Slide 4

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 ovule

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.
