Question

Difference between synthetic seed and natural seed

Answer 1

Answer:

The difference between the seed with zygotic embryo and artificial seed with soma­tic embryo are:

Natural Seeds:

1. Hard seed coat present.

2. Embryos are much protected within cotyledons or endosperm.

3. Embryos undergo controlled desiccation by the maternal tissue and have a natural dormancy period.

4. The natural seeds have their own storage reserves like endosperm or cotyledons to provide food during germination.

Synthetic Seeds:

1. No seed coat, only encapsulated.

2. Embryos are not protected within any kind of maternal tissue.

3. Embryos do not pass through any kind of desiccation and they the do not have any dormancy period.

4. The artificial seeds do not have their own storage tissue, the nutrients or growth regu­lators can be supplied within the encapsu­lating material.

Answer 2

Synthetic seeds are plant propagation materials that have been artificially encapsulated, whereas natural seed is the seed of non-monogerm types that have not been processed as a precise seed.

Synthetic seed:

• A synthetic seed is an artificially encapsulated somatic embryo (protocorm-like entities in the case of orchids) or meristematic tissue (shoot ends, nodal segments, corm, and bulb) that acts as a seed and has the ability to germinate into complete plantlets.
• Artificial seeds are artificially encapsulated somatic embryos (typically) or other vegetative elements such as shoot buds, cell aggregates, auxiliary buds, or any other micropropagules that can be deposited as seeds and grown into plants in vitro or in vivo.

Natural seed:

• The embryonic stage of the plant life cycle is represented by the seed.
• Most seeds are made up of three parts: the embryo, the endosperm, and the seed coat.
• The embryo is a microscopic plant with a root, a stem, and one or more leaves.
• The endosperm is the seed's nutritive component, which is often a combination of starch, oil, and protein.
