Pollination Fertilization Germination Angiosperm Reproduction 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.
Flower Anatomy 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 flower’s 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
PISTIL female reproductive part receive pollen contain ovules STAMEN male reproductive part produce pollen PETALS attract insects and other animals SEPALS modified leaves that protect the bud NECTAR M ost 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. Flower Anatomy OVULES egg cells within the ovary 3 1 2 4 5
Anthers Stargazer lily
Anther Structure that produces and h olds pollen Stamen Male reproductive part; i ncludes both an anther and a filament Filament Thin stalk that holds up the anther
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.
Sepals modified leaves that protect the developing bud
Male/Female Some plants produce only male flowers. Some plants produce only female flowers. Some have both and can self-pollinate. stamen pistil
