Abscission (from Latin abscindere, from ab- ‘off, away’ + scindere ‘to cut’) is the shedding of a body part. It most commonly refers to the process by which a plant intentionally drops one or more of its parts, such as a leaf, fruit, flower or seed, though the term is also used to describe the shedding of a claw by an animal.
