Why do arctic poppies have flowers that faces the sun?

Arctic poppies have flowers that face the sun to maximize their exposure to sunlight, which is crucial for photosynthesis in the harsh, cold environments they inhabit. By orienting their blooms toward the sun, they can absorb more warmth and light, helping to maintain a higher temperature within the flower and aiding in reproduction. This behavior, known as heliotropism, is particularly beneficial in the short growing seasons of the Arctic, ensuring that they can thrive despite challenging conditions.
