### sense in the lessons

In science lessons on plants and seasons, trees abscise their leaves in autumn: a layer of cells (the abscission layer) forms at the bottom of the leaf stalk, and the leaf falls. It is a rare, technical word; everyday English says «drop» or «shed». Phrases: «abscise leaves», «abscission layer».
