Below is the description of different types of leaves (of the plants) that grow in different biomes

• Pitcher Plant: The leaf of a pitcher plant is modified to attract and then digest insects and other small prey. Such plants typically live in nutrient-poor soils and rely on animal prey as their source of nitrogen.
• Living Stone: The two leaves of a living stone are adapted for hot, dry conditions. They are rounded, which minimizes the exposure of their surface to the air. They also have very few stomata.
• Spruce: The narrow leaves of a spruce tree contain a waxy epidermis as well as stomata that are sunken below the surface of the leaf. These adaptations reduce water loss from the leaves.
• Cactus: Cactus leaves are actually nonphotosynthetic thorns that protect against herbivores. Most of the plant’s photosynthesis is carried out in its stems.
