Flowering Plants

Anther Anther = the top of the stamen (male reproductive structure) and produces pollen *Pollen grains contain the male gametes *Usually many stamen on each flower

Anther Filament Filament = a stalk that supports the anther

Anther Filament Stem

Petal Anther Filament Stem Petals = coloured leaf-like structures of most flowers *organisms that pollinate flowers are attracted to the coloured petals Stem

Petal Stigma Anther Filament Stem Stigma = sticky part that receives a pollen grain Stem

Petal Stigma Anther Style Filament Stem Style = tube-like structure where pollen grain travels down to Stem

Petal Stigma Anther Style Filament Ovary Stem Ovary = where eggs contained Stem

Petal Stigma Anther Style Filament Ovary Sepal Stem Sepal = tiny leaf-like structures that protect the flower Stem

Pollination = process where pollen moves from male structures to the female structures Can be moved via wind, insects, birds, or mammals (Cross pollination) Other plants can pollinate themselves (Self pollination)

Seeds and Eggs

Seeds In plants, the ovary becomes the fruit Once egg fertilized in the ovary, it is called a seed Seed contains embryo + stored food

Seed Anatomy

Eggs Most animals lay eggs Eggs that are laid contain: Zygote, nutrients, and mechanism of protection

Amniotic Eggs Eggs of reptiles and birds that contain single embryo surrounded by a shell Embryo cushioned by amnion (fluid-filled sac) Allantois holds wastes produced by embryo Chorion controls movement of wastes

Amniotic Egg

Eggs Many types of prenatal care of eggs Birds keep eggs warm by sitting on them Sea turtles dig holes in sand, lay eggs, bury When eggs hatch, hatchlings crawl to ocean
