Photographs enlarged from portions of a motion photomicrograph, showing the method of cell wall penetration by Pythium hyphae.
A. — Shows the hypha growing against the potato cell wall. Sufficient pressure has already been applied to cause the hypha to bend. Notice that this bending increases in later photographs.
B. — A little later stage than A.
C. — The tip has broken through as a small tube
D. — Penetration is complete. Notice the constriction of the hypha at the point where it penetrates the potato cell wall.
