GROWTH OF THE PLANTS

The plants grow all their life. In order to grow plants need to feed. To carry out photosynthesis, plants absorb water through their roots with mineral salts that are in the floor. This mixture called crude sap, ascends the stem of the plant and reaches the leaves

There, chlorophyll captures sunlight, transforms carbon dioxide from air, water and salts into essential nutrients for the plant: sugars. The plant releases oxygen.

One of the ways to know the age of a tree, in the areas that have the four seasons is, in its cut trunk, count the number of rings that it presents. Each ring represents a year of life. This method is used to determine the age of a dead and already cut tree; It would be foolish to kill a tree to know its age.

REPRODUCE AND DIE

All the plants have the capacity to have other plants that are their daughters. 

The ability to reproduce exists from the moment it has reached its final form and has reached the state of maturity. Each species of plant reaches maturity in a certain time. That is why there are herbal species, for example, that take a few weeks while certain species of trees can take a few years until the time comes when they can reproduce.

There are plants that can reproduce without seed. The mother plant emits horizontal stems called stolons. New daughter plants grow from the tips of the stolons that immediately root, that is, they emit small roots that allow them to anchor in the ground and be a plant independent of the mother plant. An example of this way of reproducing is  the strawberry.

Death is the end of the life of a plant and therefore it is also the last stage of its life cycle. Each species has its own life time.

When the plant dies it dries and its remains are used by other living beings. When a plant dies others usually of the same species, take their place. Plants are living things because they do  the life cycle.
