When a leaf or bud falls off, it leaves a scar behind. Leaf scars are crescent shaped and have small, circular bundle scars within them where vascular bundles traversed the plant tissues.

The abscission layer acts as a point of cleavage and the leaf breaks off leaving a cleanly shaped wound that is quickly healed over with protective cork.
Why are foliage leaves essential for the plant?
Foliage leaves are essential for the plant as leaf is the seat of several very important physiological processes like photosynthesis (which is related to the green colour), transpiration and respiration.
