Question

Virus-free plants can be generated through?
A. Meristem culture
B. Somatic hybridization
C. Callus culture
D. Micropropagation

Answer 1

Hint: Virus pretty unfastened vegetation can mainly be generated thru meristem culture. Cultivation of axillary or form of apical shoots meristems type is known as meristem culture, which truly is reasonably massive. Virus loose plant life may be generated via a meristem way of life, which is quite significant.

Complete answer:
When plant breeders normally want to re-generate flora that is virus-free the use of basically asexual multiplication, they frequently acquire the apical meristem from the infected plant and cultivate it a pretty appropriate medium, so that a brand new, surely entire and virus-unfastened plantlets increase, which generally in all fairness big.
Virus-unfastened flora can essentially be fashioned through meristem tradition due to the viruses unfold systematically within the honestly complete plant beside the meristems after they colonize a new plant host, via phloem vascular detail, absolutely opposite to popular perception. Normally plants essentially shoot kind of apical meristems honestly are virus-free, which surely is reasonably huge. The meristem grows into a pandemic-free simply shoot that for the maximum element is rooted to for the most part get a deadly disease-unfastened plant, which commonly is quite significant. Subsequently, Virus-unfastened flora can mainly be generated through the Meristem lifestyle, pretty contrary to popular perception.

Hence, the correct answer is A. Virus-free plants can be generated by Meristem culture.

Note: Meristem subculture can outline as the tissue lifestyle method which essentially makes the usage of commonly apical meristem with 1-3 leaf primordial by which clones of a plant can broaden by vegetative propagation in a kind of principal way. On this method, through the culturing of literally shoot meristem, adventitious roots can regenerate in a diffused way.
