The method of reproduction of new plants by cells instead of seed is known is:___________?
Correct answer: A. Tissue culture
- A. Tissue culture
- B. Mutation
- C. Antibiosis

Tissue culture produces new plants from small pieces of tissue or cells under sterile conditions, without using seeds. Mutation changes genetic material, while recombination reshuffles genetic material; students may choose mutation because tissue-cultured plants can sometimes show variation.
