photosynthesis and so the plant subsists and grows.
The process Germination is often part of the elementary school program. It is a very suitable experiment to get the children of the city to get close to nature and see with their own eyes how their food grows, for example. It goes without saying that agriculture-oriented education is very common in the countryside, and they already learn these and other things at home from a young age.
Parents can do the experiment germination on their own, without waiting for the teachers to demand it of their children, since it is an excellent opportunity to share with them the magic that the cycle of life supposes, not so different between plants and us. The normal thing is 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 how they are formed step by step. In addition, it is ideal for develop patience, love and respect of children towards other living beings, three essential values to integrate into society in a healthy way. Another aspect of the person that is reinforced through 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 slightly moistened. Finally, we must place the jar where it receives sunlight. The cotton must be moistened once a day throughout the process.
In a matter of days, if all goes well, several plants are born and they develop very quickly. After a week from the beginning, it is likely that we can sow the sprouts in the ground so that they continue to grow in the most natural way possible.
