  3. Objectives LESSON OBJECTIVE ENABLING OBJECTIVES ENABLING OBJECTIVES • Demonstrate the process of respiration • Demonstrate the processes of photosynthesis After completing this lesson on plant processes, students will demonstrate their ability to apply the concept in real-world situations by obtaining a minimum score of 80% on the picture perfect plant process booklet evaluation. 01 02 Demonstrate the processes of photosynthesis Summarize the processes of absorption and translocation of nutrients in the plant 03 04

  4. Key Terms Photosynthesis Xylem Respiration Phloem Transpiration Absorption Translocation

  5. Think – Pair – Share What processes sustain human life versus plant life?

  6. Objective 1Demonstrate the processes of photosynthesis, respiration, and transpiration

  7. Photosynthesis Photosynthesis is the process in which plants convert carbon dioxide and water into sugar and oxygen.

  8. Components of Photosynthesis oxygen carbon dioxide • CO2 = • H2O = • C6H12O6 = • O2 = water glucose

  9. Photosynthesis Formula ____ _____ Light Energy H2O O2 C6H12O6 CO2 6 ____ + 6 ____  _______ 6 ___ ________ Chlorophyll

  10. Environmental Factors

  11. Test Your Knowledge

  12. What does the word “photosynthesis” mean? Answer: It is a Greek word that has two meanings. Photo means light and synthesis means putting together. It means that sunlight, water and carbon dioxide all have to come together and work together in order for energy and oxygen to be generated as products to be given off.

  13. What essentials do plants need? Answer: Light, water, nutrients, soil, etc… Light is from the sunlight, water from ground and carbon dioxide from the air.

  14. What are xylem tubes? What are they similar to? Answer: Xylem tubes are like blood vessels in a human. They transport vital nutrients to the plants.

  15. What is a stomata? Answer: A stomata is an opening on the plant leaf surface. They are responsible for exchange of gases in and out of the plant.

  16. Can photosynthesis take place underwater? Explain. Answer: Yes, it just takes place at a much slower rate because the rays of light must pass through the water before being absorbed by the leaf surface of an aquatic plant.

  18. Objective 2Demonstrate the process of respiration

  19. What is Respiration? • After photosynthesis has allowed CO2 and water to be converted to sugar and oxygen, the energy must be released so that the plant can use the energy to grow. Respiration is the method by which the energy is released and used and is the reverse of photosynthesis– the controlled breaking down of glucose, releasing energy for plant growth, absorption, translocation, and other metabolic processes.

  20. Respiration Respiration is a basic life process that: • Enables plant cells to release energy that is then used in many energy-requiring chemical reactions within cells • Releases water and CO2 into the atmosphere • ATP is the energy that is produced from the cellular respiration process

  21. Objective 3 Demonstrate the process of transpiration

  22. Think About It How do human bodies cool off?

  23. 3-2-1 Review

  24. Objective 4Summarize the processes of absorption and translocation of nutrients in the plant.

  25. What does it mean for something to be absorbed?

  26. Plant Absorption Hair roots take up water and dissolved minerals from the soil through the process of osmosis. Water moves from the roots and through the plant via the xylem vessels.

  27. Translocation • The vascular system of a plant is a channel for water and food to move through the system of the plant. • Movement of water and nutrients within plant • Occurs within vascular system: • Xylem tissues pull water upward • Phloem tissues move food from leaves to the rest of the plant

  28. Absorption & Translocation

  29. Conclusion Photosynthesis, respiration, absorption, translocation, and transpiration are the five plant processes necessary in the development of healthy plants. It is important to know about these plant processes and how they can be encouraged and manipulated in the production of better plants.
