Plant reproduction

Plant reproduction is the production of new plants through sexual processes involving gametes or asexual growth from vegetative tissues. It enables plants to pass genetic material to offspring and establish new individuals.

Alternation of generations: A life cycle that alternates between multicellular haploid and diploid stages. Plant sexual reproduction unfolds across gametophyte and sporophyte generations.
Flower: The reproductive structure of flowering plants, containing organs that produce gametes or attract pollinators. Flowers position stamens and carpels for pollination and seed formation.
Plant propagation: The deliberate production of new plants by sexual or asexual methods. Horticulture applies plant reproductive processes to multiply useful plants.
Sexual reproduction: Reproduction involving the fusion of gametes to form offspring. It is the mode that combines parental genetic material in plants.
Pollination syndrome: A set of floral traits associated with pollination by a particular type of animal or abiotic agent. Floral form can reflect the agents that transfer pollen between plants.
Pollination: The transfer of pollen from an anther to a receptive plant reproductive structure. In seed plants, pollen transfer brings male gametophytes toward ovules.
Pollen: A microscopic structure that carries the male gametophyte of seed plants. Pollen transports male reproductive cells without requiring free-standing water.
Seed bank: A facility that stores seeds under controlled conditions to preserve plant genetic diversity. Seed storage safeguards offspring potential for restoration and future cultivation.
Asexual reproduction: Reproduction that produces offspring without the fusion of gametes. Vegetative propagation and apomixis are plant forms of this broader process.
Coevolution: Reciprocal evolutionary change between interacting species. Plant reproductive traits and pollinator traits can evolve in response to each other.
