How do
Introduction:
When the embryonic plant which is present within seed start growing in the form of sprouting, break a dormancy period, and forms a seedling then the seeds are said to be germinated. During germination, root grows first and provides water and mineral from the soil to the developing shoots.

What promotes cell division and elongation in shoot?
Why can a monocot like an iris branch and increase its number of leaves? Is the fact that the shoot is a rhizome with adventitious roots important? Is water transported from one end of the shoot to the other?
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?
