Question

Which of the following is not an application of plant tissue culture?

• A. Recovery of healthy plants from diseased plants.
• B. Producing plants which are genetically identical to the parent plant.
• C. Changing the ploidy of plants.
• D. Propagation of a large number of plants in very short durations.

Answer 1

The correct option is C Changing the ploidy of plants.

• The plant tissue culture method is used to multiply the number of plants in a very short duration, which are identical to parent plants.
• Certain methods of plant tissue culture like meristem culture are used to recover healthy plants from diseased plants specially to obtain virus free plants, as the meristematic region is free from virus.
• The application of the tissue culture method is not used to change the ploidy of plants. Ploidy is the number of sets of chromosomes of the cell or an organism which can be diploid, triploid or polyploid.
