The determination of the past arrangement of leaves from bare twig are
- Flower bud
- Lateral branching
- Lateral terminal bud
- Leaf scar
- Node
- Inter node
- Auxiliary buds
- Bud scale
- Terminal bud
Step-by-step explanation:
Terminal bud: it is the large bud at the apex of the twig. Uses of the bud is to protect the dormant meristem.
Bud scale: a small modified leaf on outside of bud.
Auxiliary bud: It is found just above the each leaf scar. Not all twig will have a full complementary of auxiliary buds. They frequently gets damaged.
Lenticles: Opening in the bark that allows for gas exchange into and out of underlying living tissues.
Leaf scars: It is present at the stem for the triangular regions.
