3. 01 Introduction

4. Introduction Plants are multicellular living beings . They perform the three vital functions: N utrition Interaction Reproduction The differences with the rest of living beings are two: No movement They make their own food

5. 02 Parts of the plant. The root

6. Parts of the plant. The root The root . It is the organ that lies below the ground and lacks leaves It has two main functions 1 Holding the plant to the ground 02 Absorbing water and mineral salts in it Curiosity of the roots The roots can store nutrients so that later the stem and leaves can grow. By storing "food" they thicken their roots (they become "fat") and, at the same time, they are very appetizing for humans Examples of these edible roots are: carrots, beets, turnips, onions, garlic, celery.... Yummy!

7. Parts of the plant. The root The root has several parts A thicker main part It is the axis from which the secondary ones emerge Secondary roots are branches of the main root The purpose of the main root and secondary roots is to hold the plant to the substratum and to transport water and nutrients through the stem to the leaves, but they are not the ones that absorb it Root hairs They are responsible for the absorption of water and nutrients so that the plant can perform the function of nutrition Root cap It is the part that protects the root in the growing zone and is usually found in the lower part of the plant

8. 03 Parts of the plant. The stem

9. Parts of the plant. The stem The stem . The part of the plant that is responsible for holding and transporting water and other mineral substances to all parts of the plant Types of stems according to their hardness Herbaceous stems are thin, flexible and usually green in color. Herbs have herbaceous stems Woody stems are hard, stiff and usually brown in color. Trees have a woody stem called a trunk and their branches usually grow at a certain height from the ground. Shrubs also have a woody stem called a trunk but it is shorter and their branches are usually close to the ground Like the root, it usually divides into secondary stems or branches , from which the leaves, flowers and fruits arise

10. 04 Parts of the plant. Leaves

11. Parts of the plants. The leaves Leaves. They arise from the stem or branches. They are responsible for photosynthesis, respiration and plant transpiration The colors of the leaves They have various colors, depending on the pigment they contain. Those with the most chlorophyll are green Leaf shapes There are many types : lanceolate, elliptical, linear, obovate, oblong, spathulate, rhomboid, reniform, and the list goes on Elliptical Linear Obovate

12. Part s of the plant . The leaves The leaves have two parts The lamina The upper part is the adaxial face and the lower part is the abaxial face . At the center there is a midrib with branches called veins The adaxial face The abaxial face Veins The petiole Part where it joins the stem (there are some that lack this part)

13. 05 Plant nutrition: photosynthesis

14. Plant nutrition: photosynthesis Plants are the only living things that produce their own food. They are called autotrophs. This process is called photosynthesis and for this they need water, mineral salts, carbon dioxide and sunlight 1 In the root, through the absorbent hairs, the plant absorbs water and mineral salts from the soil 02 The mixture of water and mineral salts is transport by the xylem tissue until it reaches the leaves

15. Plant nutrition: photosynthesis Plants are the only living things that produce their own food. They are called autotrophs. This process is called photosynthesis and for this they need water, mineral salts, carbon dioxide and sunlight 03 Leaves take carbon dioxide from the air. The water and mineral salts mixture and carbon dioxide, with the help of solar energy from light, mix to form the plant's food 04 Finally, the plant's food is distributed throughout the plant by the phloem tissue

16. 06 Plant respiration

17. Plant respiration Plants, like all living organisms , breathe During photosynthesis they take in carbon dioxide and expel oxygen . This happens during the day, which is the oxygen that the rest of the living beings consume! That's why they are called "the lungs of the planet" But they also breathe (during the day and night) and consume oxygen and expel carbon dioxide. Don't panic! Their oxygen consumption is minimal. They are still our lungs Carbon dioxide Oxygen

18. 07 Goodbye

19. Goodbye We hope you have understood the importance we have on planet Earth. Without us, it would be difficult for you to live Take care of us and we will take care of you!
