Heathland: Hakea sericea - Leaf (TS)
This is the same section of Hakea sericea shown on the previous screen but recorded at a higher magnification.
The image shows a sunken stoma in the epidermis.
Note also the thick waxy cuticle that arches over the stoma,
and the resin-filled protective layer (hypodermis) between the epidermis and the palisade mesophyll.
The chamber created by the stomatal and cuticular arrangement minimises the rate of water loss
from the leaf because a layer of moist air can develop and be maintained.
Go to the menu and select 'Mesophyte' to compare this leaf with those of mesophytes.
