Flower
/ˈflaʊ.ɚ/
Definition
Flower is the reproductive structure of a flowering plant, usually containing stamens, which produce pollen, and one or more carpels or pistils, which contain ovules. Petals and sepals may surround these parts but are not the reproductive organs themselves. After pollination and fertilization, the flower can develop into fruit and seeds. Flowers may be single or grouped in an inflorescence, a cluster of flowers.
Function in Plants
- Sexual reproduction: In seed plants, flower is the main site of sexual reproduction, bringing pollen-producing parts and ovule-bearing parts together so pollination and fertilization can occur.
- Seed and fruit formation: After successful fertilization, structures within flower develop into seeds, and surrounding tissues may form fruit. This links flowering directly to the next generation and to seed dispersal.
- Pollinator interactions: Color, scent, nectar, and shape help flower attract pollinators such as bees, moths, birds, or bats. These traits can influence which animals visit and how efficiently pollen is moved.
- Identification and classification: The number, arrangement, and fusion of parts in flower are major traits used in plant identification and taxonomy, the science of naming and classifying plants.
- Gardening timing cue: For growers, the appearance of flower often signals a shift in care priorities, including pollination needs, pruning timing, and whether energy is going into blooms, seeds, or fruit.
