Daisies are herbaceous plants, which means that they have soft, green stems and leaves. The leaves of a daisy are arranged in a rosette, which is a circular pattern.

The flowers of a daisy are made up of many small petals that are arranged in a disc-like shape. The centre of the flower is made up of tiny, yellow florets.

AQA Science Exam Question and Answer

Question:

Daisies are known for their phototropic behaviour. Explain what phototropism is and how daisies exhibit this phenomenon in response to light.

Answer:

  • Phototropism is the growth movement of plants in response to light. It is a vital survival mechanism, as it helps plants optimise photosynthesis by positioning their leaves or flowers in the direction of the light source.
  • In the case of daisies, their phototropic behaviour is evident in their flowers. During the day, when sunlight is available, daisy flowers exhibit positive phototropism, leaning towards the direction of the sun. This positioning allows the flowers to capture more sunlight, enhancing their photosynthetic activity and reproductive success.
  • However, at night or in low light conditions, daisies showcase negative phototropism. Their flowers close and face downwards, protecting the delicate reproductive structures from cold temperatures and potential herbivore damage.
  • In summary, phototropism is the light-induced growth response in plants, and daisies demonstrate this phenomenon by positioning their flowers to maximize light absorption during the day and protect their reproductive structures at night.
