Pollination is the transfer of pollen from an anther of a plant to the stigma of a plant, later enabling fertilisation and the production of seeds. [1] Pollinating agents can be animals such as insects, for example beetles or butterflies; birds, and bats; water; wind; and even plants themselves.
Plants which are not well-pollinated do not invest much in seed production, which can allow them to flower again in a short time. [9] This can re-synchronize individuals, because when they are well-pollinated and invest energy into seed production, they have limited resources to invest in flowering the following year.

Bee pollinating a sunflower. Pollen is transferred from anther of one plant to stigma of another as bee collects nectar. Pollen tubes are unique to seed plants and their structures have evolved over their history since the Carboniferous period. Pollen tube formation is complex and the mechanism is not fully understood.
Cross pollination produces seeds with a different genetic makeup from the parent plants; such seeds may be created deliberately as part of a selective breeding program for fruit trees with desired attributes. Trees that are cross-pollinated or pollinated via an insect pollinator produce more fruit than trees with flowers that just self ...
A pollinator garden is a group of plants grown together with the intention of attracting wild pollinators. Pollination is the reproductive process that enables plants to produce seeds. [5] When pollen from the male part of one flower is moved to the female part of another flower of the same species, fertilization occurs.
Plants fall into pollination syndromes that reflect the type of pollinator being attracted. These are characteristics such as: overall flower size, the depth and width of the corolla, the color (including patterns called nectar guides that are visible only in ultraviolet light), the scent, amount of nectar, composition of nectar, etc. [2] For example, birds visit red flowers with long, narrow ...
Pollen itself is not the male gamete. [4] It is a gametophyte, something that could be considered an entire organism, which then produces the male gamete.Each pollen grain contains vegetative (non-reproductive) cells (only a single cell in most flowering plants but several in other seed plants) and a generative (reproductive) cell.
With the decline of both wild and domestic pollinator populations, pollination management is becoming an increasingly important part of horticulture.Factors that cause the loss of pollinators include pesticide misuse, unprofitability of beekeeping for honey, rapid transfer of pests and diseases to new areas of the globe, urban/suburban development, changing crop patterns, clearcut logging ...
