Abstract
The pollen tube of Prunus avium (cherry) consists of a growth zone of vesicles at the tip and an assemblage of organelles typical of an actively metabolizing cell. Electron opaque globules are closely associated with the plasma membrane and fibrillar cell wall layer at the tip. Acid phosphatase (EC 3.1.3.2) activity is localized in the membranes of 120 nm vesicles and ER system, the lumen of 50 nm vesicles, the plasma membrane and the tube nucleus.Keywords
