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.
