A technique of micropropagation is-
A technique of micropropagation is-
The correct option is B Somatic embryogenesis
The correct option is B.
The explanation for the correct option:
- Micropropagation is a technique used to produce plants asexually from vegetative plant parts under artificial conditions.
- Somatic embryogenesis is a process where a somatic cell is dedifferentiated to an embryonic stem cell.
- This stem cell has the ability to give rise to an embryo and thereby a whole plant.
- This process is carried out under controlled conditions.
- Other examples of micropropagation- callus culture (callus used to produce a whole plant), meristem culture(meristems are used to grow an entire plant), etc.
The explanation for incorrect options:
Option A:
When two different plants are hybridized to form a new hybrid plant (traits from both the plants), it is known as somatic hybridization.
Option C:
Embryo rescue is a technique where plant embryos are excised and grown in a suitable growth medium. It is also known as embryo culture. It is used in plants where embryos might not grow into viable plants.
Option D:
A protoplast is a cell without a cell wall. When protoplasts from two different plants are fused together, it is known as protoplast fusion. This is usually carried out to produce a new hybrid plant with desirable characteristics from both plants involved.
The final answer: A technique of micropropagation is Somatic embryogenesis.
