Question

What part of the flower is often scented to attract insects and animals?

Answer 1

Plants use floral scents in their floral tissues like their petals. The floral scents start as organic chemicals known as volatile organic compounds (VOC).

Explanation:

The insects and animals that visit these flowers are drawn in by the chemoreceptors, which create a olfactory response in animals to draw them in to the flowering plant. Floral scents have many VOCs in their petals.

Flower petals also draw in pollinators through the color of their petals, not only the scent. Depending on the insect or animal, the color can attract more of that species.
