Question
Chapter 46, Problem 2RQ
Summary Introduction
To determine:
What is apical dominance?
Introduction:
The growth of plant is mediated by the plant hormones. Plant hormones are the chemicals secreted by specific cells and transported via xylem and phloem to other parts of the plants. Auxins and cytokinin are the two most important hormones responsible for stem and root branching.
Summary Introduction
To determine:
How do auxin and cytokinin interact in determining the growth of lateral buds?
Introduction:
Plant hormones play essential role in the life cycle of 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 growth and development of plants through its life cycle.

How does the signal transduction pathway for auxin that leads to cell wall loosening. Include the receptors ABP and ARF.
How does the auxin pathway possibly differ from the 'generic' signal transduction pathway? Consider expressing the cellular components that differ in the absence and presence of auxin.
