Study Notes
Leaf Structure
- Light absorption occurs at the top of the leaf
- Gas exchange occurs through stomata on the bottom of the leaf
- The leaf is made up of multiple layers
- The topmost layer is the cuticle (waxy)
- The upper epidermis protects the leaf
- The palisade layer contains chloroplasts for photosynthesis
- The spongy mesophyll layer allows for gas exchange
- The vascular bundle (xylem and phloem) transports water and nutrients (products such as sugars and water)
- The lower epidermis contains stomata for gas exchange
- Stomata are controlled by guard cells that regulate opening/closing
- Guard cells control the rate of water loss via transpiration
