Abiologist isolates cells that are not actively producing auxin from a section of a plant stem. she places them in a culture dish with a growth medium that keeps the cells alive.
when she adds auxin to the dish, the cells begin synthesizing more cellulose.

what is an alternative that the biologist could add instead of auxin that would allow her to observe the same response?

Gibberellins

Explanation:

Gibberellins can induce the production of cellulose with the release of secondary cell regulators through a repression cascade, thus, boosting Lignin production/deposition in the cell wall.

Lignin; polymer responsible for the thickness/rigidity of a cell wall.
