Study Notes
Aquatic Plants
- Roots: Do not attach to the river/pond bed to avoid being cut by currents.
- Stems: Elastic to resist water currents; contain air spaces for buoyancy.
- Leaves: Large air spaces for buoyancy and gas diffusion; thin cuticle (no need to reduce water loss); little lignin in xylem (supported by water); float on the surface for efficient light absorption; stomata on the upper surface to allow gas exchange and prevent water entry.
Xerophyte Plants
- Roots: Deep to access water at greater soil depths; branched to increase water absorption surface area.
- Stems: Upright shape to reduce heat absorption; succulent to store water; green (contains chlorophyll for photosynthesis).
- Leaves: Very small, spine-like to minimize water loss, prevent wind rupture, and protect from herbivory; fewer stomata to reduce water loss; hairs to decrease airflow and increase humidity.
