Flower Morphology

Flower Anatomy

Structure: Flowers- missing parts Floral Parts Structure Reproduction Sepals, Petals, Complete Perfect Stamens, Pistil Sepals, Stamens, Incomplete Perfect Pistil Sepals, Stamens Incomplete Imperfect

Parts of the Flower Sepals Outer covering of the flower bud. Protects the stamens and pistils when flower is in bud stage. Collectively known as the calyx.

Parts of the Flower Petals Brightly colored Protects stamen & pistils. Attracts pollinating insects. Collectively called the corolla.

Parts of the Flower (Stamen) Male reproductive part Anther Produces pollen Filament Supports the anther

Parts of the Flower (Pistil) Female reproductive part Ovary Enlarged portion at base of pistil Produces ovules which develop into seeds Stigma Holds the pollen grains

Parts of the Flower (Pistil) Style Connects the stigma with the ovary Supports the stigma so that it can be pollinated

Fruit Types Dry, indehiscent fruit Dry, dehiscent fruit Fleshy fruit Other

True Fleshy Dry Indehiscent dehiscent False

Dry, indehiscent fruits Achene (lettuce) Samara (maple) Caryposis (wheat) Nut (almond)

Dry, Dehiscent Fruit Legume (soybean) Capsule (tobacco) Silique (Arabidopsis) Schizocarp (maple)

Fleshy Fruits Drupe (peach, nectarine) Berry (tomato) Pepo (cucumber) Hesperidium (citrus) Hip (rose) Pome (apple, pear)

Other Fruit Types Aggregate Multiple Accessory (False) mature ovaries from separate pistils of one flower (ex. raspberry) Multiple mature ovaries from separate pistils of several flowers (ex. pineapple) Accessory (False) fruit is something other than ovary tissue (ex. strawberry is a swollen receptacle, seeds are achenes)

Fleshy fruit types

SEED Seed Structures Germination Seed Seed coat Hypogeous Cotyledon Embryo Endosperm Hypocotyl Radicle Epicotyl (plumule) Germination Hypogeous Epigeous

Seeds Monocots: single cotyledon; endosperm and cotyledon are separate. Dicots: two cotyledons; endosperm is contained in the cotyledon.
