Biol 1001 Lesson 6 Photosynthesis: Using Light to Make Food 1. A bumper sticker says: “Have you thanked a green plant today?” Interpret this sticker in terms of your understanding of photosynthesis. Plants provide for us oxygen by absorbing and processing carbon dioxide and converting it to oxygen. 2. A friend of yours is wearing a bright red shirt. In terms of properties of light and pigments, explain why the shirt appears red to you. Electromagnetic energy comes to us from the sun in many different wavelengths that our eyes see as different colors. 3. Using fig 7.10b (118) explain why RuBP (ribulose biphosphate) is one of the most common organic molecules in living things. Because the Calvin cycle rearranges the atoms in the 5 G3P molecules, forming three new RuBP molecules; these then start another cycle. Almost a regenerative property. Another reason is that there are millions more photosynthetic organisms (plants , algae, some bacteria, and some protists) that heterotrophic organisms (animals)
