C₄:** **b. CAM:** ### Educational Resource on Photosynthesis#### Understanding T.W. Engelmann's Experiment**Task 5:** In 1882, T.W. Engelmann conducted an experiment to determine the wavelengths of light important for photosynthesis. He placed a strand of *Spirogyra* (a filamentous green alga) across a glass slide. Using a crystal prism, he illuminated the slide with a spectrum of colors. He then introduced a drop of water containing bacteria that required aerobic respiration. Watch the following YouTube video to see his results: [https://youtu.be/Rt37Hyn4Qv4](https://youtu.be/Rt37Hyn4Qv4) **Activity:** Explain the significance of Engelmann's experiment and how it relates to the absorption spectra of chlorophyll a and chlorophyll b.#### Chloroplast Structure and Processes**Task 6:** Label the diagram with the following structures: thylakoid membrane, stroma. Draw arrows to show where water and carbon dioxide enter and where oxygen and sugars exit. Clearly indicate if these substances are entering or exiting the thylakoid membrane or stroma. ***Diagram Description:*** The chloroplast diagram shows an oval-shaped organelle with stacks of disc-like structures (thylakoids) and a fluid-filled space (stroma). #### Photosynthesis Reactions**Task 7:** Identify the location within the chloroplast where light reactions occur.**Task 8:** Identify the location within the chloroplast where Calvin cycle reactions occur.**Task 9:** List two environmental inputs necessary for the noncyclic light reactions: a. b. **Task 10:** Identify the products formed by the noncyclic light reactions. Star (*) the two used in the Calvin cycle reactions. Underline (_) the product considered as "waste": a. b. c. **Task 11:** Identify the initial electron donor and the final electron acceptor in the noncyclic light reactions. Is the final electron acceptor oxidized or reduced? **Task 12:** Explain the role of chemiosmosis in photosynthesis. ---#### ObjectiveThis resource aims to deepen the understanding of critical processes in photosynthesis, focusing on historical experiments, structural components, and the series of reactions occurring within chloroplasts.

14-2. Explain whether the following statements are true or false. Justify the false ones.A. Many, but not all, of the electron transfer reactions involve metal ions.B. The electron transport chain generates an electrical potential across the membrane because it moves electrons from the intermembrane space into the mitochondrial matrix.C. The proton electrochemical gradient consists of two components: a difference in pH and an electrical potential.D. Ubiquinone and cytochrome c are both electron carriers that are easily diffused.E. Plants have chloroplasts and therefore can live without mitochondria.F. Both chlorophyll and the heme group consist of a system of double bonds that allow it to absorb visible light.G. The role of chlorophyll in photosynthesis is equivalent to that of the heme group in the mitochondrial electron transport chain.H. Much of the dry weight of a tree comes from the minerals it takes from the ground at its root.
