plant parts

stamen male reproductive part of a plant
anther yellow pouch that holds pollen grains (contains sperm)
filament fine hair-like stalk that supports the anther
pistil female part of a plant
stigma sticky surface at the top of the pistil
style tube like structure that holds up stigma
ovary base of the pistil that contains ovules
ovules part of the ovary that becomes the seed (contains egg cell)
sepal leaf like parts of the plant that protects the buds
pollination process by which pollen travels from a stamen to a pistil.
pollination occurs 2 ways: wind and insects/animals
fertilization the joining of a sperm and egg cell.
steps of fertilization: 1) pollen grain lands on stigma 2) pollen tube grows down style to ovary 3) sperm travels down tube and unites with egg cell in ovary
after fertilization: 1) fertilized egg cell is the embryo that becomes the plant 2) the ovule becomes the seed 3)the ovary becomes fruit
