Study Notes
Leaf Parts Definitions
- Palisade Layer: Contains chloroplasts for photosynthesis; typically located beneath the epidermis and plays a crucial role in the absorption of light.
- Cuticle: A waxy protective layer covering the leaf; helps reduce water loss and protects against environmental stressors.
- Spongy Layer: Located beneath the palisade layer; consists of loosely packed cells that facilitate gas exchange (carbon dioxide and oxygen) and moisture retention.
- Guard Cells: Specialized cells that control the opening and closing of stomata; regulate gas exchange and water loss in leaves.
- Epidermis: The outermost layer of cells that protect the leaf; serves as a barrier against pathogen entry and aids in the regulation of water loss.
- Phloem: Vascular tissue responsible for transporting nutrients and organic compounds (like sugars) throughout the plant.
- Xylem: Vascular tissue that transports water and minerals from roots to the rest of the plant; essential for maintaining plant hydration and nutrition.
- Mesophyll: Comprised of both palisade and spongy layers; the primary site of photosynthesis due to the high concentration of chlorophyll-containing cells.
