Male Female:
Male Female Stamen-reproductive organ:filament & anther
Anther-produces pollen, contains sperm
Filament-stalk holding anther
Pistils-reproductive organ:stigma, style, & ovary
Stigma-receives pollen
Style-stalk that connects the stigma to the ovary
Ovary-contains ovules, has seeds inside
Slide6:
Plant Fertilization
Fertilization:
Fertilization Pollen (male) produces a “pollen tube” so the sperm can reach the egg (female) in the ovule.
Nucleus Divides:
Nucleus Divides Pollen nucleus divides into two sperm nuclei
1=sperm nucleus + egg zygote (baby
plant)
2=sperm nucleus + regular cell endosperm
Zygote + endosperm == seed
Slide11:
