Question

How are pollen banks useful?

Answer 1

Hint: Pollen is a powdery substance that is formed of pollen grains, which are male micro gametophytes of plants, to produce sperm cells (male gametes).

Complete step by step answer:
Pollen banks are used to retain pollen in appropriate settings for an extended length of time. In the pollen bank, pollens are frozen in liquid nitrogen, a process known as cryopreservation. Plant pollen is utilised in cross-pollination to transport haploid male genetic material from the anther of one flower to the stigma of another. Pollen from multiple plant kinds may be maintained at liquid nitrogen temperatures and utilised to infuse desired characteristics into hybrid cultivars. A particularly important use of the pollen bank is the preservation of biodiversity in the form of the value of genetic resources. It is critical to establish 'Pollen Banks,' in which pollen from the target species may be preserved as a genetic resource for the breeding operation. Farmers can benefit from pollen banks in the following ways:
1) The preservation of essential genetic resources to restore natural biodiversity.
2) This pollen might be employed in a variety of breeding programs for seed hybridization, metabolic and physicochemical investigations such as allergy research, and so on.

Additional Information : The most significant use of pollen banks is the preservation of biodiversity in the form of the value of genetic resources. It is critical to building 'Pollen Banks,' in which pollen grains from the target species are saved as a genetic resource for the breeding operation.

Note: Pollen grains contain a rough layer of sporopollenin that protects gametophytes as they go from stamens to pistils of flowering plants and from the male cone to female coniferous plants.
