While genetics provide the blueprint for development, environmental factors dictate the actual outcome. Light is perhaps the most critical factor; through the process of photomorphogenesis , plants adjust their growth patterns based on light intensity and duration. For instance, the phenomenon of etiolation occurs when plants are grown in darkness, resulting in pale, elongated stems as the plant searches for light. Temperature also plays a vital role, particularly through vernalization , where exposure to prolonged cold is required to trigger flowering. Additionally, the relative lengths of day and night (photoperiodism) determine the timing of flowering, ensuring reproductive success aligns with favorable seasons.
