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) Germination When a dormant seed falls under the conditions needed for it to sprout into a new plant.
Flower Anatomy FLOWERS 30. Why do some plants have flowers? What is their main function? To help the plant reproduce (by attracting pollinators) sepals 31. In a flower, modified leaves called ________ protect the bud. 32. The broad, flat, thin leaf-like parts of a flower, called petals ________, attract insects and other animals. 33. A male flower’s reproductive structure is a(n) stamen pistil _______ and the female structure is a(n) ovary ovule develops into a fruit, and the _______ 34. If the egg is fertilized, the _______ develops seed.
Flower Anatomy PETALS attract insects and other animals 1 PISTIL female reproductive part STAMEN male reproductive part • receive pollen • contain ovules 2 • produce pollen 3 OVULES egg cells within the ovary 4 NECTAR Most flowers use some of their sugars to produce nectar, which they use to lure in pollinators. Insects move from flower to flower eating nectar while unwittingly transferring pollen at the same time. SEPALS modified leaves that protect the bud 5
Anthers Stargazer lily
Stamen Male reproductive part; includes both an anther and a filament Anther Structure that produces and holds pollen Filament Thin stalk that holds up the anther
Pistil Female reproductive part; includes stigma and style, and ovary. Stigma Tip of the pistil; pollen sticks to it. Style Tube connecting stigma to ovary. Ovary Contains ovules (unfertilized eggs); eventually grows into the fruit.
Sepals modified leaves that protect the developing bud
Male/Female Some have both and can plants self-pollinate. Some stamen produce only male flowers. pistil Some plants produce only female flowers.

Layers of a Leaf A. B. C. D. E. F. G. H. Cuticle Epidermis Stomata (guard cells) Palisade layer Vein Spongy layer (air space) Xylem Phloem
Photosynthesis Review What is the entire Photosynthesis Equation? 6 CO 2 + 6 H 2 O light chlorophyll C 6 H 12 O 6 + 6 O 2
Pollination and Fertilization What does this become? Pollen grain forms on anther Pollen tube forms Sperm fertilized the ovule (egg) to produce a new seed.
