Stem develops from the plumule and epicotyl of the embryo. 2. Generally, it is an aerial and ascending part of the plant axis. 3. A terminal bud is present at the apex of the main axis and lateral branches and is responsible for growth in length.
What is a diagnostic feature of stem?
Characteristics of Stems 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.

How can you tell the difference between stems and leaves?

The part of the plant which is present above the surface of the soil is called Stems, while Roots is the part of the plant which is present below the soil surface. Secondly stems arises from the plumule and roots from the radical of the embryo. Most importantly stems possess leaves, but roots do not.
What are the characteristics of stem?
Characteristics of Stem: The shoot system is heterogeneous and consists of stem, branches, leaves, and flowers. The stem is negatively geotropic (moves above the soil), negatively hydrotropic (moves away from the water) and positively phototropic (moves towards the light). The stem bears nodes and internodes.
What is stem and its function?
Stems have four main functions which are: Support for and the elevation of leaves, flowers and fruits. The stems keep the leaves in the light and provide a place for the plant to keep its flowers and fruits. Transport of fluids between the roots and the shoots in the xylem and phloem(see below)
