Figure 3

Phototropic response: A stage IVb sporangiophore exposed to a unilateral light stimulus from the left side causing it to bend towards the light source. The three images show the increase in bend angle with time. The light stimulus was initiated after ten minutes of steady growth rate, t = 10 min. The first photograph is the sporangiophore at t = 10 min. The second and third photographs are taken at t = 30 min and t = 50 min, respectively. A fiber is attached to the sporangium to determine the rotation rate of the helical growth rate.
