Detailed explanation-1: -A seed bank or germplasm bank is a place where suitable conditions are maintained to conserve seed specimens of different plant species (wild or cultivated). The objective is clear: to ensure the preservation of as many plants as possible for posterity.

Detailed explanation-2: -A seed bank (also seed banks or seeds bank) stores seeds to preserve genetic diversity; hence it is a type of gene bank. There are many reasons to store seeds. One is to preserve the genes that plant breeders need to increase yield, disease resistance, drought tolerance, nutritional quality, taste, etc. of crops.

Detailed explanation-3: -The most widely used technique for conserving plant genetic resources is seed banking. Seeds are dried to low moisture content and stored at subzero temperatures in cold stores or deep freezers. According to FAO, this technique accounts for 90% of the 6 million accessions conserved ex situ globally.

Detailed explanation-4: -A seed bank is a place where seeds are stored to preserve genetic diversity for the future. They are usually flood, bomb and radiation-proof vaults holding jars of seeds from different plant species. The seeds are typically kept at low humidity and in cold conditions-around-20°C.

Detailed explanation-5: -The most common type of material in genebanks is seeds, many of which have evolved to last a long time if they are kept cool and dry. Some plants have seeds that cannot be dried and cooled for storage.
