This botany lesson is designed for 6 to 12-year-old children. It demonstrates the basic structure of a stem, its parts, and its functions.

This video lesson provides a practical life experience of learning about the stems of different plants by taking a nature walk along with the child. It also introduces the child to the various parts of the stem, such as the nodes, petiole, axillary bud, etc.

Parts of a Stem, its Structures and Functions
The term ’stem’ refers to the plant structure supporting the plant and connecting the roots to the leaves and flowers. It is also called the central axis of the plant because it is found above the ground.

Stems are of two types:

(i) unbranched like the palm tree

(ii) branched like rose plants.

Note: stems of some plants grow underground, such as potatoes. It can be herbaceous (soft) or woody in nature (trunk).

Functions of a stem
The primary function of the stem is to provide mechanical support to the plant.
1. It also stores food for the plant.
2. It helps to transport absorbed water and minerals from roots to different parts of the plant.
3. It helps transport the food prepared by leaves using photosynthesis (i.e., sugars) to the rest of the plant.

Invite your child for a nature walk. Have them pick their favorite plant and ask them to identify the different parts of its stem
