Relationship between Water loss and Leaf Structure
in strand one,we studied the internal and external structure of leaves. However,the structure of the leaves of different species of plants are not all the same.Leaves of one species may differ from those of another in respect of one or more of the following:

•their general shape and size •the arrangement of leaves in relation to each other •the thickness of the cuticle •the number and position of stomata

All the above structure differencesaffect the rate at which water vapour is lost by the plant by the process of transpiration. For example:

•The shapes and sizes of the leaves of some plants are altered so as to reduce the surface area exposed to the sun,thus reducing the transpiration rate e.g. in pinus,the leaves are needle-shaped.

•The leaves of some plants are situated close to each other so that they overlap and shade each other,ths reducing the transpiration rate.

•In some plants e.g. Nurium oleander,hairs occur on the leaves.This reduces air movement and also reflects the lightfalling on the leaves,thus reducing transpiration rate.

•The cuticle of the leaves and other aerial parts may be thickened to reduce water vapour loss through transpiration.

•The number of stomata may be reduced to cut down water loss.In some plants e.g. Hąķęą and Pìņųş, the stomata may be sunken so as to accumulate water vapour  molecules in sunken pockets, not exposed to direct sunlight. Jelmani (talk) 17:47, 20 May 2024 (UTC)
