The Age Of Trees

Trees grow in height, in width and in depth. The trunk becomes thicker, adding a new layer of wood beneath the bark each year. These layers form concentric rings and so, by counting these rings, we can find out the age of a tree.
The thickness of each ring indicates the weather conditions in which it grew. The rings are wider in case of rain and sun, thinner if the tree has suffered drought.

Perfumed Flowers

Flowers are perfumed because their petals contain essential oils, widely used in the manufacture of perfume. The oil of the rose, violet and jasmine are the ones most widely used, for medicines and disinfectants, as well as perfume.

A flower’s perfume also attracts pollinating insects, such as bees and wasps. However, there are some flowers which have an unpleasant smell.
