Question
Chapter 24.4, Problem 4MC
Summary Introduction
To analyze:
The hormonal changes that occur in the lateral buds after the shoot tip is pruned.
Introduction:
Pruning simply refers to the removal of undesirable plant parts to promote better development. Pruning helps in the stimulation of the growth of the lateral buds in a plant.

Examine the shoot system of a mature plant (Coleus blumei). Identify the shoot tip, nodes, internodes, leaves, and axillary buds. Each unit of stem that consists of a leaf, axillary bud and internode is referred to as a phytomere. Note that axillary buds always occur above a leaf. Axillary buds give rise to branch shoots. Thus, branching in a shoot system is exogenous (of external origin). How does this compare to branching in a root system?
What are three functions of the shoot apical meristem?
Shoot apical meristems make small groups of cells that protrude upward and develop into leaves. What are these small protrusions of cells called?
