UNIT 5 PLANTS 1. THE CHARACTERISTICS OF A PLANT
Plants make their own food.
They usually have roots, stems and leaves.
They do not have senses.
They are usually green.
They can react to their surroundings but they do not move from one place to another.
They usually reproduce from seeds.
2 - THE PARTS OF A PLANT. Almost all plants have three parts: the roots, a stem and leaves. 1. The roots are under the ground and support the plant. They absorb water and minerals from the soil. 2. The stem grows up from the soil and supports the leaves. Water and minerals pass through the stem to the leaves. 3. The leaves grow from the stem and branches and are usually green.

3. - HOW PLANTS FEED
1. The plant absorbs water and minerals from the soil through its roots. 2. They go up through the stem to the leaves. 3. The leaves absorb carbon dioxide from the air. 4. In the leaves, the plant uses energy from The Sun and the substances it absorbs to make its own food.
4. - HOW A PLANT REPRODUCES
To reproduce, most plants grow flowers. Flowers grow in the spring. We can see the parts of a flower in the picture. The plant reproduces by growing a fruit from the flower. The seeds are inside the fruit. When the fruit falls to the ground a new plant can grow from the seed.

5. - TYPES OF STEMS. HARD STEM: Plants with a hard stem are called woody.
4
SOFT STEM: Plants with a hard stem are called herbaceous.
6. - DO YOU KNOW? Most plants are green. They are green because of a substance called chlorophyll which is in leaves and soft stems. Chlorophyll is very important. It takes energy from The Sun so the plant can carry out photosynthesis.
7.- HOW A PLANT GROWS. Plants need lots of sunlight and water and the right kind of soil to grow. During the life of a plant: The stem grows taller and thicker. Branches grow from the stem. The roots grow down into the ground. They divide into smaller roots, like branches. The leaves get bigger and new leaves grow. The plant grows fruit and reproduces.

8. - TYPES OF PLANTS. There are many different types of plants. One way we can classify them is by size: Grasses, or herbs, are the smallest plants. Grasses have a green, thin, flexible stem. Bushes, or shrubs, are bigger than grasses. Bushes have a thin, woody stem, which divides into branches close to the ground. Trees are the biggest plants. Trees have a thick, woody stem called a trunk, with branches that grow high above the ground.
Vegetation is the name we give to all the different plants that grow in a particular place.
