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.
