Difference Between the Stem and the Root | Botany

The upcoming discussion will update you about the morphological difference between the stem and the root.

Difference # The Stem:

1. It develops from the plumule of the embryo.

2. It is the ascending axis of the plant.

3. The stem is usually green in colour and grows towards light.

4. It has distinct nodes and internodes and bears similar and dis­similar members.

5. Branches are exogenous in origin.

6. At the apex there is a terminal bud.

7. Multicellular or rarely unicellu­lar outgrowths may develop any­where on the stem surface.

Difference # The Root:

1. It develops from the radicle of the embryo.

2. It is the descending axis.

3. The root is non-green and goes away from light.

4. It has no nodes and internodes and bears only similar members.

5. Branches are endogenous in origin.

6. Root-cap is present at the apex.

7. Root-hairs are unicellular and they are the prolongations of the epi­dermal cells and not outgrowths. They are located at a particular zone called the root-hair zone.
