Q.By the application of tissue culture, one important product is formed :

Artificial (synthetic) seeds, or synseeds, are manufactured by encapsulating embryoids - somatic embryos produced through in vitro culture - inside an inert coating material, typically agarose or sodium alginate, which forms an artificial seed coat and an artificial endosperm layer around the embryo. They can also be built up starting from single cells taken from any part of the plant, provided the cells go on to divide and form a cell mass with dense cytoplasm, a large nucleus, and storage reserves (starch grains, proteins and oils) similar to a true seed's. Artificial seeds have several practical advantages over true seeds: millions can be produced at any time at low cost; they offer an easy way to propagate genetically engineered plants with desirable traits; the genotype of the resulting plants is easy to test in advance; they can potenti …
