Limiting water loss Flashcards
1
Q
How is water loss limited in insects
A
Small SA:V ratio
Waterproof coverings
Spiracles
2
Q
How is water loss limited in leaves
A
Thick cuticle
Rolling up of leaves - Helps trap water vapour especially if stomata confined to lower epidermis
Hairy leaves - Traps water vapour
Stomata in pots or grooves
Reduces SA:V ratio of leaves
