Stem and leaves are collectively known as shoot. A shoot of a plant is divided into nodes and internodes.

Node A particular part of a plant where a leaf is attached to the stem is called the Node.

A node has small axillary buds. These buds may develop into leaves, flowers or new branches.

Node is a part where repair, growth and cell divisions take place.

Internode The space between two continuous nodes is called an internode.

Internodes increase the length of the stem. In small-sized plants, internodes are small but in tall plants length of internodes is large.

Internodes don’t produce branches, buds, leaves, flowers and fruits.
