Study Notes
Leaf Structure and Functions
- The cuticle is produced by the epidermis, the outermost layer of cells in a leaf, which acts as a protective barrier.
- The mesophyll layer contains a high concentration of chloroplasts, facilitating the process of photosynthesis.
- The palisade mesophyll, situated just below the upper epidermis, is positioned near the leaf surface to maximize light absorption for photosynthesis.
- Within the palisade mesophyll, chloroplasts are primarily located toward the upper side, optimizing exposure to sunlight.
- The spongy mesophyll layer consists of smaller cells with fewer chloroplasts when compared to the palisade mesophyll, allowing for gas exchange.
- The epidermis also plays a key role in preventing water loss through evaporation, aided by the cuticle’s waxy surface.
- The upper epidermis is transparent and very thin, allowing for maximum light penetration necessary for effective photosynthesis.
- The palisade mesophyll contains closely packed, rod-shaped cells enriched with chloroplasts, crucial for capturing light energy.
- Chloroplasts within the palisade mesophyll are strategically distributed to maximize light interception for efficient photosynthesis.
