The Leaf

Key Notes :

What is a Leaf?

• A leaf is a part of a plant.
• Leaves are usually green, flat, and thin.

Functions of Leaves:

• Food-making: Leaves make food for the plant through a process called photosynthesis.
• Breathing: Leaves help plants “breathe” by taking in carbon dioxide and releasing oxygen.
• Water Regulation: Leaves release water vapor into the air through tiny openings called stomata.

Parts of a Leaf:

• Blade (Lamina): The flat, green part of the leaf.
• Veins: Lines on the leaf that carry water and nutrients.
• Petiole: The stalk that connects the leaf to the stem.

Types of Leaves:

• Simple Leaf: A single blade (e.g., mango leaf).
• Compound Leaf: Made up of smaller leaflets (e.g., neem leaf).

Shapes and Sizes:

• Leaves come in different shapes (round, oval, long) and sizes (tiny to very large).

Importance of Leaves:

• Provide food and oxygen for humans and animals.
• Help keep the environment clean.

Fun Fact:

• Some leaves change color in autumn and fall off the trees.
