A set of vocabulary flashcards covering key concepts and terms related to plant anatomy as discussed in AGRI 103.

Flower

The reproductive structure of flowering plants, involved in sexual reproduction.

Stamens

The male component of a flower that includes the filament and anther, which produces pollen.

Pistils

The female portion of a flower consisting of the stigma, style, and ovary.

Petals

Modified leaves that attract pollinators and protect immature stamens and pistils.

Sepals

Green leaf-like structures at the base of the petals.

Pollination

The transfer of pollen from the anther to the stigma.

Fertilization

The union of male sperm and female ovules that leads to the formation of seeds.

Self pollination

The transfer of pollen from the anther to the stigma of the same flower.

Cross pollination

The transfer of pollen from the anther of one plant to the stigma of another plant.

Complete flowers

Flowers that have all four parts: stamens, pistils, petals, and sepals.

Incomplete flowers

Flowers that lack one or more of the four flower parts.

Perfect flowers

Flowers that have both stamens and pistils.

Imperfect flowers

Flowers that lack either the stamen or the pistil.

Monoecious plants

Plants that have separate male and female flowers on the same plant.

Dioecious plants

Plants that have separate male and female plants.

Inflorescence

The arrangement of flowers clustered together on branches.

Florets

Individual flowers that are part of an inflorescence.

Fruits

The mature ovary containing seeds after fertilization.

Dehiscent fruits

Fruits that split open at maturity to release seeds.

Indehiscent fruits

Fruits that do not split open when mature.

Monocots

Plants that have a single seed leaf (cotyledon) in the seed.

Dicots

Plants that have two seed leaves (cotyledons) in the seed.
