Transpiration
Xerophytic Plants are Adapted to Reduce Water Loss
Like cacti, pine tree and prickly pears adapted to live in dry climates
1. Stomata that are sunk in pits - so they're sheltered from the wind, helps slow transpiration
down
2. Layer of hairs in epidermis - traps moist air…

3. Humidity - lower the humidity, faster transpiration rate.
If air around plant is dry, water potential gradient between leaf and air increased
4. Wind - windier it is, faster transpiration rate.
Lots of air movement blows away water molecules from around stomata.
Increases water potential gradient which increases rate…
