Modification of Leaves
Mainly Leaves perform photosynthesis but these are also participate in different roles like storage of food, support, defence etc. To perform these functions Leaves are modified into different forms like:
- Tendrils: When Leaves are modified into wiry and structures then these are called as tendrils, these are help the climbers to climb.
- Spines: When Leaves are converted into pointed structure and these structures protect the plant from herbivores.
- Phyllode: When petiole is modified into extended green structures which carries out photosynthesis.
- Storage leaves: Due to storage of water and food these Leaves are become fleshy.
- Cotyledons: Cotyledons are shown by mature embryo which may be one or two.
- Leaf bladders: Leaves of the some aquatic plants are modified into leaf bladders which trap the small insects.
- Leaf pitcher: Leaf lamina is modified into a lid which is called as pitcher and this trap the insects and fulfill nitrogen requirement.

Leaves – Morphology, Types & Modification
Leaves are the lateral appendages of the stem. The primary function of Leaves is to make glucose and produce oxygen by using sunlight, CO2 and H2O via the process known as photosynthesis. The structure of the leaf is composed of three parts including leaf base, lamina, and petiole. There are diverse types of Leaves present which depend upon the type of plant species. Chlorophyll is present in leaves which provides a green color and participates in photosynthesis.
