Question

The artificial or synthetic seeds are prepared by the following process

• A. Somatic hybridization and culture
• B. Somatic embryogenesis and immobilization
• C. Microprojectile and transformation
• D. Artificial pollination and embryogenesis

Answer 1

The Correct Option is B

The question is about the process used to prepare artificial or synthetic seeds. Let’s analyze the given options to determine the correct answer.

1. Somatic hybridization and culture: This technique involves the fusion of two distinct types of plant cells to form a somatic hybrid, primarily used for breeding and not directly related to synthetic seed production.
2. Somatic embryogenesis and immobilization: Somatic embryogenesis involves the formation of embryos from somatic or non-reproductive cells. These embryos can be encapsulated in a gel-like substance to immobilize them, creating synthetic seeds. This process is directly linked to the production of synthetic seeds, making it the correct answer.
3. Microprojectile and transformation: This usually refers to the delivery of genetic material into plant cells using a "gene gun" technique, which is a genetic engineering method, rather than for synthetic seed production.
4. Artificial pollination and embryogenesis: Artificial pollination involves the manual pollination of plants, and although embryogenesis is related to seed development, this combination does not specifically lead to synthetic seed creation.

Based on the above analysis, the correct answer is Somatic embryogenesis and immobilization. This method involves producing embryoids from plant tissue using somatic embryogenesis, which are then encapsulated in a protective medium, creating synthetic seeds that can be used for propagation.
