Reproduction in flowering plants

Parts of a flower

• Stamen (male): anther (makes pollen) + filament.
• Pistil/carpel (female): stigma, style, ovary (with ovules).
• Petals attract insects; sepals protect the bud.

Pollination

Transfer of pollen from anther to stigma.

• Insect-pollinated: large bright petals, scent, nectar, sticky pollen, stigma inside the flower.
• Wind-pollinated: small dull petals, light smooth pollen, feathery stigma hanging out (maize, grass).
• Self (same flower or plant) vs cross (different plant).
