In the initial stages of protoplast culture,sorbitol/mannitol is added
as an additional source of carbon
as an additional source of energy
to keep cells alive after the removal of cell wall
as an osmotic stabilizer
In crop improvement programmes,virus-free clones can be obtained through
grafting
hybridization
embryo culture
shoot apex culture
Somaclonal variation is seen in
tissue culture grown plants
apomicts
polyploids
vegetatively propagated plants
Assertion In plant tissue culture,somatic embryos can be induced from any plant cell.
Reason Any viable plant cell can differentiate into somatic embryos.
Both Assertion and Reason are true and Reason is the correct explanation of Assertion.
Both Assertion and Reason are true but Reason is not correct explanation of Assertion
Assertion is true but Reason is false
Both Assertion and Reason are false.
The callus is not formed in
tissue culture
suspension culture
clonal propagation
sexual reproduction
Differentiation of organs and tissues in a developing organism, is associated with
developmental mutations
differential expression of genes
lethal mutations
deletion of genes
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.
The process , in which mature differentiated cells reverse to meristematic activity to form callus is called
de-differentiation
differentiation
cyto-differentiation
re-differentiation
Undifferentiated mass of plant cells grown on nutrient medium, is called
callus
bud
clone
scion
In order to obtain virus-free plants through tissue culture, the best method is
protoplast culture
embryo rescue
anther culture
meristem culture
