HOW ARE THE PLANTS?
1. The parts of the plant.
The plants are formed by the root, the stem and the leaves. The visible parts of the plants are the stem and the leaves. The roots are not seen because they are underground.
Some plants have fruits and flowers.
2. The root.
The root is the part of the plant buried in the ground. The root sets the plant on the ground. It also absorbs water and other substances from the soil.
Some plants have a main, thicker root, from which come several secondary roots. Other plants have all roots of similar size.
3. The stem.
It is the part of the plant that grows above the ground and leaves the leaves. There are two types of stem: woody stem, which is hard and rigid and herbaceous stem, which is soft and flexible.
According to the stem, the plants can be trees, shrubs or grasses. >
- trees have a woody stem. They are formed by a thick stem called a trunk from which the branches are born.
- The shrubs have a woody stem but are very short, and the branches come almost from the ground.
- herbs have the herbaceous stem and tend to be low in height.
The leaves are green parts of the plant that are born from the stem. They have two parts: the petiole and the limbus.
