Flowers the reproductive structures of plants
4 parts of a plant • Roots • Stems • Leaves • Reproductive (includes flowers and fruits)
Flowers have 4 different parts • Sepals • Petals • Stamens • Pistil
Pedicel • The flower stem
Receptacle • The place on the stem where floral organs attach and originate.
Sepals • Usually green; leaflike structures that protect the flower, as it forms and emerges.
Calyx • The group of sepals on a flower
Petals • Located just inside the sepals • Leaf-like and often very colorful • Attract pollinators
Corolla • The collection of petals on a flower
Perianth • The sepals and the petals of a flower. (Not the reproductive parts.)
Tepals • When there is no clear distinction between the sepals and the petals...they are called “tepals”.
The reproductive parts • Found at the center of the flower
Stamens • Male reproductive parts of a flower • Arranged around the female parts
Anther • Part of the stamen • Produces and holds pollen
Filament • Stalk that holds up the anther
Pistil • The female part of the flower
Stigma • Found at the end of the pistil • Has a sticky surface to catch pollen
Style • The neck of the pistil
Ovary • Part of the pistil that contains the ovules
Ovule • The part of the flower in which the eggs are produced and seeds develop
Complete flowers • Have all 4 basic parts: • Sepals, petals, stamens and pistil
Incomplete flowers • Flowers that are missing one of the four basic parts
Perfect Flowers • Flowers that have both male and female parts
Imperfect flowers • Flowers that lack one of the sex structures
