We children of IV, this year we learned that a plant reproduces by seed.
The seeds are produced from the flower, in fact after fertilization, the ovary becomes a fruit that contains seeds. Falling to the ground, the seeds sprout, giving rise to a new map. But how can this happen? 
All 'inside of each seed is an embryo, which has all the facilities inside the new branch: the radicle, the stem and leaves. In addition, each seed may contain one or two cotyledons, ie a reserve of nutrients for the plant, when the seed is the right conditions, it germinates.

From the beginning, the embryo gets nourishment from the seed, then the root starts to push down into the ground, the stem with the leaves come out of the land in search of light and air Sun.
To test this process in class we put in a plastic cup of dried beans with cotton wool, after a few days we noticed that the seed has been opened a little, has slipped in the root and grew a thin cotton stem with the leaves.
