Study Notes
- Crown architecture is important to position leaves on a stem or canopy to intercept direct light.
- Phyllotaxy is the art of leaf placement on a stem to reduce self-shading.
- The leaf area index (LAI) is a proxy for primary productivity at the individual or stand level.
- Plants are limited to the wavelengths within the visible light portion of the electromagnetic spectrum to carry out photosynthesis.
- Light in the understory of a forest comes in as diffuse light and sunflecks.
- Leaves at the top of the canopy are subject to serious thermal stress.
- Leaf fenestration is an adaptation to shade, heat, and wind stress.
- Submerged feathery leaves experience very little drag and by extension shearing stress.
- Developing buds can detect their external environment and develop accordingly.
- Plants respond to internal and external signals to regulate their growth and development.
