Pollination Fertilization Germination Process of the pollen
(sperm) getting from one flower to another (carried by a
pollinator) Sperm coming into contact with the ovule (egg) When a
dormant seed falls under the conditions needed for it to sprout
into a new plant.

FLOWERS 30. Why do some plants have flowers? What is their main
function? 31. In a flower, modified leaves called _______________
protect the bud. 32. The broad, flat, thin leaf-like parts of a
flower, called _______________, attract insects and other animals.
33. A male flowers reproductive structure is a(n) _____________ and
the female structure is a(n) _____________. 34. If the egg is
fertilized, the ______________ develops into a fruit, and the
_____________ develops into a seed. To help the plant reproduce (by
attracting pollinators) sepals petals stamen pistil ovary

which they use to lure in pollinators. Insects move from flower to
flower eating nectar while unwittingly transferring pollen at the
same time. OVULES egg cells within the ovary 3 1 2 4 5

Anther Structure that produces and holds pollen Stamen Male
reproductive part; includes both an anther and a filament Filament
Thin stalk that holds up the anther
Slide 9
Stigma Style Ovary Pistil Female reproductive part; includes
stigma and style, and ovary. Tip of the pistil; pollen sticks to
it. Tube connecting stigma to ovary. Contains ovules (unfertilized
eggs); eventually grows into the fruit.

Some plants produce only male flowers. Some plants produce only
female flowers. Some have both and can self-pollinate. stamen
