The totipotency of a cell refers to the
flowering in a culture medium
development of fruit from a flower in a culture medium
development of total plant from a cell in culture medium
development of all tissues of all kinds from a cell in a culture medium
In callus culture,roots can be induced by the supply of
auxin
cytokinin
gibberellin
ethylene
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
Meristem culture is practised in horticulture to get
somaclonal variation
haplods
virus-free plants
slow-growing callus
For production of haploids,we culture
shoot tip
anther
root tip
none of these
The process , in which mature differentiated cells reverse to meristematic activity to form callus is called
de-differentiation
differentiation
cyto-differentiation
re-differentiation
In order to obtain virus-free plants through tissue culture, the best method is
protoplast culture
embryo rescue
anther culture
meristem culture
Axenic culture is
pure culture of a microbe without any nutrient
pure culture without any contamination
culture of tissue
culture of gene
Continuous addition of sugars in 'fed batch' fermentation is done to
obtain antibiotics
purify enzymes
degrade sewage
produce methane
Somaclonal variation is seen in
tissue culture grown plants
apomicts
polyploids
vegetatively propagated plants
