C3.1.22 (HL)—Auxin and cytokinin interactions Topic Practice
Students practise interpreting how auxin and cytokinin ratios influence root versus shoot development in plant tissue culture contexts.
How this is tested
- explain how varying auxin:cytokinin ratios in growth media determine whether explants form roots or shoots
- predict tissue culture outcomes given specified hormone concentrations
