D)florigenesis.
E)vernalization.

Question

Quizplus · Accepted Answer

Thigmomorphogenesis is the term used to describe a plant's response to mechanical stress, which induces changes in the plant's growth and morphology. Trees growing at high elevations experience more mechanical stress due to harsh weather conditions, resulting in shorter and stockier trunks. Thigmotropism refers to a plant's directional growth response to touch and is not directly related to the growth of trees at high elevations. Statolithogenesis refers to the mechanism by which plants sense gravity, florigenesis refers to the flowering process, and vernalization refers to the induction of flowering by exposure to cold temperatures.
