Bacteria to Plants Angiosperms

Vascular Plants Seedless Gymnosperms Angiosperms Reproduce with spores Example: ferns “Naked Seeds” Reproduce without protective fruits Example: pine “Covered Seeds” Reproduce with flowers and seeds covered by fruits Example: Apple

Angiosperms What characteristics do angiospermss share? What are the structures of a flower and what are the function of an angiosperm’s flower? How do angiosperms reproduce?

Structure of Flower Flowers are used for reproduction

Sepals

Structure of Flower Sepal: leaf-like structure/often green Protects developing flower

Petals

Petal: usually most colorful part of flower Structures of a Flower Petal: usually most colorful part of flower Size, number, shape vary Attract pollinators

Stamen

Stamen: male reproductive parts of flower Structure of Flower Stamen: male reproductive parts of flower

Anther

Structure of Flower Anther: produces and stores pollen Filament: slender stalk that supports anther

Pistil/Carpel

Pistil: female reproductive part of flower Structure of Flower Pistil: female reproductive part of flower

Stigma

Structure of Flower Stigma: sticky tip of pistil; attracts pollen Style: slender tube that connects stigma to hollow base

Structure of Flower

Structure of Flower Ovary: hollow area at base of flower; contains ovules that will become seeds
