They freely expel a myriad of these pollen grains, and only a small percentage of them ends up captured by the female floral structures on wind-pollinated plants. [3] They are typically 20–60 micrometres (0.0008–0.0024 in) in diameter, although the pollen grains of Pinus species can be much larger and much less dense. [ 1 ]
Wind-pollinated species exhibit may flower in conjunction with trade winds to take advantage of more effective pollination conditions. [31] Determining the degree to which within-year flowering synchrony is a consequence of the constraints of abiotic resource availability versus an evolved trait with fitness benefits is a field of research ...
In leptosporangiate ferns, the fern catapults its spores 1-2 cm so they can be picked up by a second dispersal vector, often the wind. [4]Autochory is the dispersal of diaspores, which are dispersal units consisting of seeds or spores, using only the energy provided by the diaspore or the parent plant. [5]
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.
The process of allogamy involves two types of external pollinating agents, known as abiotic agents and biotic agents. The abiotic agents are water and wind. The biotic agents are insects and animals, which include bees, butterflies, snails, and birds. Wind pollination is referred to as anemophily, and water pollination is referred to as ...
The Private Life of Plants is a BBC nature documentary series written and presented by David Attenborough, first shown in the United Kingdom from 11 January 1995.. A study of the growth, movement, reproduction and survival of plants, it was the second of Attenborough's specialised surveys following his major trilogy that began with Life on Earth.

Baltimore Checkerspot (Euphydryas phaeton) nectaring at daisy (Argyranthemum)Pollination syndromes are suites of flower traits that have evolved in response to natural selection imposed by different pollen vectors, which can be abiotic (wind and water) or biotic, such as birds, bees, flies, and so forth through a process called pollinator-mediated selection.
