Question

Which of the following events would likely occur if a plant tissue culture is treated with a solution containing a relatively high concentration of cytokinin and a relatively low concentration of auxin?

• A. Bud and shoot formation; rapid cell expansion; decreased cell division
• B. Bud and shoot formation; slow cell expansion; increased cell division
• C. Bud and shoot formation; rapid cell expansion; increased cell division
• D. Root formation; rapid cell expansion; decreased cell division

Answer 1

The correct option is B Bud and shoot formation; slow cell expansion; increased cell division

Cytokinin promotes bud and shoot formation and increased cell division; auxin promotes root formation and increased cell elongation. Thus, the correct answer is "option b".
