Group 4 photosyntheis Final Presentation-MSP

  1. 1. PHOTOSYNTHESIS GROUP 4 Light Energy and Plants
  2. 2. Learning Objectives • By the end of this lesson, students should be able to: -explain that the process of photosynthesis converts light energy to chemical energy. - explain that the sun is the original energy source for most life on earth. -identify the reactants and products of photosynthesis. -explain which reactions in photosynthesis are light dependent which are light independent. -explain why many plants appear green to us here on earth.

  3. 3. Colors/Visible Light S8P4. Students will explore the wave nature of sound and electromagnetic radiation. a. Identify the characteristics of electromagnetic and mechanical waves. b. Describe how the behavior of light waves is manipulated causing reflection, refraction diffraction, and absorption. c. Explain how the human eye sees objects and colors in terms of wavelengths. d. Describe how the behavior of waves is affected by medium (such as air, water, solids). e. Relate the properties of sound to everyday experiences. Colors/Visible Light S8P4.

  13. 13. • The green color comes from chlorophyll in the chloroplasts • Chloroplasts absorb light energy and convert it to chemical energy Light Reflected light Absorbed light Transmitted light Chloroplast THE COLOR OF LIGHT SEEN IS THE COLOR NOT ABSORBED
  14. 14. • Photosynthesis is the process by which autotrophic organisms use light energy to make sugar and oxygen gas from carbon dioxide and water AN OVERVIEW OF PHOTOSYNTHESIS Carbon dioxide Water Glucose Oxygen gas PHOTOSYNTHESIS
  15. 15. Photosynthesis • Occurs in chloroplasts • The green color comes from chlorophyll in the chloroplasts • Chlorophyll is the green pigment that captures light for photosynthesis • The pigments absorb light energy and create sugar and oxygen
