Question

Quizplus · Accepted Answer

Jewelweed plants exhibit adaptive phenotypic plasticity in response to competition from other plants by growing longer stems to reach sunlight and avoid shading. This is a common response to competition for resources in plants. A) Developing trichomes and glucosinolates is a response to herbivore pressure rather than competition from other plants. B) Growing shorter stems would not be an adaptive response to competition as it would decrease the plant's ability to access sunlight. D) Closing stomata in leaves may be a response to water stress rather than competition from other plants.
