What does the Anther do? • Holds pollen grains
What is the pistil? • The female part of the plant that has the stigma, style, and ovary
What is the style? • The stalklike part of the pistil

Flowers Differ • Complete Flowers: have sepals, petals, stamens, and pistils • Incomplete Flowers: are missing on the the flower parts above
Perfect Flowers: have both male and female parts -Male parts: stamen(with anther and filaments) -Female parts: pistils (with ovary, style, & stigma)
Imperfect Flowers: have either pistils or stamens, but not both
Examples of Complete Flowers • Roses • Hibiscus
Examples of Incomplete Flowers • Squash Flowers & Zucchini Flowers
Seed = an embryo (immature plant) • Largest seed in the world:
Why do flowers have different aromas? (smells) • To attract pollinators (insects, hummingbirds, etc)who eat the flower’s sugary nectar • 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
