-Female parts: pistils (with ovary, style, & stigma)

Imperfect Flowers: have either pistils or stamens, but not both

Why do flowers have different aromas? (smells)

• Insects will get pollen on their bodies, and as the insect moves around the flower, it transfers the pollen to other parts of the flower so that fertilization can happen and new seeds can be created
