#1. This article mentions the role of a proton pump in regulating the opening of stomata when exposed to sun. Where in the process of photosynthesis is a proton gradient produced to encourage the formation of ATP? (Hint: It is a portion of the Light Reaction of photosynthesis.)
#2. The article describes the importance of getting carbon dioxide to enter the leaf. Based on what you have learned for Chapter 8 material, what is the name of the portion of the photosynthesis process that utilizes carbon dioxide?
#3. When stomata are open, they permit carbon dioxide to enter the leaf, but they also permit the loss to the atmosphere of a substance that is necessary for the Light Reaction portion of photosynthesis. What is this substance?
#4. There are two evolutionary adaptations present in various plants that survive well in hot, dry environments have developed. What are the two names used in the textbook to refer to plants that have one or the other of these adaptations?
#5. The researchers suggest that their findings can contribute to increased plant growth and providing food for our planet’s growing population. Based upon what you know about the problems faced by plants when stomata are open, what is a limiting factor that might hamper increased food production by increased stomata opening?
#6. The authors of the paper suggest that their findings may contribute to sustainability by addressing concerns regarding carbon emissions that have accumulated in our atmosphere as a result of burning fossil fuels. How would using the research findings help address high atmospheric carbon accumulations?
#7. Based upon your knowledge of cell membranes, which of the 4 types of organic molecules is embedded in the cell membranes of stomata guard cells to carry out the proton pump function described in paragraph 3 of the research article?
