structure of leaf and their functions

• Epidermal tissues - covered in a waxy cuticle which helps to reduce water loss by evaporation
• Upper epidermis - transparent so that light can pass through it to the palisade layer
• Palisade layer - lots of chloroplasts, meaning that they're near the tp of the leaf where they can get the most light
• Xylem and Phloem - form a network of vascular bundles, which deliver water and other nutrients to the entire leaf and take away the glucose produced by photosynthesis
• tissues of leaf - adapted for efficient gas exchange
