Study Notes
Adaptive Features
- Some organisms, like fish with gills, have features that help them survive.
- Xerophytes are plants adapted to survive in areas with limited water.
Xerophyte Adaptations
- Xerophytes have adaptations to conserve water.
- Closing stomata helps reduce water loss when photosynthesis isn't possible.
- A waxy cuticle makes the leaf waterproof.
- Hairy leaves trap a layer of moist air.
- Deep roots help absorb water from deep in the ground.
- Reduced surface area of leaves (reduced SA) reduces water loss through transpiration.
Hydrophyte Adaptations
- Hydrophytes are plants adapted to live in water.
- Stomata are open, allowing for gas exchange.
- Plants are filled with air, providing buoyancy.
- Having large surface areas (large SA) to absorb dissolved nutrients in the water.
- Having feathery roots.
