To obtain virus-free healthy plants from a diseased one by tissue culture technique, which part/parts of the diseased plant will be taken?
To obtain virus-free healthy plants from a diseased one by tissue culture technique, which part/parts of the diseased plant will be taken?
The correct option is C Both apical and axillary meristems
The correct option is C.
Explanation of the correct option:
- Even if the plant gets some viral infection still the meristematic region remains free.
- Hence, meristems are taken out from the plant and are grown in vitro to obtain a plant that is free from viruses.
- Therefore, both axillary and apical meristems are used for this purpose.
Explanation of the incorrect options:
Option A:
The epidermis of the plant gets infected by the virus easily thus it cannot be used for the tissue culture process.
Option B:
Along with the apical meristem, the axillary meristem is also used for tissue culture.
Option D:
Parenchyma isn't part of the meristem so it gets infected with the virus and thus, it is unhealthy for tissue culture.
Final answer: To obtain virus-free healthy plants from a diseased one by tissue culture technique, both apical and axillary meristems of the diseased plant will be taken.
