In tissue culture, which description best fits its propagation type?

• A. It uses seeds to produce plants
• B. It is a form of both sexual and asexual propagation
• C. It is a form of asexual propagation
• D. It involves grafting onto rootstock

Answer: (C)

Tissue culture propagates plants asexually. It starts with a small piece of plant tissue placed in a sterile growth medium where hormones stimulate the tissue to form shoots and roots, producing new plantlets that are genetically identical to the original plant. Since no seeds or pollination are involved, this is asexual propagation, yielding clones rather than genetically diverse offspring. It does not involve seeds (that would be sexual propagation) and it does not use grafting onto rootstock (another vegetative method, separate from tissue culture).
