Haploid cultures can be obtained by culturing:

The plants produced from tissue culture are genetically identical to the original plant from which they are grown,so they are called:

Select the correct match for $X$ and $Y$:

Column $X$	Column $Y$
$(1)$ Callus culture	$(P)$ Hybrid embryo rescue
$(2)$ Suspension culture	$(Q)$ Differentiated mass
$(3)$ Embryo culture	$(R)$ Undifferentiated mass

In tissue culture experiments using tobacco callus,it was observed that when the culture medium contains $2 \ ppm$ of $IAA$ and $2 \ ppm$ of kinetin,an undifferentiated mass of callus is produced. If the ratio of kinetin to $IAA$ is increased,what will happen?

For cryopreservation,plant materials are frozen at (in $^{\circ} C$)

Which of the following cells cannot be grown under tissue culture conditions?
