Question

Cholodny-Went theory explains the differential response of root and stem to different concentrations of auxins

• A. True
• B. False

Answer 1

The correct option is A

True

Cholodny-Went theory explains how the hormone auxin regulates different tropisms in plants. The directional growth in different parts of the plant is considered to be due to asymmetric distribution of auxin. Auxin is the sole hormone that controls growth in gravitropism and phototropism; the rate of growth depends on the concentration of auxin; and both gravity and unidirectional light affect the movement and concentration of auxin.
