Which of the following flower(s) move in the direction of sun?
Answer: Sunflower
Explanation:
The correct answer is option B: Sunflower. Sunflowers are known for their ability to move or turn their heads to face the sun. This movement is called heliotropism and it allows the sunflower to maximize its exposure to sunlight.
Here are some key points about sunflowers and their movement towards the sun:
- Heliotropism: Sunflowers exhibit a behavior known as heliotropism, which means they track the movement of the sun across the sky.
- Sunflower heads: The large flower heads of sunflowers follow the path of the sun from east to west during the day.
- Growth and development: Sunflowers are young plants in the morning and they face east. As the day progresses, the flower heads slowly turn and face west, following the movement of the sun.
- Maximizing sunlight: By facing the sun, sunflowers are able to maximize their exposure to sunlight. This is important for photosynthesis, the process by which plants convert sunlight into energy.
- Importance for pollination: Facing the sun also helps attract pollinators, such as bees, to the flower heads. This increases the chances of successful pollination and seed production.
In conclusion, sunflowers are the flowers that move in the direction of the sun. They exhibit heliotropism, turning their heads to face the sun and maximize their exposure to sunlight for growth, development, and pollination.
