Part of the plant,which is cultured to obtain virus free clones,is
leaf
root tip
shoot tip
embryo
Axenic culture is
pure culture of a microbe without any nutrient
pure culture without any contamination
culture of tissue
culture of gene
In crop improvement programmes,virus-free clones can be obtained through
grafting
hybridization
embryo culture
shoot apex culture
Continuous addition of sugars in 'fed batch' fermentation is done to
obtain antibiotics
purify enzymes
degrade sewage
produce methane
A nutritionally wild type organism, which does not require any additional growth supplement is known as
phenotype
holotype
auxotroph
prototroph
In plant biotechnology, PEG is used in
protoplast isolation
cell culture preparation
protoplast fusion
hardening
The term 'totipotency' refers to
the capability of organism to regenerate its lost parts.
capability of somatic cells to produce complete organism
the introduction of foreign gene in a cell's DNA
the technique of growing immature embryos.
Hardening in tissue culture is
keeping at 30-50ºC temperature for about 30 minutes.
acclimatization tissue culture plants slowly before growing in the field.
plunging the vials into water at 37-40ºC
none of the above
In order to obtain virus-free plants through tissue culture, the best method is
protoplast culture
embryo rescue
anther culture
meristem culture
Somaclones are obtained by
tissue culture
plant breeding
irradiation
genetic engineering
