Chapter 46, Problem 1FIB
Summary Introduction
Introduction:
Plant hormones play an essential role in the life cycle of plants. Plant hormones are the chemicals secreted by specific cells and transported via xylem and phloem to other parts of the plants. There are six major plant hormones: auxin, gibberellin, cytokinin, ethylene, abscisic acid, and florigen. Each plant hormone has different function and they regulate the development of plants through its life cycle.

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?
The major site of cytokinin synthesis is the_______ .Cytokinin_______ sprouting of lateral root branches, and______ branching of________ .
