3 Angiosperm Reproduction Pollination Process of the pollen (sperm) getting from one flower to another (carried by a pollinator)Fertilization Sperm coming into contact with the ovule (egg)GerminationWhen a dormant seed falls under the conditions needed for it to sprout into a new plant.
4 To help the plant reproduce (by attracting pollinators) Flower AnatomyFLOWERS30. 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.

Insects move from flower to flower eating nectar while unwittingly transferring pollen at the same time.5
7 Stamen Male reproductive part; includes both an anther and a filament Anther Structure that produces and holds pollenFilament Thin stalk that holds up the anther
8 Pistil Female reproductive part; includes stigma and style, and ovary. Tip of the pistil; pollen sticks to it.StigmaStyleTube connecting stigma to ovary.OvaryContains ovules (unfertilized eggs); eventually grows into the fruit.
