Which of the following is icrorectly matched ?

Options

A. {:("Explant",,"Excised plant part used for callus formaton"):}`
B. `{:("Cytokinins",, "Root initiation in callus"):}`
C. `{:("Somatic embryo",,"Embryo produced form a vegetative cell"):}`
D. `{:("Anther culture",,"Haploid plants"):}`

Answer

To determine which of the following options is incorrectly matched, let's analyze each option step by step:

1. **Explant**:
- **Definition**: An explant is a piece of plant tissue (such as a part of a flower, stem, or leaf) that is excised and used for tissue culture.
- **Match**: This is correctly matched as explants are indeed used for callus formation in tissue culture.

2. **Cytokinin**:
- **Definition**: Cytokinins are a class of plant hormones that promote cell division and growth. They play a significant role in the initiation of callus formation.
- **Match**: This is also correctly matched as cytokinins are known to initiate callus formation.

3. **Somatic Embryo**:
- **Definition**: A somatic embryo is an embryo that is produced from somatic (vegetative) cells rather than from gametes (fertilization).
- **Match**: The statement claims that a somatic embryo is produced from a vegetative cell, but it incorrectly refers to it as an "adventive embryo." The correct term for an embryo produced from vegetative cells is "somatic embryo," not "adventive embryo." Therefore, this is incorrectly matched.

4. **Anther Culture**:
- **Definition**: Anther culture is a technique used to produce haploid plants from the anthers of flowers.
- **Match**: This is correctly matched as anther culture is indeed associated with the production of haploid plants.

**Conclusion**: The incorrectly matched option is **Somatic Embryo**, as it is misidentified in the context of the question.
