Caption

At the detachment area (abscission zone) cell processing enzymes (black and red Pac-Man-shaped circles) separate the cell wall between neighboring cells. Residuum cells (blue) are retained by the plant, while secession cells (light brown) of petals and sepals are shed and surrounded by a lignin brace (purple). The open cut is sealed with a protective cuticle layer (dark brown).
