Multiple Choice
Which statement is accurate about how C4 plants are able to survive hot, dry spells during the growing season?
A) When the stomata close during heat stress, RuBP carboxylase is not exposed to the increase in oxygen concentration experienced in the leaf. This allows the plant to avoid photorespiration.
B) When the stomata close during heat stress, RuBP carboxylase is exposed to the increase in carbon dioxide concentration experienced in the leaf. This allows the plant to avoid photorespiration.
C) When the stomata open during heat stress, RuBP carboxylase is not exposed to the increase in oxygen concentration experienced in the leaf. This allows the plant to avoid photorespiration.
D) When the stomata close during heat stress, RuBP carboxylase is exposed to the increase in oxygen concentration experienced in the leaf. This allows the plant to undergo photorespiration.
E) When the stomata open during heat stress, RuBP carboxylase is not exposed to the increase in oxygen concentration experienced in the leaf. This allows the plant to undergo photorespiration.
