Pollination is the transfer of pollen from the male reproductive organs to the female reproductive organs of
A honeybee becomes coated in pollen while gathering nectar and transports the pollen as it goes from flower to flower.
The German physician and botanist Rudolf Jakob Camerarius (1665-1721) is credited with the first empirical demonstration that plants reproduce sexually. Camerarius discovered the roles of the different parts of a flower in seed production. While studying certain bisexual (with both male and female reproductive organs) species of flowers, he noted that a stamen (male pollen-producing organ) and a p…
Botanists theorize that seed plants with morphologically distinct pollen (male) and ovules (female) evolved from ancestors with free-sporing heterospory, where the male and the female spores are also morphologically distinct. The evolution of pollination coincided with the evolution of seed. Fossilized pollen grains of the seed ferns, an extinct group of seed-producing plants with fern-like leaves…
In general, pollination by insects and other animals is more efficient than pollination by wind. Typically, pollination benefits the animal pollinator by providing it with nectar, and benefits the plant by providing a direct transfer of pollen from one plant to the pistil of another plant. Angiosperm flowers are often highly adapted for pollination by insect and other animals. Each taxonomic group…
