Flowers: Structure & Fertilization: 

Flowers: Structure & Fertilization Mr. Haskell 10/1/07

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


Plant 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
