Plant reproduction by tissue culture differs from reproduction by meristem culture because a. tissue culture requires cells from a plant's root system, whereas any cell of a plant may be used for meristem culture. b. tissue culture propagation produces clonal plants, whereas meristem culture produces plants that may be genetically different. c. tissue culture produces plants that are virus-free, whereas plants produced by meristem culture may not be virus-free. d. plants produced by meristem culture are clones, whereas tissue culture does not produce genetically identical plants.

Ответ:
The answer is; B
Meristem cells are totipotent meaning they can differentiate to any type of plant cells. Therefore they can produce a variety of plant type depending on epigenetic. However, tissue culture is derived from already differentiated cells. Therefore these cells are already determined and can only produce cell type of that plant from which they were derived.
