Pollináció, or pollination, is a crucial biological process for the reproduction of flowering plants, ferns, and some gymnosperms. It involves the transfer of pollen, which contains the male gametes, from the anther of a flower to the stigma, the receptive tip of the pistil. This transfer is essential for fertilization, leading to the development of seeds and fruits.

There are several agents responsible for pollination. Wind pollination, known as anemophily, is common in grasses, conifers, and many deciduous trees. Insect pollination, or entomophily, is carried out by a vast array of insects such as bees, butterflies, moths, and beetles, which are often attracted to flowers by their color, scent, and nectar. Other animals, including birds, bats, and even some reptiles, also act as pollinators. Water pollination, or hydrophily, occurs in aquatic plants.

Pollination can be categorized into two main types: self-pollination and cross-pollination. Self-pollination occurs when pollen is transferred from the anther to the stigma of the same flower or another flower on the same plant. Cross-pollination involves the transfer of pollen from the anther of one plant to the stigma of a flower on a different plant of the same species. Cross-pollination generally leads to greater genetic diversity within a population.

The practice of pollination is vital for agriculture, as many food crops, including fruits, vegetables, and nuts, rely on it for successful yield. Efforts to conserve pollinator populations and habitats are increasingly important to maintain biodiversity and ensure food security.
