- Discuss Concepts Concerns about global climate change and the greenhouse effect center on rising levels of greenhouse gases, including atmospheric carbon dioxide. Plants use CO for 2 photosynthesis, and laboratory studies suggest that increasedCO2 levels could cause a rise in photosynthetic activity. However, as one environmentalist noted, What plants do in environmental chambers may not happen in nature, where there are many other interacting variables. Strictly from the standpoint of physiological effects, what are some possible ramifications of a rapid doubling of atmospheric CO2 on plants in temperate environments? In arid environments?Which type of reproduction, sexual or asexual, might be more beneficial in the following circumstances and why? (a) a perennial (plant that lives more than two years) in a stable environment (b) an annual (plant that lives one year) in a rapidly changing environment (c) a plant adapted to an extremely narrow climate rangeFigure 4 shows an open stoma during a gaseous exchange process in a plant.
