1. Pollination

   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, most often by an animal or by wind. Pollinating agents can be animals such as insects, birds, and bats; water; wind; and even plants themselves, when self-pollination occurs within a closed flower. Pollination often occurs within a species. When pollination occurs between species, it can produce hybrid offspring in nature and in plant breeding work. In angiosperms, after the pollen grain (gametophyte) has landed on the stigma, it germinates and develops a pollen tube which grows down the style until it reaches an ovary. Its two gametes travel down the tube to where the gametophyte(s) containing the female gametes are held within the carpel. After entering an ovum cell through the micropyle, one male nucleus fuses with the polar bodies to produce the endosperm tissues, while the other fuses with the ovule to produce the embryo. Hence the term: "double fertilisation". This process would result in the production of a seed, made of both nutritious tissues and embryo. In gymnosperms, the ovule is not contained in a carpel, but exposed on the surface of a dedicated support organ, such as the scale of a cone, so that the penetration of carpel tissue is unnecessary. Details of the process vary according to the division of gymnosperms in question. Two main modes of fertilisation are found in gymnosperms: cycads and Ginkgo have motile sperm that swim directly to the egg inside the ovule, whereas conifers and gnetophytes have sperm that are unable to swim but are conveyed to the egg along a pollen tube. The study of pollination spans many disciplines, such as botany, horticulture, entomology, and ecology. The pollination process as an interaction between flower and pollen vector was first addressed in the 18th century by Christian Konrad Sprengel. It is important in horticulture and agriculture, because fruiting is dependent on fertilisation: the result of pollination. The study of pollination by insects is known as anthecology. There are also studies in economics that look at the positives and negatives of pollination, focused on bees, and how the process affects the pollinators themselves.

1. pollination

   Pollination is the process in plants where pollen is transferred from the male reproductive organs (anther or stamen) to the female reproductive organs (stigma) of a flower. This process aids in the fertilization and reproduction of the plant, eventually leading to the production of fruits and seeds. Pollen can be transferred by various agents like wind, water, or animals such as insects and birds.

1. Pollination

   Pollination is the process by which pollen is transferred in the reproduction of plants, thereby enabling fertilization and asexual reproduction. In spite of a common perception that pollen grains are gametes, like the sperm cells of animals, this is incorrect; pollination is a phase in the alternation of generations. Each pollen grain is a male haploid plant, a gametophyte, adapted to being transported to the female gametophyte, where it can achieve fertilization by producing the male gamete. As such the Angiosperm successful pollen grain containing the male gametes gets transported to the stigma, where it germinates and its pollen tube grows down the style to the ovary. Its two gametes travel down the tube to where the gametophyte containing the female gametes are held within the carpel. One nucleus fuses with the polar bodies to produce the endosperm tissues, and the other with the ovum to produce the embryo Hence the term: "double fertilization". In gymnosperms the ovule is not contained in a carpel, but exposed on the surface of a dedicated support organ such as the scale of a cone, so that the penetration of carpel tissue is unnecessary. Details of the process vary according to the division of Gymnosperms in question.

Examples of pollination in a Sentence

1. Bryant McGill:

   Where wise actions are the fruit of life, wise discourse is the pollination.

2. Wandile Sihlobo:

   For the summer maize crop we need the rain immediately as it is now in the pollination stages. April is too late for the summer crops, and for the winter crop, the forecast is not clear.

3. Sergey Petrov:

   The robot bee will tell the other bees where to go to find nectar and pollen, not only will this direct them to certain fields for pollination but also navigate the bees away from dangerous areas, like where pesticides are being used.

4. Qianshi Lin:

   What's particularly unique about this carnivorous plant is that it traps insects near its insect-pollinated flowers, on the surface, this seems like a conflict between carnivory and pollination because you don't want to kill the insects that are helping you reproduce.

5. Ralph Harbach:

   It might be possible to wipe out a few species but we don't want to wipe out the good guys because a lot of them serve as food for frogs, fish and bats, many also visit flowers to feed on nectar and may play a role in pollination.
