Question

A technique of micropropagation is
A) Somatic embryogenesis
B) Embryo rescue
C) Somatic hybridization
D) None of the above

Answer 1

Hint: Micropropagation is defined as an artificial plant production process which is initiated either by the act of the tissue culture or the cell culture techniques.

Complete answer:
In this artificial process of micropropagation, the plants are produced through in vitro technique by adopting asexual mode of reproduction.
Option A: The process of somatic embryogenesis is defined as an artificial process wherein a plant or its embryo are derived from a single somatic cell. Such embryos are usually formed from those plant cells which are not involved in the embryo development process i.e. the development of ordinary plant tissue. Therefore, this is the correct option.
Option B: Embryo rescue is defined as the technique of in vitro development of an embryo when they are likely to undergo an early abortion process. Therefore, this is the incorrect option.
Option C: Somatic hybridization is defined as the hybrid production induced through the process of protoplast fusion of two entirely different plant varieties or species. Therefore, this is the incorrect option.
Option D: As one of the options is correct, therefore, this is the incorrect option.

Thus, the correct option is (A) Somatic embryogenesis.

Note:Somatic embryos do not carry any endosperm of seed coat to cover it around. A few characteristics of somatic embryos are,
>They consist of shoot and root apex
>They have bipolar structure
>Their development comes under vegetative propagation
