Study Notes
Leaf Structure and Function
- Epidermis: Outermost cell layer of a leaf providing protection.
- Cuticle: Waxy outer layer that minimizes water loss and protects the leaf.
- Palisade Layer: Key site for photosynthesis, situated beneath the epidermis; contains tightly packed cells for maximum light absorption.
- Spongy Layer: Located beneath the palisade layer, this layer has air spaces to facilitate gas exchange.
Photosynthesis Process
- Photosynthesis: Chemical process utilized by plants to convert sunlight into sugar using carbon dioxide and water.
- Chlorophyll: Green pigment in chloroplasts essential for capturing light energy during photosynthesis.
- Chloroplasts: Organelles within plant cells where photosynthesis occurs; contain chlorophyll.
- Glucose: Main product of photosynthesis, serving as an energy source for the plant.
Gas Exchange and Nutrient Transport
- Stomata: Small openings on leaf surfaces that enable gas exchange; allow entry of carbon dioxide and exit of oxygen.
- Guard Cells: Specialized cells surrounding stomata that regulate their opening and closing to control gas exchange and water loss.
- Veins: Vascular structures in leaves that transport water and nutrients from roots to cells and distribute sugars produced during photosynthesis throughout the plant.
Essential Gases
- Carbon Dioxide: Gas that is a critical reactant in the photosynthesis process, taken in through stomata.
