Stoma also affect water conservation/loss

This is the evaporation of water from plants. Water is lost from a plant in the process of transpiration.

Transpiration Water is lost from three main areas of a plant: Stomata – in the leaves, account for about 90% of water loss Cuticle – the waxy layer, some water is lost through diffusion Lenticles – woody stems have loosely packed cork cells through which gas exchange occurs – a little water is lost here

Transpiration Water moves through the plant from roots to leaves and is lost to the air as water vapour. This is known as the transpiration stream. About 98% of water entering a plant is lost to the air through transpiration Remaining 2% is used for photosynthesis

Factors Affecting Transpiration Rates /webfeat/vis2005/show/transpiration.swf

Transpiration Deforestation decreases the rate of transpiration due to the large-scale removal of forest which normally add water vapour to the air This can have a serious effect upon the water cycle
