Key Topics to Revise
1
External Structure of a Leaf
- A leaf has three main parts: petiole, lamina, and veins.
- Petiole is the stalk that attaches the leaf to the stem.
- Lamina (or leaf blade) is the flat, green part of the leaf where photosynthesis happens.
2
Types of Leaves
- Leaves are of two types: simple and compound.
- Simple leaves have an undivided lamina, e.g., mango, banana.
- Compound leaves are divided into smaller parts called leaflets, e.g., rose, silk cotton.
3
Venation in Leaves
- Venation is the arrangement of veins in the lamina.
- Two types: reticulate and parallel venation.
- Reticulate venation forms a net-like pattern — found in dicots like mango and peepal.
4
Functions of the Leaf
- Main functions: photosynthesis and transpiration.
- Photosynthesis: Leaves make food using sunlight, water, carbon dioxide, and chlorophyll.
- Transpiration: Loss of water vapour from leaves — helps in cooling and water absorption.
