Sexual Reproduction • two parents • male gamete • female gamete • genetic variation
pistil stamen petals receptacle sepals
sepals Sepals • outermost appendage of a flower • protect the flower while it is developing and after the flower buds • usually green
Petals • usually colorful • attract pollinators
stamen Stamen • the male reproductive structure
Stamen • the male reproductive structure • the long filament which bears the anther
filament Filament • the stalk of the stamen
anther Anther • the saclike structure that produces and stores pollen
Pollen • the male gamete
pistil Pistil • female reproductive part of a flower • consists of three main sections: ovary, style, and stigma
ovary Ovary • contains the ovules, which are the female gametes • matures into the fruit that surrounds the seeds
Stigma • expanded tip of the carpel • receives the pollen stigma
style Style • slender stalk • between stigma and ovary
Gametes • male gamete pollen • female ovule
pollination the process of transferring pollen from an anther to a stigma
zygote seed • seed plant
seed coat stored food
pollen tube tube that grows from pollen on a stigma, down the style, and into the ovary of a flower
ovule contains the female gamete
fertilization the formation of a zygote from the union of two gametes
fruit the ripened ovary of a flower
Asexual Reproduction • the production of a new organism without the joining of gametes • reproduction that takes place by mitotic cell division
prophase interphase metaphase anaphase telophase cytokinesis complete
Asexual Reproduction • runners with plantlets • root sprouts • leaf cutting • stem cutting • root cutting
