$\huge\boxed{\fcolorbox{red}{pin}{Answer}}$

• The sunflower (Helianthus annuus) is a living annual plant in the family Asteraceae, with a large flower head (capitulum). The stem of the flower can grow up to 3 metres tall, with a flower head that can be 30 cm wide.

• They are "perfect" flowers, meaning that they have both male and female producing parts. To prevent inbreeding, the pollen producing structure (the anther) forms a tube around the style of the pistil.
