What is a Stem?

The stem is the ascending part of the axis bearing branches, leaves, flowers and fruits. It develops from the plumule of the embryo of a germinating seed. It bears nodes and internodes. What are nodes and internodes? The regions of the stem where leaves are born are called nodes. On the other hand, internodes are the portions between two nodes.

Functions of the Stem

The stem performs the two major functions of

• Spreading out branches bearing leaves, flowers and fruits.
• Conducting water, minerals and photosynthates.

Characteristics of Stems

• The stem is an ascending axis of the plant and develops from the plumule and epicotyl of the embryo.
• It is generally erect and grows away from the soil towards the light. Therefore, it is negatively geotropic and positively phototropic.
• The growing apex of stem bears a terminal bud for growth in length.
• In flowering plants, the stem is differentiated into nodes and internodes.
• The lateral organs of the stem (i.e., leaves and branches) are exogenous in origin (i.e., from the cortical region).
• The young stem is green and photosynthetic.
• Hair, if present, are generally multicellular.
• In mature plants, stem and its branches bear flowers and fruits.
