Multiple Choice

Which statement is accurate about how C ₄ plants are able to survive hot, dry spells during the growing season?

• A) When the stomata close during the heat of the day, RuBP carboxylase(rubisco), which is located in the bundle sheath cells, is not exposed to the increasing oxygen concentration in the leaf spaces. This prevents RuBP carboxylase from binding to oxygen instead of carbon dioxide.
• B) When the stomata close during the heat of the day, RuBP carboxylase (rubisco), which is located in the mesophyll cells,is exposed to the increasing oxygen concentration in the leaf spaces. This help facilitate the binding of RuBP carboxylase to oxygen.
• C) When the stomata are open during the heat of the day, RuBP carboxylase (rubisco), which is located in the bundle sheath cells, is equally exposed to both the carbon dioxide and the oxygen in the leaf spaces.
• D) When the stomata close during the heat of the day, RuBP carboxylase (rubisco), which is located in the bundle sheathcells,is exposed to the increasing oxygen concentration in the leaf spaces. This help facilitate the binding of RuBP carboxylase to oxygen.
• E) When the stomata close during the heat of the day, RuBP carboxylase (rubisco), which is located in the bundle sheath cells,is exposed to the increasing oxygen concentration in the leaf spaces. This help facilitate the binding of RuBP carboxylase to oxygen.
