Q
How do terrestrial plants and insects balance the need for gas-exchange and the need to conserve water?
A
=INSECTS
-Small surface area to volume ratio
-Waterproof covering of chitin
-Spiracles that can close
=PLANTS
-Thick cuticle
-Rolling up of leaves to create a high water potential immediately outsied the stomata
-Hairy leaves to trap escaping moisture (And create a high water potential)
-Stomata in pits/grooves to reduce water loss by evaporation
-Reduced SA:V of leaves
