Animation 36.3 Quiz
A biologist 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?

B.
C.

Refer to the table below.
A biologist investigating the response of a particular plant species to light cues stumbles upon three mutant plant lines. Each displays a lack of normal phototropic behavior but varies in the auxin concentrations present in their growing tips. Based on the information given in the table, what could explain the behaviors of the three mutants?
A.
B.
C.
D.
