parts of leaf

This video lesson is designed for 3-6-year-old children. It demonstrates the basic structure of a leaf and its parts. 

The science lesson provides a practical life experience by introducing the child to the different shapes and colors of leaves. and It helps them to learn about the different parts of a leaf. It guides the child about the structure of a leaf and its characteristics by labeling the different parts of the leaf, like apex, veins, stem, etc.

What is a leaf?

A leaf is a plant organ that is flat, thin, and usually green in color.

Leaves are green in color because pigment’ called chlorophyll. It helps plants to prepare food through photosynthesis. 


What are Parts of Leaf?

A. Leaf Stem / Petiole

It is the stalk that connects a leaf to the plant’s stem. It is made of vascular tissues.

Functions of Leaf Stem

  • It provides support to the leaf and keeps it erect.
  • It transports water and nutrients absorbed by the roots to the leaves.
  • It transports food to the rest of the plant.

 B. Leaf-blade or Lamina

It is the thin, flat part of the leaf that is typically green in color. It is characterized by green color, thinness, and smoothness. The leaf is divided into three parts: i) leaf apex – a tip of the leaf blade; ii) leaf margin – edge of the leaf; and iii) leaf veins – tiny capillaries.

Leaf veins are divided into two parts: the main/ central vein and the side veins. It helps in transporting water and nutrients throughout the leaf.

Functions of Leaf Blade

  • It helps plants prepare their food using raw materials like water, carbon dioxide, and minerals through photosynthesis.
  • It helps to perform transpiration.


Invite the child for a walk in your garden and ask them to pick a leaf and name the different parts, as shown in the video. Encourage them to connect with nature as they explore their surroundings.
