A-level Biology Notes

Xerophyte?

- a plant adapted to reduce water loss (reduce transpiration)

Adaptions of Xerophyte:

-Spiky, needle like leaves= reduced surface area

-thick waxy cuticle= waterproof, impermeable barrier

-densely packed spongy mesophyll= less air spaces, less water vapour build up 

-sunken stomata/ hairy leaves/ rolled up leaves= traps moist layer of air, reduces concentration gradient.
